Drv-08: Output Current; Drv-09: Motor Speed; Drv-10: Dc Link Voltage; Drv-12: Fault Display - LG SV-iS5 Instruction Manual

Chapter 6 - Parameter Description [DRV]
Related Functions: I/O-12 to I/O-14 [Reference Inputs]
I/O-17 [Filtering Time Constant]
I/O-21 to I/O-21 [Step Frequency 4~7]
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.
☞ Note: The frequency setting method of ' Speed 0' is
decided by DRV-04.

DRV-08: Output Current

DRV? Current
08 0.0 A
Factory Default:
0.0 A
This code displays the output current of the inverter in
RMS.

DRV-09: Motor Speed

DRV? Speed
09 0rpm
Factory Default:
0rmp
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

DRV? DC link vtg
10 ----- V
Factory Default:
---- V
This code displays the DC link voltage inside the inverter.

DRV-11: User Display Selection
DRV? User disp
11 Out 0.0 V
Factory Default:
0.0 V
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

DRV? Fault
12 None
Factory Default:
None
This code displays the current fault (trip) status of the
inverter. Use the PROG,
? and ?
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.
