f
M
Motor frequency. Output from the frequency converter. Output frequency is related to the shaft speed on motor depending on number of poles and slip frequency.
f
MAX
The maximum output frequency the frequency converter applies on its output. The maximum output frequency is set in limit par. F-16, F-17 and F-03.
f
MIN
The minimum motor frequency from frequency converter. Default 0 Hz.
