+ CAMH: MOTOR HEATER CONTROL
With this option, you can control the supply for the motor anti-condensation heater. The
external supply is connected to terminals -XD1.1 that are located in the lower part of the
cabinet. When the drive is not in Run state, the control relay +QAM changes the external
supply to the output terminals (-XDN). When the drive is in Run state, the control relay
disconnects the external supply to the motor heater. To disable the function, open the MCB –
FCN.
The control relay +QAM uses the GND (-XD2:13) and relay RO1 (-XD2:21) terminals.
The requirements: +CAPU Auxiliary AC supply terminals and +CAPD 24 VDC power supply

disconnects the supply to the cabinet heater. To disable the function, open the MCB –FCE.
The control relay +QAM uses the GND (-XD2:13) and relay RO1 (-XD2:21) terminals.
