Set one of the above values when using PID control.
The following table shows how to determine the target value and the
feedback value to be input when PID control is enabled.
Note: 1. When selecting a frequency reference from the control circuit termi-
nal 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 fre-
quency reference from the control circuit terminal FR with a voltage
of 0 to 10 V.

When LOCAL mode is selected, the target

When multi-step speed references are se-
lected, the currently selected frequency
reference will be the target value.
