This parameter determi nes the amount of tim e that the connectio n to
commercial power is mainta in e d onc e the switch-to-drive-ou tp ut cri te ria has
been met.
Direct Access Number — F358
Parameter Type — Numeri cal
Factory Default — 2.00
Changeable During Run — Yes
Minimum — 0.10
Maximum — 10.00
Units — Seconds
Feedback Source
Program ⇒ Feedback Parameters ⇒ Feedback Settings
This parameter Enables/Disables PID feedback control. When enabled, this
parameter determines the source of the m otor-control feedback .
Settings:
PID Control Disabled
VI/II

RX2 (option)
Proportional-Integral-Derivative (PID) — A closed-loop control technique
that seeks error min imization 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 — Yes
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 — Numeri cal
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Proportional (P) Gain
Program ⇒ Feedback Parameters ⇒ Feedback Settings
This parameter determines the degree that the Proportional function affects t he
output signal. The larger the value entered here, the quicker the drive responds
to changes in feedback.
Direct Access Number — F362
Parameter Type — Numeri cal
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.0
Integral (I) Gain
Program ⇒ Feedback Parameters ⇒ Feedback Settings
This parameter determ ines 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 — Numeri cal
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.0
