Chapter 6 - Parameter Description [DRV]

☞ Note: The frequency setting method of ‘Speed 0’ is
decided by DRV-04.
DRV-08: Output Current
This code displays the output current of the inverter in
RMS.
DRV-09: Motor Speed
This code displays the motor speed in RPM while 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 displays the parameter selected in FU2-73
[User Display]. There are 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 PROG, ? and ? key before pressing
the RESET key to check the fault content(s), output
frequency, output current, and whether the inverter was
accelerating, decelerating, or in constant speed at the
time of the fault occurred. Press the ENT key to exit.
The fault content will be stored in FU2-01 to FU2-05
when the RESET key is pressed. For more detail,
please refer to Chapter 7.

n I/O-01 to I/O-10: Scaling the analog input signals (V1 and I)
for frequency reference.
n I/O-17: Adjusts the response sensibility of the input terminal
to eliminate contact noise.
n I/O-21 to I/O-24: Sets the step frequency from 4 to 7.
