Motor changeover sequence
1. Pulse suppression:
The pulses are suppressed following the selection of a new drive data set using p0820 to
p0824.
2. Open motor contactor:
Motor contactor 1 is opened (r0830 = 0) and the status bit "Motor changeover active"
(r0835.0) is set.
3. Change over drive data set:
The requested data set is activated (r0051 = data set currently effective, r0837 =
requested data set).
4. Energize motor contactor:
After the feedback signal (motor contactor opened) from motor contactor 1, the
appropriate bit of r0830 is set and motor contactor 2 is energized.
5. Enable pulses:
After the feedback signal (motor contactor closed) from motor contactor 2, the bit "motor
data set changeover active" (r0835.0) is reset and the pulses are enabled. The motor has
now been changed over.

Comment
Configure 2 MDS
Configure 2 DDS
The MDS are assigned to the DDS.
The digital input to change over the motor is selected via the
DDS. Binary coding is used (p0820 = bit 0, etc.).
Different numbers mean different thermal models.
The bits of r0830 are assigned to the MDSs. If p0827[0] = 0,
for example, bit r0830.0 is set via DDS0 when MDS0 is se-
lected.
The digital outputs for the auxiliary contactors are assigned to
the bits.
The digital inputs for the feedback signal of the motor contac-
tors are assigned.
The drive controls the contactor circuit and pulse inhibition.
