By way of the parameter channel all parameters of the drive unit can be
addressed. These transfers are processed at a lower priority level in the
drive unit.
Access to parameters is possible irrespective of the system status (see
Control and reference input) and definition of the control location (260-
CLSEL) and the reference channel (280-RSSL1). If the device baud rate
and address match, after initialization of the device parameters can be
queried and written.
