Installation Steps

1. Power off the whole drive system completely

2. Insert 0-49040 card into designated CardPak slot

3. Fasten front panel fixing screws tightly

4. Confirm all bus connectors are fully inserted

5. Check power line and signal line wiring correctness

6. Power on after all inspection finished

Adjustment Method

1. No-load power on the drive device

2. Adjust panel potentiometer to set armature maximum voltage

3. Calibrate current feedback value according to motor parameters

4. Run motor with light load to test speed stability

5. Fine tune parameters to reach rated operating state

Operation Instruction

1. Normal Operation: Receive external speed signal, automatically adjust rectifier output voltage to control motor speed

2. Load Running: Automatically compensate voltage according to load change, keep stable torque output

3. Fault State: Automatically limit output current when overloaded, avoid drive and motor damage

4. Stop State: Cut off rectifier output quickly to stop motor operation

Compatibility

Daily Maintenance
