... specifies whether the contactor control for the motor changeover is defined by the drive or
from an external control.
1
Motor changeover via external control
The contactor control for motor changeover is determined via an external control via the ”Motor
changed over” input signal (STW2.11).
=
Motor changeover via the drive
The contactor control for motor changeover is determined by the drive via output terminals with
function numbers 11, 12, 13 and 14.
Note:
refer to the index entry ”Motor changeover”
The contactors for motor changeover must be switched to a no-current condition. If motor
changeover is executed using an external control, and changed over with ”Fault” (e. g. with
drive pulses present), the power/supply infeed module could be destroyed.
Recommendation:
Change over the motor using the drive output terminals (P1249=0).
The output terminals 11, 12, 13 and 14 are not energized if P1249 = 1.

PT1 filter for the current actual value display
The parameter is used to smooth the following displays:
– P1708 (torque-generating current Iq)
– P1718 (torque-generating current Iq (A)), from SW 3.1
– PROFIBUS status word IqGl (smoothed, torque-generating current Iq) from SW 3.1
Note:
< 1 Hz ––> the filter is inactive
This parameter has no effect on the closed-loop control.
