  • X13: 24 V DC digital inputs and outputs

  • X15 / X16: Encoder interfaces

7. Operation & Commissioning

• Local Control: Use DBG60B handheld keypad for parameter setting, manual operation and fault inquiry.

• PC Commissioning: Use MOVITOOLS® MotionStudio for programming, real-time monitoring and fault diagnosis.

• Available Modes: Jog mode, reference homing, positioning mode and synchronous operation.

8. Safety Instructions

• Only qualified electrical personnel are permitted to perform installation, wiring and commissioning work.

• High residual voltage remains inside the drive after power is cut off. Wait at least 5 minutes for full capacitor discharge before touching internal terminals.

• Apply shielded cables for motor and signal wiring, and use a qualified external EMC filter.

9. Maintenance & Troubleshooting

• Routine Maintenance: Regularly check cable connections and ventilation paths. Clean dust with dry compressed air.

• Common Faults: Overcurrent (OC), Overvoltage (OV), Overtemperature (OT) and Encoder Error. Fault codes can be checked via keypad or supporting software.

10. Typical Applications

• Conveyors, cranes and hoists
