• X14: Servo bus OUT (daisy‑chain to next drive)

4. Main Features

• High Precision: Vector control for accurate torque/position control

• Dynamic Braking: Integrated braking unit for regenerative energy dissipation

• Drive Monitoring: Real‑time monitoring of current, voltage, temperature, and encoder signals

• Fast Response: 4 kHz/8 kHz PWM for high‑speed motion

• Compact Design: 88 mm width for space‑saving cabinet integration

• Easy Configuration: Parameters set via KUKA WorkVisual or teach pendant

5. Safety Instructions

• High Voltage: DC 565/675 V and AC 400/480 V; disconnect power before servicing

• Capacitor Discharge: Wait ≥5 minutes after power‑off for intermediate circuit capacitors to discharge

• No Modification: Do not bypass or modify protection circuits (overload, short‑circuit, overvoltage)

• Cooling: Ensure unobstructed airflow; do not block ventilation slots

• Work Envelope: Keep clear of moving robot axes during operation

6. Installation & Wiring

1. Mounting: Attach to DIN rail or panel; allow 50 mm clearance for cooling airflow

2. Power Wiring: Connect DC intermediate circuit to X1 (observe polarity); tighten torques to 1.2 Nm

3. Motor Wiring: Connect 3‑phase motor and brake to X2; shield cable per EMC guidelines

4. Bus Connection: Link X13 (IN) to controller; X14 (OUT) to next drive in chain

5. I/O Wiring: Connect safety signals (E‑Stop, door interlocks) to X11; use twisted pair cables

6. Grounding: Earth drive, motor, and cabinet per local codes; ensure low‑resistance ground path

7. Operation

7.1 Power‑Up

1. Verify all connections are secure and correct

2. Apply 3‑phase AC power to controller; intermediate circuit charges to 565/675 V DC

3. Check X1 LEDs: Power (green) ON, Fault (red) OFF

4. Enable drive via controller (KCP2); Servo Ready (yellow) LED ON

7.2 Normal Operation

• Manual Mode (T1/T2): Drive follows jog commands from teach pendant; adjusts torque/speed dynamically

• Automatic Mode (AUT): Executes programmed motion (PTP/LIN/CIRC); maintains precise position control

• Fault Handling: Red Fault LED ON; drive disables motion. Check fault code via teach pendant; resolve issue before resetting

8. Maintenance

• Daily: Check LED status; inspect cables for damage or loose connections

• Weekly: Clean cooling fan and ventilation slots; verify airflow

• Monthly: Tighten connectors (torque 1.2 Nm); check motor insulation resistance

• Quarterly: Backup drive parameters via WorkVisual; test fault reset functionality

• Annual: Replace cooling fan (if worn); inspect electrolytic capacitors for bulging/leakage
