Changeover speed
Settings
Configure 2 MDS.
Configure 2 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 circuit is to be changed
over to delta.
Note:
Using p2140, you can define an additional
hysteresis for the changeover (refer
to SINAMICS S120/150 List Manual, function
diagram 8010).
