H9 ASD Installation and Operation Manual 147
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 drive 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 — 60.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
ASD-side Switching Wait Time
Program ⇒ Terminal ⇒ Line Power Switching
This parameter determines the amount of time that the drive will wait before
outputting a signal to the motor once the switch-to-drive-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 — 0.10
Maximum — 10.00
Units — Seconds
Commercial Power Switching Wait Time
Program ⇒ Terminal ⇒ Line Power Switching
This parameter determines the amount of time that the drive 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 — 0.62
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-drive-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 Control Switching
Program ⇒ Feedback ⇒ Feedback Settings
This parameter is used to set the PID control mode.
Selecting Process PID uses the upper and lower limit settings of parameters
F367 and F368.
Selecting Speed PID uses the upper and lower limit settings of parameters
F370 and F371.
Settings:
0 — PID Off
1 — Process PID
2 — Speed PID
3 — Easy Positioning PID (unavailable at the time of this release)
Direct Access Number — F359
Parameter Type — Selection List
Factory Default — PID Off
Changeable During Run — No
