Description:
Runtime error when controller is active. The DC bus voltage monitor is registering that the module-dependent limit voltage has been exceeded.
8Vxxxx.00-x.. ~ 900VDC
8BVI, 8CVI.... ~ 900VDC (UDC_OVMON_CTRL_OFF_LIM)
8BVP, 8B0P... ~ 900VDC (UDC_OVMON_CTRL_OFF_LIM)
8DI......... ... ~ 900VDC (UDC_OVMON_CTRL_OFF_LIM)
8Vxxxx.50-x.. ~ 450VDC
80V............. ~ 95VDC (UDC_OVMON_CTRL_OFF_LIM)
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 transmission
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. -> Switch the ACOPOS servo drive
- Relay bleeder (intern/extern) is defective. -> Switch the ACOPOS servo drive
- Fuse for external braking resistor is defective. -> Check or switch the fuse
- Internal or external braking resistor is defective or is not connected. -> Switch the ACOPOS servo drive or the braking resistor. Measure the braking resistor on the ACOPOS servo drive X6 terminal and compare with the data sheet. -> Check the wiring of the external braking resistor. Caution: Observe safety regulations.
Recovery power limiter:
- switched off. -> Check if PLIM_MODE is set to 0.
- Incorrect configuration: Resistance of the external braking resistor R_BLEEDER_EXT is too high or stator resistance MOTOR_STATOR_RESISTANCE is too low.
Mains disturbance:
- Supply voltage or DC bus voltage is too high. -> Check the DC bus voltage.
