6.4 EXTENDED POWER MODULE (EPM)
The EPM’s receive control signals from the CPM. The signals are directed to either a stepper or
servo drive card which connects directly to a motor.
Positional information of the motor (acquired from sensors or encoders) is fed back to the CPM via
the ESIO modules.

NOTE
EPM 1 is only fitted if auto coplanarity or TCM option is fitted.
In the circuit diagrams and schematics, the driver card designation reflects the EPM number plus
the position of the card. For example:
●
EPM3-1 = the drive card in the top position of EPM 3
●
EPM3-2 = the drive card in the bottom position of EPM 3
