Table 8- 34 Parameters for switching the drive data sets:
Parameter
Description
p0820[0…n]
Drive data set selection DDS bit 0
If you use several command data sets
CDS, then you must set this parameter
for each CDS. The parameters are
assigned to a CDS through their index:
CDS0: p0820[0], p0821[0]
CDS1: p0820[1], p0821[1]
…
p0821[0…n]
Drive data set selection DDS bit 1
p0826
Motor changeover, motor number
Each drive data set is assigned a motor number:
p0826[0] = motor number for drive data set 0.
…
p0826[3] = motor number for drive data set 3.
If you operate the same motor with different drive data sets, then you must enter the
same motor number in every index of parameter p0826. In this particular case, you
can also switch over between the different drive data sets in operation.
If you operate different motors on one inverter, then you must number the motors in
parameter p0826. In this case, you may only switch over the drive data sets in the
"ready for operation" state with the motor switched-off. The switchover time is
approx. 50 ms.
