Actions
Depending on the topology, the following actions must be performed on the TM120:
1. TM120 between the Motor Module and the SMx Sensor Module
This TM120 evaluates four KTYs => sensor types must be selected by Servo-p4610/TM-
p4100. The associated temperature is output by servo-r4620/TM120-r4105.
2. TM120 directly on the Line Module
This TM120 evaluates four PTCs => sensor types must be selected by TM-p4100. The
associated temperature is output by servo-r4105.
Setting the threshold values in the PTC context:
– TM120-p4102[x]=251 => evaluation Off
– TM120-p4102[x]=120 => evaluation On
Assignment of the alarms to the motor
The occurring error messages are assigned to the motors as follows:
● Temperature channel on the TM120 in series connection with Motor Modules and encoders:
Alarm 207015 <location>drive: Motor temperature sensor warning
Alarm 207016 <location>drive: Motor temperature sensor fault
Alarm 235920 <location>TM: Temperature sensor channel 0 error
In this case, the output message with reference to the motor and to the temperature
component shows the relevant motor.
● Temperature channel on the TM120 directly to the Line Module:
Alarm 235207 <location>TM: Temperature fault/alarm threshold channel 0 exceeded
Special feature with PTC:
TM120-r4105 = -50 temperature is below the nominal response temperature
TM120-r4105 = 250 temperature is above the nominal response temperature
In this case, a message is output only with reference to the temperature component.
The affected motor can be determined from the information concerning the TM120.
