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 board 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 board by default.
There is reinforced insulation between the motor thermistor connection, the relay
output and the drive control board interface. Thus, you can connect a motor
thermistor to the drive through the extension module.
Note: In frames R5...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 board.
WARNING!
control board is powered using an external 24 V AC supply.
Do not connect the +24 V AC cable to the control board ground when the
