Basic information about the drive system
12.2 Data sets
If several motors are operated alternately on a Motor Module, a matching number of drive
data sets must be created. For further information about motor changeover, see the "Motor
changeover" section in the Function Manual.
One drive object can manage up to 16 motor data sets. The number of motor data sets in
p0130 must not exceed the number of drive data sets in p0180.
For the 611U interface mode (p2038 = 1), the drive data sets are divided into groups of eight
(1-8; 8-16;...). Within a group, the assignment to the motor data set must be identical:
p0186[0] = p0186[1] = ... = p0186[7]
p0186[8] = p0186[9] = ... = p0186[15]
p0186[16] = p0186[17] = ... = p0186[23]
p0186[24] = p0186[25] = ... = p0186[31]
If this rule is not observed, alarm A07514 is output. If you need a precise representation of
the data set structure of the 611U, 32 drive data sets and 4 motor data sets must be
configured.
