Operation mode speed controller, parameter
Operation mode
440 = 4
This operation mode is suited for speed controls with an analog actual value trans-
mitter (e.g. analog speedometer via analog input or HTL encoder via frequency in-
put).
The motor is accelerated or decelerated according to the control deviation.
The output frequency is limited by the
Maximum frequency
419.
NOTE
Minimum Frequency
418 is not limiting in mode "4-Speed". This can lead to a long
time operation of the motor in the current injection (current frequency <624 cutoff
frequency) in configurations 411 and 611. Prevent an impermissible motor tempera-
ture rise through to long operation in the current injection.
The operating mode "4-speed controller" can lead to a reversal of the drive.
