Structural Characteristics

3. Internal metal shielding partition isolates high-power drive circuit and low-signal encoder circuit to eliminate signal crosstalk
4. Integrated STO safety torque-off circuit independent of main control chip, hardware-level safety protection without software dependency
5. Daisy-chain SERCOS bus interface allows series connection of multiple MC-4110 series drives to single MAX-4 master controller

   Working Principle

   1. SERCOS real-time bus receives synchronized position trajectory commands sent by upper MAX-4 motion controller every microsecond control cycle.
   2. Internal DSP chip compares target position value with real-time position feedback signal transmitted from motor encoder.
   3. Position loop, speed loop and torque loop operate sequentially to calculate required output current, driving internal IGBT power module to convert alternating current for servo motor operation.
   4. If STO safety circuit is triggered, power supply to motor winding is physically cut off at hardware level to eliminate output torque immediately.
   5. Built-in fault monitoring circuit continuously samples current, temperature and voltage parameters. Once exceeding preset limits, the drive locks output and activates corresponding fault indicator light for troubleshooting.

   Installation Requirements

   1. Install vertically on standard TS35 DIN rail; horizontal mounting is prohibited as it obstructs natural convection cooling of the aluminum heat sink.
   2. Maintain minimum 15 mm vertical clearance between adjacent servo drives inside control cabinets.
   3. Separate motor power cables and encoder signal cables into different wiring channels. Shielded twisted-pair cables are mandatory for encoder wiring, with single-point grounding of shielding layer.
   4. SERCOS bus cable must follow official wiring specifications. Daisy-chain wiring terminal sequence cannot be reversed. Terminating resistor should be mounted on the last drive of the bus chain.
   5. Connect PE protective earth terminal reliably to cabinet ground bar to suppress electromagnetic interference.
   6. Ensure cabinet ambient temperature stays within rated range; install exhaust fans for continuous high-load operation.

   Function & Feature Highlights

   1. Triple closed-loop control modes: position, speed and torque, freely switchable to satisfy diverse mechanical motion demands.
   2. Independent hardware-based Safe Torque Off safety function, reaching Category 3 safety level for machinery applications.
   3. Compatible with multiple encoder types, supporting incremental, sine/cosine and absolute encoder feedback.
   4. SERCOS II high-speed real-time bus enables nanoscale synchronized coordination with ELAU MAX-4 master controller.
   5. Built-in auto-tuning function to identify motor parameters and optimize control gain rapidly during commissioning.
   6. Comprehensive fault detection including overcurrent, overvoltage, undervoltage, overheating, encoder loss and wiring breakage.
   7. Slim DIN rail design reduces cabinet space occupation for multi-axis packaging machinery layouts.

   Typical Application Scenarios

   • High-speed packaging machines coordinated with PacDrive MAX-4 controller
   • Pharmaceutical cartoning, filling and blister forming equipment
   • Labeling machines, slitting and winding converting machinery
   • Food and beverage bottling, capping and conveying automated lines
   • Printing industry register control servo positioning axes
   • Automated handling and palletizing auxiliary servo axes

   Operation & Maintenance Precautions

   1. Disconnect three-phase main power and wait at least 5 minutes before opening enclosure, to allow internal DC bus capacitors to fully discharge.
   2. Prevent conductive dust, oil mist and water vapor from entering the drive housing.
   3. Use dry compressed air to clear dust accumulated on heat sink fins every three months.
   4. Do not disconnect encoder cables while equipment is powered on; hot plugging may damage encoder interface circuits.
   5. Verify STO circuit integrity regularly after machine maintenance to guarantee safety protection effectiveness.
   6. Avoid long-term continuous operation above 80% rated output current, which accelerates aging of internal power semiconductors.
   7. Firmware upgrade must be performed under stable power supply; power interruption during flashing results in firmware corruption.
