Changeover speed
Remark
Configure two MDS.
Configure two DDS.
The MDS are assigned to the DDS.
Changeover to delta connection after speed in
p2155 is exceeded.
Identical numbers signify the same thermal
model.
Assigning the bit from r0830 to the MDS. If
p0827[0] = 1, for example, bit r0830.1 is set when
MDS0 is selected via DDS0.
The digital outputs for the contactors are assigned
to the bits.
The digital inputs for the feedback signal of the
motor contactors are assigned.
The drive controls the contactor circuit and pulse
inhibition. Parking bit (Gn_ZSW14) is set.
Sets the speed at which the circuit is to be
changed over to delta.
Note:
Using p2140, you can define an additional
hysteresis for the changeover (refer to function
diagram 8010 in the SINAMICS S120/150 List
Manual).
