Description
Sets the internal frequency refer-
e ces ences.
* These frequency references are
selected with multi-step speed ref- selected with multi step speed ref
erences (multi-function inputs).
See the reference pages for the g
relationship between multi-step fre- relationship bet een m lti step fre
quency references and frequency
references. references
Selects the PID control method.
0: PID control disabled.
1 to 8: PID control enabled.
* The derivative control method (i.e.,
the derivative control of the devi-
ation or detected value), the addi-
tion of the frequency reference,
and the positive or negative char-
acteristics of PID control are
selectable.
Sets the value by which the feedback
value is multiplied.
* This parameter is used for adjust-
ing the target and detected values
so that they will have the same
input level.
Sets the proportional (P) gain for PID
control.
* PID control is disabled with this
parameter set to 0.0.
Sets the integral (I) time for PID con-
trol.
* Integral control is disabled with this
parameter set to 0.0.
Sets the derivative (D) time for PID
control.
* Derivative control is disabled with
this parameter set to 0.0.
This parameter is for the offset adjust-
ment of all PID control.
Sets the parameter as a percentage
based on the maximum frequency as
100%.
