Interface l Master-slave Operation of Drives Diagram.
The encoder interface can be used to link one or more drives together in a
master-slave operation, as shown in the following diagram. Up to 16 slave
drives can be controlled by a designated master drive via the encoder output.
The UniLink software allows you to setup the parameters for the slave drive(s)
and to adjust the gear ratio (number of pulses/turn).
Note: In this configuration, the analog setpoint inputs are disabled and Analog Com
and I/O Com (connector X3) must be connected.
