Parking axis selected
Cause
When starting a traversing block or when starting referencing, the
"parking axis" function is selected.
Remedy
Cancel the "parking axis" function and then re-start the required func-
tion.

Motor temperature, pre-alarm
Cause
The motor temperature is sensed via a temperature sensor (KTY84)
and evaluated on the drive side. This alarm is output if the motor tem-
perature reaches the alarm threshold motor overtemperature (P1602).
Remedy
– Avoid many acceleration and braking operations which follow one
– Check whether the motor output is sufficient for the drive, otherwise
– Check the motor data. The motor current could be too high due to
– Check the temperature sensor.
– Check the motor fan.

Power module temperature, pre-alarm
Cause
The heatsink temperature of the power section is sensed using a ther-
mosensor on the main heatsink. If the overtemperature condition re-
mains, then the drive shuts down after approx. 20 s.
Remedy
Improve the drive module cooling, e.g. using:
– Higher airflow in the switching cabinet, possibly cool the ambient air
– Avoid many acceleration and braking operations which follow quickly
– Check that the power section for the axis/spindle is adequate,
– Ambient temperature too high (refer to the Configuration Manual)
– Permissible installation altitude exceeded (refer to the Configuration
– Pulse frequency too high (refer to the Configuration Manual)
– Check fan, if required, replace
– Maintain the minimum clearance above and below the power section
