Commercial Power Switching Frequency Hold Time
Program ⇒ Terminal Selection Parameters ⇒ Line Power Switching
This parameter determines the amount of time that the connection to
commercial power is maintained once the switch-to-drive-output criteria has
been met.
Direct Access Number — F358
Parameter Type — Numerical
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 motor-control feedback.
Settings:
PID Control Disabled
VI/II
RR
RX
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 — 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 — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Proportional (P) Gain
Program ⇒ Feedback Parameters ⇒ Feedback Settings
This parameter provides a value that either increases or decreases 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 — Yes
Minimum — 0.01
Maximum — 100.0
