Diagram of
master-slave
operation
The encoder interface can be used to link one or more 17D HP drives together in a
master-slave operation, as shown in the following diagram. The UniLink software
allows you to setup the parameters for the slave drive(s).
Note: In this configuration, the analog setpoint inputs are disabled, a Analog Com
and I/O Com (connector X3) must be connected together.
Incremental
encoder
emulation
Note: Up to 16 slaves drives can be controlled by the master drive.
SSI encoder
emulation
Note: Only one slave drive can be controlled by the master drive.
