11.1 Operating status monitoring

Output current
Group Display Parameter Name Setting Range Default Unit
Drive group CUr [Output current] -

Inverter output current can be monitored in Cur.

Motor RPM
Group Display Parameter Name Setting Range Default Unit
Drive group rPM [Motor RPM] -
Function
group 2
H31 [Number of motor poles] - 2 ~ 12 4
H49 [PID control select] - 0 ~ 1 0
H74
[Gain for Motor rpm
display]
- 1 ~ 1000 100 %

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 motor poles shown on the motor nameplate.

H74: This parameter is used to change the motor speed display at run speed (r/min) or mechanical
speed (m/min).

Inverter DC Link Voltage
Group Display Parameter Name Setting Range Default Unit
Drive group

[Inverter DC Link
Voltage]
-

Inverter DC link voltage can be monitored in dCL.

2
times the value of input voltage is displayed in dCL while motor is at a stop.
