Activation of the temperature sensing
With p0600[0...n] = 11, motor temperature sensing via a Motor Module is activated.
Setting the temperature sensor
The temperature sensor type is set using p0601[0...n]. When connecting a temperature
sensor to terminal X41 of a chassis unit, you must specify to which power unit the
temperature sensor is to be connected when power units are connected in parallel. The
desired power unit is connected via p0602.
Note
Bimetallic NC contact is only possible for booksize formats
Temperature sensing using a bimetallic NC contact is only possible with Motor Modules in
the booksize format.
Note
PT100 is only possible for the chassis format
Temperature sensing using a PT100 is only possible with Motor Modules in the chassis
format.
If r0192.15 = 1 is displayed, then the PT 100 temperature sensor type can be selected with
p0601[0...n] = 5.
A motor temperature offset can be set using p0624 [0...n].
Power Module chassis
A Power Module in the chassis format has one temperature channel and can evaluate PTC,
KTY84, PT1000 and PT100 temperature sensors (r0192.15 = 1).
