- 1
Verify drive parameters related to deceleration time (e.g., P2-xx) and braking resistor operation (e.g., P6-xx series) against application requirements and specifications.
- 2
Inspect the external braking resistor (if installed) and its wiring connections to the drive terminals (+1/+2) for any damage, loose terminals, or signs of overheating.
- 3
Measure the resistance value of the external braking resistor (with power off and discharged) and compare it against the specified ohmic rating.
- 4
Observe the mechanical load and deceleration profile during operation to identify excessive inertia or overly aggressive deceleration rates causing regenerative conditions.
