Instruction manual

Note: 1. When selecting frequency reference from the control circuit terminal
FR as the target or feedback value, the V-I switch of SW2 on the con-
trol circuit board must be selected depending on the input method
(current or voltage input).
2. Never use the frequency reference from the control circuit terminal
FR for both the target and feedback values. The frequency reference
for both the target value and the feedback value becomes the same.
(Example)
When the frequency reference from the control cirucit terminal FR,
with a voltage of 0 to 10 V, is selected as the target value and n004=2,
and when at the same time the frequency reference from the control
circuit terminal FR, with a current of 4 to 20 mA, is selected as the
feedback value and n164=1, the feedback value will be set as the fre-
quency reference from the control circuit terminal FR with a voltage
of 0 to 10 V.
3. When using an analog signal (0 to 10 V/4 to 20 mA) input to the CN2
terminal of the JVOP-140 Digital Operator as the target or feedback
value of PID control, do not use it as a multi-function analog input.
Constant n077 (Multi-function Analog Input Function) must be set to
0 (disabled in this case).
