Chapter 4 - Parameter Description [DRV]
37
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.

Note: The inverter will not reset when H/W fault occurs.
Repair the fault before turning on the power.
☞ Note: When multiple faults occur, only the highest-level fault
will be displayed.
