Encoder emulation (master operation)
9.1.1
Function: Encoder emulation
During encoder emulation (master operation), the motor controller can output the current actual posi-
tion (rotor position) as incremental signals (A/#A/B/#B/N/#N) at the encoder output [X10]. The incre-
mental signals can be used by a connected slave device as synchronisation signals. Depending on the
cable length, up to 32 slave motor controllers can be controlled via the encoder output (synchronisa-
tion interface [X10]) of the master motor controller.
The incremental signals “A/#A/B/#B/N/#N” from the synchronisation inter-
face [X10/X10.1/X10.2] can either be used as an encoder input for synchronisation or as
an encoder output for encoder emulation (default setting).
