Distances to User Devices
There are no distance limits for encoders or drives. Given the limits of
your power supply, you must calculate the maximum distance at
which the current requirements for the drive or encoder are met. In
these calculations you must allow for voltage drops over the length of
the cable. Refer to the cable manufacturer’s specifications to
determine the voltage drop in your cable.
Wiring Your User Devices
Use the wiring diagrams in Wiring Fast I/O and Estop and Wiring
Power Supplies, Encoders, and Drives to help wire your user devices
to the SLC Servo Module. Match the connector signals from the SLC
Servo Module with the signals on the connector blocks of the
termination panel. There is a one-to-one connection relationship
between these connectors (except for the Estop and drive enable
signals). Then follow the signals from these connector blocks to the
various user devices.
