Teknic SST-1500-YCX

Product Short Description

Product Brief Overview

Teknic SST-1500-YCX belongs to the same flagship SST high-speed servo control product series as the XCX model, with a rated matching motor power of 1500W. The core difference between YCX and XCX lies in the built-in brake control power drive circuit dedicated to servo motors with holding brakes, while retaining all high-performance motion control algorithms, multi-layer safety protection logic and industrial communication interfaces of the XCX version. This servo drive integrates an independent high-current brake excitation output circuit inside the aluminum alloy heat dissipation shell, eliminating the need for external auxiliary brake relay modules to control motor holding brakes.

Core Function Features

Multi-Mode Closed-Loop Motion Control Algorithms

All high-performance motion control algorithms of the XCX model are fully retained, including switchable position/speed/torque three control modes, FOC field-oriented vector current control eliminating torque ripple, multi-stage position/speed/torque feedforward compensation reducing high-speed motion tracking lag error, configurable arbitrary fractional electronic gear ratio for multi-axis synchronous linkage.

Dedicated Built-In Motor Holding Brake Control Function (Core Differentiated Feature vs XCX)

Independent integrated 24V brake power drive circuit: No external relay contactors required for motor brake coil driving; the internal dedicated power circuit directly supplies excitation current to the motor holding brake, simplifying cabinet wiring and reducing electrical component failure points caused by additional relays.
Configurable brake timing delay logic via internal parameters: Two adjustable delay time parameters are provided: brake release delay time and brake lock delay time.
- Brake release delay: After the servo drive outputs a torque enable signal to start motor rotation, the drive maintains the brake locked state for the set delay time first, then outputs excitation current to release the brake, ensuring the motor generates stable output torque before mechanical braking is lifted, preventing gravity load axis sliding during brake release.
- Brake lock delay: When the servo drive receives a servo disable signal or triggers a fault torque cut-off, the drive continues to output motor torque to maintain axis position for the set delay time, then cuts off brake excitation current to lock the mechanical brake, eliminating workpiece falling or vertical axis free fall caused by delayed mechanical brake response after motor torque disappears.
Brake fault real-time detection function: The built-in brake circuit continuously samples the coil current of the motor holding brake; if open-circuit (brake coil wire breakage) or short-circuit (brake coil insulation damage short circuit) faults are detected, the drive immediately triggers a dedicated brake fault alarm code, cuts off motor torque output synchronously and records the fault event in internal flash memory for later maintenance traceability.

Comprehensive Multi-Layer Hardware & Software Safety Protection System

All safety protection mechanisms of the XCX model are fully inherited, including instantaneous overcurrent hardware protection, DC bus overvoltage/undervoltage protection, IGBT power module two-stage overtemperature protection, motor long-term thermal overload protection, encoder signal loss fault protection, hardware optocoupler isolated emergency stop safety circuit complying with EN 60204-1 international machinery safety standards. The YCX model adds an independent brake circuit short-circuit and open-circuit fault protection branch on the basis of the original protection system.

The digital output terminals add optional linkage control functions for external auxiliary mechanical brakes.

Consistent complete debugging and monitoring functions with the XCX model: Windows-based Teknic ServoTools graphical parameter configuration software with built-in real-time motion curve oscilloscope, front panel digital LED display and physical operation buttons for on-site local parameter adjustment and fault code reading, internal flash memory continuous recording of historical operating data and fault event logs, automatic power-off non-volatile storage of all modified servo configuration parameters with over 10 years data retention life.

Material Composition & Structural Characteristics

The overall material composition, internal layered isolation circuit layout, integral aluminum alloy heat dissipation shell structure, front panel human-machine interaction centralized layout and rear panel power terminal centralized wiring layout are completely consistent with the Teknic SST-1500-XCX servo drive. The only structural difference lies in the internal circuit board layout: the YCX model reserves an independent PCB layout area for the dedicated brake drive power circuit on the lower high-current power circuit layer, with additional high-current copper foil wiring and independent overcurrent protection fuses for the brake excitation output channel, while the XCX model’s power circuit board does not contain this dedicated brake drive circuit layout space and supporting power components.

Installation Requirements

All mechanical mounting specifications, cabinet internal reserved convection clearance standards, power/signal wiring classification separation rules, cable selection criteria and terminal wiring torque tightening standards are fully consistent with the Teknic SST-1500-XCX model. The only additional wiring specification unique to the YCX variant: dedicated two-core shielded brake coil signal cables shall be used to connect the motor holding brake coil terminals to the dedicated brake excitation output terminals on the rear panel of the servo drive; the brake cable shielding layer shall be single-ended grounded at the servo drive side to eliminate electromagnetic interference on brake coil excitation current signals.

Application Scenarios

All applicable equipment categories of the XCX model are fully covered, with priority targeted at automated mechanical axes carrying gravity loads that require power-off holding braking:

Vertical lifting automated equipment: Vertical material lifting linear axes of automated three-dimensional warehouses, vertical lifting cutting platforms of CNC machining equipment, vertical lifting feeding axes of packaging machinery
Multi-joint industrial robot vertical joint axes: Vertical shoulder joint axes and vertical wrist joint axes of medium-load articulated assembly robots, vertical lifting joint axes of palletizing robots
Precision vertical positioning medical and laboratory equipment: Vertical sample lifting test platforms of medical laboratory automatic detection equipment, vertical film feeding positioning axes of medical imaging auxiliary equipment
Automated elevator-type material transfer machinery for electronic manufacturing: Vertical lifting transfer axes of PCB automatic production lines, vertical lifting loading axes of semiconductor wafer testing equipment

Working Principle

The four core coordinated operating subsystems (DC bus power conversion subsystem, FOC vector current control subsystem, multi-loop closed-loop feedback control subsystem, communication & digital I/O logic control subsystem) operate according to the identical working logic of the XCX model. The YCX model adds an independent fifth dedicated brake drive control subsystem to handle motor holding brake timing and excitation current control:

After the main control chip outputs a servo torque enable signal, the brake drive subsystem starts the preset brake release delay timer; after the timer counts down to zero, the internal brake power circuit outputs stable 24V excitation current to the motor brake coil, lifting the mechanical brake friction plate and allowing the motor to rotate freely. When a servo disable signal or fault torque cut-off signal is received, the brake drive subsystem activates the brake lock delay timer; the main power drive circuit continues to output holding torque to maintain axis position during the countdown process. Once the timer completes counting, the brake drive subsystem cuts off all excitation current output to the brake coil; the built-in brake spring of the motor pushes the friction plate to lock the motor rotor, realizing reliable mechanical holding braking for gravity load axes. The brake circuit current sampling module continuously monitors the coil excitation current during the entire brake operating cycle; abnormal current values corresponding to coil open-circuit or short-circuit faults trigger dedicated brake fault alarm logic synchronously.

Use Precautions

All power supply operation precautions, wiring & installation precautions, daily operation & debugging precautions, maintenance & storage precautions applicable to the XCX model fully apply to the YCX variant. Two additional unique usage precautions for the built-in brake drive circuit of the YCX model:

Strictly prohibit parallel connection of multiple motor brake coils to the YCX model’s dedicated brake excitation output terminals. The internal brake drive circuit is designed with a maximum continuous output current limit of 2A, only supporting single servo motor holding brake coil driving; parallel connection of multiple brake coils will cause overcurrent burnout of the internal brake power circuit and trigger permanent hardware damage. If multiple brake axes need to be controlled simultaneously, configure independent SST-1500-YCX servo drives for each axis separately.
Do not arbitrarily modify the brake release delay and brake lock delay timing parameters to extremely short values during equipment parameter debugging. Excessively short brake release delay time will lead to insufficient motor torque output before the mechanical brake is released, causing gravity load axis sliding and workpiece falling; excessively short brake lock delay time will result in the mechanical brake locking the rotor before the motor output holding torque disappears, generating severe mechanical friction wear on the brake friction plate and greatly shortening the service life of the motor holding brake assembly. Adjust the two delay parameters step by step according to the actual mechanical movement speed and load weight of the equipment axis, and conduct multiple repeated motion tests to confirm stable braking timing without sliding or friction wear phenomena before formal mass production operation of the equipment.
