Feedback Source
Program Feedback Parameters Feedback Settings
This parameter Enables/Disables PID feedback control. When enabled, this
parameter determines the source of the motor-control feedback.
Settings:
0 — PID Control Disabled
1 — VI/II
2 — RR
3 — RX
4 — RX2 (option)
Proportional-Integral-Derivative (PID) — A closed-loop control technique
that seeks error minimization by reacting to three values: One that is
proportional to the error, one that is representative of the error, and one that is
representative of the rate of change of the error.
Direct Access Number — F360
Parameter Type — Selection List
Factory Default — Control Disabled
Changeable During Run — Ye s
Feedback Source Delay Filter
Program Feedback Parameters Feedback Settings
This parameter determines the delay in the ASD output response to the motor-
control feedback signal
(signal source is selected at F360).
Direct Access Number — F361
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Ye s
Minimum — 0
Maximum — 255
Proportional (P) Gain
Program Feedback Parameters  Feedback Settings
This parameter determines the degree that the Proportional function affects the
output signal. The larger the value entered here, the quicker the drive responds
to changes in feedback.
Direct Access Number — F362
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Ye s
Minimum — 0.01
Maximum — 100.0
Integral (I) Gain
Program Feedback Parameters Feedback Settings
This parameter determines the degree that the Integral function affects the
output signal. The smaller the value here, the more pronounced the effect of the
integral function on the output signal.
Direct Access Number — F363
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Ye s
Minimum — 0.01
Maximum — 100.0
Upper Deviation Limits
Program Feedback Parameters Feedback Settings
This parameter determines the maximum amount that the feedback may
increase the output signal.
Direct Access Number — F364
Parameter Type — Numerical
Factory Default — 50.00
Changeable During Run — Ye s
Minimum — 0.00
Maximum — 50.00
