Run/stop setup
Run/stop operation by means of external
commands.
Setup of frequency setting signal and
running frequency characteristic
To set up frequency setting signal to be
input to the external signal (RX terminal)
and characteristic of running frequency.
Frequency characteristic is set up at the
two points of RX reference point 1

Connection and calibration of
frequency meter
Connect a 1mAdc full-scale DC current
meter, 7.5Vdc full-scale DC voltmeter or
rectifier type AC voltmeter.
For calibration of the meter, refer to the
Section 5.16.

*: Regardless of open/closed circuit between R and CC terminals, run and stop operation is
controllable.
Switching between forward run and reverse run is controllable by the terminals F/R and
RX if reverse run prohibition selection H is properly set up.
For details, refer to Section 6.14.4.
