Chapter 4 - Parameter Description [DRV]

This code display the motor speed in RPM during the motor is running.

Use the following equation to scale the mechanical speed using FU2-74 [Gain for Motor Speed display] if you want to change the motor speed display to rotation speed (r/min) or mechanical speed (m/min).

Motor Speed = 120 * (F/P) * FU2-74

Where, F: output frequency and P: the number of motor poles

DRV-10: DC Link Voltage

This code displays the DC link voltage inside the inverter.

DRV-11: User Display Selection

This code display the parameter selected in FU2- 73 [User Display]. There are 3 types of parameters in FU2-73 (Voltage, Watt and Torque).

DRV-12: Fault Display

This code displays the current fault (trip) status of the inverter. Use the [FUNC], [▲] and [▼] key to check for fault content(s), output frequency, output current, or whether the inverter was accelerating, decelerating, or in constant speed at the time the fault occurred. Press the [FUNC] key to exit. The fault content will be stored in FU2-01

to FU2-05 when the [RESET] key is pressed.
