Motor temperature To measure the motor temperature, a KTY 84 must be connected at pin 13 and
pin 25 of X15 to X20. The temperature value is ascertained at least once per
second. The maximum permissible motor temperature is taken from the
motor table.
As soon as the given temperature is exceeded, the blinking error message
MOTOR TEMPERATURE <AXIS> TOO HIGH appears and the drives are automatically
switched off.
Module 9165 Sample the current motor temperature
Appropriate measures can be taken before the motor reaches the maximum
temperature.

Temperature
measurement of
linear and
torque motors
Linear motors usually have a KTY and several PTC thermistors or
thermoswitches for temperature measurement.
The KTY is monitored by the control (NC). The temperature signal is conducted
to the control together with the encoder signals (X15 to X20). If the KTY is not
to be evaluated, this function must be deactivated over MP2220.x, MP2221.x
(see "Monitoring functions" on page 894).
Marker Value Meaning
M4203 0 No error
1 Control has no current controller
The PTC thermistors or thermoswitches must be galvanically isolated
and evaluated by the PLC.
The KTY requires double insulation to the motor windings, which must be
provided by the motor manufacturer. Otherwise, do not connect the KTY
to the control!
