Function:
Set the SSI clock rate. With long
encoder cables, the clock rate must be
reduced.
Function:
Set the data format of the SSI data.
Function:
NOTICE
This parameter cannot be adjusted while the
motor runs.
Select the baud rate of the attached encoder.
The parameter is only accessible when
parameter EC-20 Protocol Selection is set to [1]
HIPERFACE.
Function:
NOTICE
This parameter cannot be adjusted
while the motor runs.
Change the detected encoder rotation
direction without changing the wiring to
the encoder.
