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

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

Common
to input/

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
