DRV-00 Main Scree DRV-00 Parameter
When [Enter] key is pressed in DRV-00 screen the
display will enter programming mode for the
Command Frequency and a flashing cursor will be
displayed which can be moved with the [Shift] key.
When [Enter] key is pressed after the Command
Frequency number (Hz) has been changed, the
display will show DRV-00 screen with new speed
command. The DRV-00 screen will show actual
VFD output frequency instead of Command
Frequency when VFD starts running the motor.
If PID control is enabled, DRV-00 screen will
display PID set point while in stop mode and actual
output frequency while in run mode.
When DRV-24 is changed from Hz to RPM, the
DRV-00 screen will show Speed reference and
actual Speed in RPM.

The Step Frequencies are the preset speeds
activated by a binary coded combination of four
programmable digital inputs set to Speed-L, M, H,
and X in parameters I/O-20 ~I/O-27. The table
below shows all digital input combinations for the
15 possible preset speeds.

If any digital input I/O-
20~27 is programmed
to Jog_FX or Jog_RX and activated, the VFD will
run forward or reverse at DRV-16 Jog Speed based
on ACC or DEC time until input is disabled.

DRV-17 shows the actual motor current.
DRV-18 shows the actual motor speed.
DRV-19 shows the actual DC bus voltage
DRV-20 shows the actual VFD output voltage or
kW selected in FG2-81.
These parameters show actual (non-adjustable)
values and can be used for monitoring and trouble-
shooting purposes.

DRV-21 shows None
(VFD is ready) or the
current fault if VFD is tripped. It is possible to
check Hz, Amps, VFD mode and Trip time by
pressing [ENTER] key and then [UP] key for each
reading. When readings are checked, press
[ENTER] key to return to the fault display.

The Target value shows
what speed command
VFD should follow. The Output value shows the
actual VFD output speed. This parameter is very
useful for trouble-shooting.
