H9 ASD Installation and Operation Manual 147

Commercial Power/ASD Switch ing Frequency

Program ⇒ Terminal ⇒ Line Power Switching
When enabled at F354 and with a properly configured discrete output terminal,
this parameter sets the frequency at whi ch the At Frequency Powerline
Switching function engages.
The At Frequency Powerline Switching functio n commands the system to
discontinue using the output of the drive and to sw itch to commercial power
once reaching the frequency set here.
See parameter F354 for more information on this set ting.
Direct Access Number — F355
Parameter Type — Numeri cal
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 determi nes the amount of tim e that the drive will w ait 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 set ting.
Direct Access Number — F356
Parameter Type — Numeri cal
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 determi nes the amount of tim e that the drive will w ait before
allowing commercial power to be applied to the motor once the switch-to-
commercial-power cr iteria has been met.
See parameter F354 for more information on this set ting.
Direct Access Number — F357
Parameter Type — Numeri cal
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 determ ines the amount of tim e that the connection to
commercial power is mainta in e d onc e the switch-to-drive-ou tp ut cri te ri a has
been met.
See parameter F354 for more information on this set ting.
Direct Access Number — F358
Parameter Type — Numeri cal
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 use d 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 th is release)
Direct Access Number — F359
Parameter Type — Selection List
Factory Default — PID Off
Changeable During Run — No
