142 GX9 ASD Installation and Operation Manual
Commercial Power/ASD Switching Frequency
Program Terminal Line Power Switching
When enabled at F354 and with a properly configured discrete output terminal,
this parameter sets the frequency at which the At Frequency Powerline
Switching function engages.
The At Frequency Powerline Switching function commands the system to
discontinue using the output of the ASD and to switch to commercial power
once reaching the frequency set here.
See parameter F354 for more information on this setting.
Direct Access Number — F355
Parameter Type — Numerical
Factory Default — 60.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
ASD-Side Switching Waiting Time
Program Terminal Line Power Switching
This parameter determines the amount of time that the ASD will wait before
outputting a signal to the motor once the switch-to-ASD-output criteria has
been met.
See parameter F354 for more information on this setting.
Direct Access Number — F356
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — (ASD-Dependent)
Maximum — 10.00
Units — Seconds
Commercial-Power-Side Switching Waiting Time
Program Terminal Line Power Switching
This parameter determines the amount of time that the ASD will wait before
allowing commercial power to be applied to the motor once the switch-to-
commercial-power criteria has been met.
See parameter F354 for more information on this setting.
Direct Access Number — F357
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — (ASD-Dependent)
Maximum — 10.00
Units — Seconds
Commercial Power Switching Freq. Hold Time
Program Terminal Line Power Switching
This parameter determines the amount of time that the connection to
commercial power is maintained once the switch-to-ASD-output criteria has
been met.
See parameter F354 for more information on this setting.
Direct Access Number — F358
Parameter Type — Numerical
Factory Default — 2.00
Changeable During Run — Yes
Minimum — 0.10
Maximum — 10.00
Units — Seconds
PID Feedback Signal Selection
Program Feedback 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
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
