1249 External contactor control, motor changeover (ARM)
Min Standard
0 0
... 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.
1250 Frequency limit, act. current smoothing
Min Standard
0.0 100.0
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.
1251 Time constant (smoothing) motor utilization
Min Standard
0.0 10.0
Smoothing to display the motor utilization (P0604).
1252 Frequency limit, torque setpoint smoothing (ARM SRM)
Frequency limit, force setpoint smoothing (SLM)
Min Standard
0.0 100.0
PT1 filter for the torque setpoint display (smoothing for P1716, analog output of signal number
36).
Note:
< 1 Hz ––> the filter is inactive
This parameter has no effect on the closed-loop control.
1254 Time constant current monitoring
Min Standard
0.0 0.5
