MICROMASTER 440 Operating Instructions
200 6SE6400-5AW00-0BP0
♦ In order that the motor can immediately establish a torque after an ON
command, the magnetizing time P0346, determined with the quick
commissioning, may not be reset. This is the reason that parameter P0346
should be checked for the weight equalization.
Typical magnetizing times for 4-pole 1LA7 motors are:
0.12 kW 50 ms 7.50 kW 300 ms
1.50 kW 100 ms 55.0 kW 700 ms
5.50 kW 250 ms
♦ The min. frequency P1080 should approximately correspond to the rated
motor slip (P1080
≈ r0330[Hz])
♦ In addition, the voltage boost should be adapted:
− V/f mode (P1300 = 0 ... 3)
- constant voltage boost P1310 ≈ 90 % (empirical value)
- voltage boost when accelerating
P1311
≈ 50 % (empirical value)
− SLVC mode (P1300 = 20)
- constant torque boost P1610 ≈ 90 % (empirical value)
- torque boost when accelerating
P1611
≈ 50 % (empirical value)
