RR/S4 Input
SW3: Multifunction programmable analog input
terminal when SW3 is in the RR position.
Standard default setting:0~10Vdc input and
0~60Hz frequency.
10Vdc
(Internal impedance:30 k)
VI/I I Input
Multifunction programmable analog input.
Standard default setting: 0~10Vdc input and
0~60Hz frequency.
This terminal can also be used as a 4-20mAdc
(0-20mAdc) input terminal, if the parameter
H set to .

FM Output
Multifunction programmable analog output.
Standard default setting: output frequency
Use this terminal to connect a 1mAdc full-scale
ammeter. This terminal can also be used as a
0-10V (H=) or 0-20mA terminal
(H=), if the SW2 switch is set to
0-10V/0-20mA side.

OUT1
Output
Multifunction programmable open collector
output. The default setting is to output a signal
when output low speed threshold has been
reached. Depending on the SW4 setting,
pulses are output with frequencies of 1.00kHz
to 43.20kHz. Standard default setting:3.84kHz
Open collector output
24Vdc-50mA
*Sink logic/source
logic switchable
OUT2
Multifunction programmable open collector
output. By default, it is set to output a signal
indicating the completion of acceleration or
deceleration.
NO
Digital output signal equipotential (0V) terminal
for the control circuit. It is isolated from the CC
terminal.
CCA
*1
Common
to input/
output
Analog input/output signal equipotential (0V)
terminal for the control circuit.
- -
*1: Although the CC terminal and the CCA terminal are not insulated, they should be used separately, one for the logic circuit and
the other for the analog circuit
