Working Principle

1. Real-time axis position, speed and torque feedback data transmitted from IndraDrive servo drives via internal high-speed backplane bus.
2. Dual redundant safety ASIC cores synchronously execute cross-verified safety motion limit calculation logic.
3. When axis movement exceeds pre-configured safe speed or position thresholds, module triggers STO safety torque cut-off signal to corresponding servo drives instantly.
4. External safety discrete signals (emergency stop, safety door switch) are sampled via front terminal interface and integrated into overall machine safety interlock logic.
5. All safety violation events, axis faults and communication errors are stored to on-board non-volatile memory for equipment failure traceability.

Function Features

1. Dual redundant safety processing architecture achieves PL d / SIL2 safety rating for automated machinery multi-axis motion control.
2. Native support for core safe motion functions: STO, SSM and SPL without external separate safety relay hardware.
3. Centralized safety monitoring for maximum 4 synchronized servo axes reduces cabinet safety control hardware quantity.
4. Real-time bidirectional data exchange with IndraDrive servo system for closed-loop safety motion supervision.
5. Permanent fault log storage retains safety trigger records for equipment maintenance and machinery safety audit.

Advantage Highlights

1. Original Bosch Rexroth matching hardware with zero compatibility deviation for full IndraDrive servo series.
2. Integrated aluminum shielding housing adapts to heavy EMI workshop environments of CNC machine tools, packaging production lines and robotic equipment.
3. Compact form factor occupies minimal rack space compared to split safety relay and motion monitoring hardware.
4. Dual-core cross-verification eliminates single-point failure risk of machinery safety motion supervision.
5. Unified spare part number R911311065 for global asset procurement and inventory archive management.

Applicable Industries

CNC precision machining equipment, automated packaging production lines, multi-axis robotic handling machinery, printing press servo control systems, textile automated weaving machinery, lithium battery manufacturing automation lines.

Installation Requirements

1. Slide module horizontally into dedicated FCS slot of Rexroth IndraControl CS01 standard subrack, lock side mounting screw securely.
2. Servo backplane communication cables use factory-specified shielded bus cable, shield double-ended grounded at cabinet earth bar.
3. Separate safety signal wiring and servo motor power cables with minimum 15cm routing clearance to avoid high-frequency interference.
4. Reserve vertical ventilation gap of minimum 25mm between adjacent rack modules for passive heat dissipation.
5. Machine cabinet cooling system shall maintain internal ambient temperature below +55℃ continuously during production operation.

Usage Precautions

1. Hot-swap of module during machine automatic running cycle will trigger full-axis STO safety shutdown and unplanned production halt.
2. Input signal voltage exceeding 30VDC will damage front-end safety signal sampling circuit permanently.
3. After module replacement, complete full-axis safe motion limit function test before resuming automated production.
4. Communication bus terminals must be cleaned with anhydrous alcohol every 6 months to remove conductive dust accumulation.
5. Do not install module adjacent to servo drive power unit heat sinks to avoid excessive ambient operating temperature.
