613 Shutdown limit, motor overtemperature (P1607)
exceeded
Cause The motor temperature (sensed via the temperature sensor KTY 84
and fed to the module via the motor encoder cable) has exceeded the
temperature limit in P1607.
Remedy – Avoid many acceleration and braking operations which follow one
– Motor overload?
– Check whether the motor output is sufficient for the drive, otherwise
– Check the motor data. The current could be too high due to incorrect
– Check the temperature sensor.
– Check the motor fan.
– Check the motor encoder cable.
– Motor encoder defective?
– Check and possibly reduce P1230 or P1235.
The motor temperature monitoring can be disabled with
P1601 bit 13 = 1.
For linear motors:
– Check the parameters for the motor temperature monitoring
P1602 (alarm threshold, motor overtemperature) = 120 degrees C
P1603 (timer, motor temperature alarm) = 240 s
P1607 (shutdown limit, motor temperature) = 155 degrees C
P1608 (fixed temperature) = 0 degrees C
P1608 = 0 ––> Temperature sensing active
P1608 > 0 ––> Fixed temperature active
– If the temperature monitoring is exclusively realized using an external
– Check the power connector at the motor
– Check the connection of the temperature sensor coupling cable at the
