Chapter 6 - Parameter Description [DRV]
6-5
I
Apply the frequency reference
(4~20mA) to the “I” control terminal.
Refer to the I/O-06 to I/O-10 for
scaling the signal.
1+I
Apply the frequency reference
(0~12V, 4~20mA) to the “V1”,“I”
control terminals.
The ‘V1’ signal overrides the ‘I’
signal. See I/O-01~10.
PULSE
Set the freq command using “A0, B0”
terminals. Range: 0~100kHz. See I/O-
11~16.
Int. 485
Set the freq command using RS485
communication. See I/O-90~93.
Ext. PID
Set APP-80 [Ext PI Mode] to “Yes.”
Apply Ext. PID feedback value
“4~20mA” to control terminal “I”. Set
one of the I/O-20~27 to [Ext PID
Run]. Inverter starts Ext.PID operation
when the defined terminal is ON and
Ext.PID output value becomes inverter
command frequency. See APP-80~97
for details.
DRV-05 ~ DRV-07: Step Frequency 1 ~ 3
The inverter outputs preset frequencies set in these
codes according to the Programmable
Digital Input
terminals configured as ‘Speed-L’, ‘Speed-M’,
‘Speed-H’ and ‘Speed-X’. The output frequencies are
decided by the binary combination of M1~M8. The
frequency setting method of ‘Speed 0’ is decided by
DRV-04.
See I/O-21~27 description for Step Freq 4~7.

DRV-08: Output Current
This code displays the output current of the inverter
in RMS.
DRV-09: Motor RPM
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).
