Figure 172: Compensating controller for acceleration
If the speed ramp was set too steep at a high load torque, it can happen that the drive
cannot be accelerated furthermore. In this case the frequency can be reduced at a con-
stant frequency (bit 7 of
Z
166.1
–
) to enable the drive acceleration.
3.8.9.2 Current control
If a specified torque is required to operate at low frequencies the current control at low
frequencies (bit 3 of
Z
166.1
–
) is recommended. An additional voltage (
Z
166.20
–
) is ap-
plied at the set frequency threshold (
Z
166.17
–
) via a PI controller, so that at least the set
current (
Z
133.22
–
) or maximum current (settable via bit 8 of parameter
Z
166.1
–
) is ap-
plied to the motor.
