External Control
6.8.1
Overview and Precaution of External Control
The settings in each operation mode normally use the internal reference signal. In
external control, this reference signal is supplied externally. The external signal is
either voltage (voltage control) or resistance (resistance control).
External control can control the settings from 0 % to 100 % of the selected range in
the CC, CR, CP, or CV mode.
Table 6-6
External control using voltage or resistance
There are other external controls as indicated below.

Control method
Operation mode
Description
Voltage
CC, CP, CV
Change of 0 V to 10 V produces a change of 0 % to
100 % of the rated value of the range
CR
Change of 0 V to 10 V produces a change of maxi-
mum value to minimum value of the range
Resistance
(proportional)
CC, CP, CV
Change of 0
Ω
to 10 k
Ω
produces a change of 0
% to 100 % of the rated value of the range
CR
Change of
0
Ω
to
10 k
Ω
produces a change of
maximum value to minimum value of the range
Resistance
(inverse proportional)
CC, CP, CV
Change of 10 k
Ω
to 0
Ω
produces a change of 0 % to
100 % of the rated value of the range
CR
Change of 10 k
Ω
to 0
Ω
produces a change of maxi-
mum value to minimum value of the range
