Hardware description

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. To trip the drive, the user must connect
this overtemperature indication back to the drive, for example, to its Safe torque off input.
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 fails. 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.
Note:
In frames R6...R9, you do not need a CMOD-02 module to use external 24 V AC/DC supply.
The external supply is connected directly to terminals 40 and 41 on the control unit.
WARNING!
Do not connect the +24 V AC cable to the control unit ground when the control
unit is powered using an external 24 V AC supply.
