Function
group 2
Motor rpm can be monitored in rPM.
When H40 is set to 0 {V/F control} or 1 {PID control}, the Inverter output frequency (f) is displayed in
RPM using the formula below. Motor slip is not considered.
H31 : Enter the number of rated motor poles on the nameplate.
H74 : This parameter is used to change the motor speed display to rotating speed
(r/min) or mechanical speed (m/mi).
