9000: Heatsink temperature sensor: Overtemperature - Movement stopped

Info: Temperature limit
Data type: REAL

Description:
Runtime error if the temperature of the heat sink temperature sensor TEMP_HEATSINK exceeds the limit (see INFO).

Reaction:
The 'controller ready' state is reset.
When 'switch on controller' command: See error number 4005.

8V, 8BVI, 8CVI, 80V, 8DI:
Default setting STOP_ERR_DECEL_RAMP=ncA_LIMIT:
When position control is active (CONTROLLER_MODE=1 or 3):
Movement stopped with the axis limits and by switching off the controller.
When speed control is active (CONTROLLER_MODE=2):
Movement stopped with speed regulated ramp, with axis limits and by switching off the controller.
When U/f control is active (CONTROLLER_MODE=7):
Movement stopped with speed controlled ramp, with axis limits and by switching off the controller.
When current control is active with commutation (CONTROLLER_MODE=4):
Movement stopped with the current limits and by switching off the controller.

Setting STOP_ERR_DECEL_RAMP=ncINDUCTION:
Independent of controller mode: Movement is aborted with induction stop. See also error number 9001.

Setting STOP_ERR_DECEL_RAMP=ncCTRL_OFF:
Independent of controller mode: Movement is aborted by switching off the controller and the power section immediately. The drive has no electrical torque.

8B0P:
The chopper output and the CR_OK output are switched off, the main relay is opened and the RDY-, RUN- and ERR LEDs flashes synchonous in 3 seconds cycle. The error condition can only be exited by switching off the mains supply.

8BVP:
The IGBT power stage is switched off.

Cause/Remedy:
Invalid operational conditions:
- Environmental temperature is higher than 40C while in operation. -> Check the cool air temperature right after opening the intake.
- Moderate air flow in the ACOPOS servo drive. -> Check the mounting direction and the covers on the intake opening.

ACOPOS servo drive defect:
-Cooling fan defect. -> Check if the fan makes any sound when the controller is on. The sound from the fan is louder when the heat sink temperature is high.
- Problem with heat sink temperature measurement: -> When the controller is switched off, compare the environmental temperature with the temperature of the heat sink temperature sensor TEMP_HEATSINK.
- If the thermal transition resistance between IGBT and the heat sink is too high, check the heat dissipation past between the heat sink and IGBT. -> Switch the ACOPOS servo drive.
