Description:
Runtime error when controller is active, if the DC bus voltage UDC_ACT exceeds the module-dependent limit voltage.

Reaction:
8Vxxxx.00-x, 8Vxxxx.50-x, 8BVI, 8CVI, 80V, 8DI:
If the DC bus voltage drops within the time AXLIM_T_STOP_END under the module-dependent limit voltage, then the movement is stopped with short-circuit braking without current limitation.
Setting STOP_ERR_DECEL_RAMP=ncCTRL_OFF:
Movement is aborted by switching off the controller and the power section immediately. The drive has no electrical torque.
Cause/Remedy:
See Power unit
Braking resistor not active:
In generator operation, check if the recorded DC bus voltage (UDC_ACT) does not level off when the switch-on voltage of the braking resistor (UDC_ACT > UDC_BLEEDER_ON) is exceeded.
- Control of the braking resistor is defective. -> Replace the ACOPOS module
- Relay bleeder (intern/extern) is defective. -> Replace the ACOPOS module
- Fuse for external braking resistor is defective. -> Check or switch the fuse
- Internal or external braking resistor is defective or is not connected. -> Replace the ACOPOS module or the braking resistor. Measure the braking resistance on the plug and compare with the data sheet. -> Check the wiring of the external braking resistor. Caution: Observe safety regulations.
- 8B0Pxxxxxxxx.xxx-x: Controller is not switched on
Mains disturbance:
- Supply voltage or DC bus voltage is too high. -> Check the DC bus voltage.
