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
(H)/frequency (H), RX
reference point 2 (H)/frequency
(H).
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.
