Chapter 6 - Parameter Description [DRV]
6-6
DRV-17: Hz/Rpm Display
Set this parameter to [Hz] to display frequency, or to
[Rpm] to display speed on main display, DRV-00 and
other parameters with units of [Hz].
DRV-18: PID Parameter (To monitor PID controller’s
Reference/Feedback value and Drive’s
Command/Output frequency)
This parameter displays the PID controller’s reference
(set point) and the feedback value on the left side of the
display. It also displays the drive’s commanded and
output frequency. All values are displayed in Hz
(default), the feedback value will be displayed in
percent [%] unit.
DRV-19: AD Parameter (To monitor the AD
conversion value of Analog input)
This parameter displays the “raw” A to D (Analog to
Digital converter) values of the analog inputs used for
Freq mode, PID or Ext. PID reference/feedback. The
readings are in raw A/D “counts”. The A/D range is 0
to 4096 counts. Typically for a 0->10V input: 0V ~ 0
counts and 10V ~ 4096 counts.
Ex) When using V1 and I
DRV-20: EXT-PID Parameter
(To monitor ExtPID controller’s reference/ feedback/
output value)
Displays ExtPID controller’s reference/ feedback/
output value.
When APP-80 [Ext. PID operation selection] is set to
“YES,” reference and feedback are displayed in
Percent unit.
When the PI Feedback signal (APP-06) and units (I/O-
86) are selected, the reference and feedback values will
be displayed by percent [%] unit.
.
DRV-21 ~ DRV-23: Step Frequency 1 ~ 3
The drive outputs the preset frequencies set in these
parameters according to the programming and the state
of the multi-function terminals configured as ‘Speed-
L’, ‘Speed-M’, ‘Speed-H’ and ‘Speed-X’. The output
frequencies are determined from the binary
combination of M1~M3. The frequency setting method
of ‘Speed 0’ is determined by DRV-04.
See I/O-21~ 27 descriptions for Step Freq 4~7.
