This chapter describes how to install and start up the optional CMOD-02 multifunction
extension module. The chapter also contains diagnostics and technical data.

Product overview

The CMOD-02 multifunction extension module (external 24 V AC/DC and isolated PTC
interface) has a motor thermistor connection for supervising the motor temperature
and one relay output, which indicates the thermistor status. In case the thermistor
overheats, the drive trips on motor overtemperature. If Safe torque off tripping is
required, the user must wire the overtemperature indication relay to the certified Safe
torque off input of the drive.
In addition, the extension module has an external power supply interface, which can
be used to power up the drive control unit in case the drive power supply is not on. If
you do not need the back-up power supply, you do not have to connect it because the
module is powered from the drive control unit by default.
There is reinforced insulation between the motor thermistor connection, the relay
output and the drive control unit interface. Thus, you can connect a motor thermistor
to the drive through the extension module.
With CCU-24 control unit, a CMOD-02 module is not necessary for external 24 V AC/DC
supply connection. The external supply is connected directly to terminals 40 and 41
on the control unit.
