809 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.
Acknowledgement not required
Stop response STOP VII
814 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
another quickly.
– Check whether the motor output is sufficient for the drive, otherwise
use a higher output motor, possibly in conjunction with a higher-rating
power section.
– Check the motor data. The motor current could be too high due to
incorrect motor data.
– Check the temperature sensor.
– Check the motor fan.

Stop response STOP VII
815 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
of the drive modules
– Avoid many acceleration and braking operations which follow quickly
one after the other
– Check that the power section for the axis/spindle is adequate,
otherwise use a higher-rating module
– Ambient temperature too high (refer to the Configuration Manual)
– Permissible installation altitude exceeded (refer to the Configuration
Manual)
– Pulse frequency too high (refer to the Configuration Manual)
– Check fan, if required, replace
– Maintain the minimum clearance above and below the power section
(refer to the Configuration Manual)
