Notes: 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 control 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 circuit 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 frequency reference from the control
circuit terminal FR.
3. When using the analog signal (0 to 10V / 4 to 20mA) which inputs to the CN2
terminal of the digital operator JVOP-140 as the target or feedback value of
PID control, never use it as a multi-analog input. Parameter n077 (multi-
function analog input) should be set to 0 (disabled).
• Proportional gain (P), Integral time (I), Differential time (D)
(n130, n131, n132)
Adjust the response of the PID control with the proportional gain (P), intregal time (I),
and differential time (D).
Optimize the responsiveness by adjusting it while operating an actual load (mechanical
system). Any control (P, I, or D) that is set to zero (0.0, 0.00) will not operate.
