You have two options for the Control Unit power supply:
● External supply via terminals 31 and 32 with 20.4 V ... 28.8 V DC.
● Internal supply from the power module.
The summation of all currents of the following interfaces is limited to 0.8 A:
– Encoder power supply
– DRIVE-CLiQ
– Power supply for the Operator Panel
– Analog outputs
– 24 V output voltage (terminal 9)
– 24 V PROFIBUS teleservice
– Resolver excitation
