134 HX7+ ASD Installation and Operation Manual
At-Frequency Powerline Switching
Program Terminal Selection Line Power Switching
When enabled (F354), 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.
Direct Access Number —  F355
Parameter Type — Numerical
Factory Default — 60.00
Changeable During Run — Ye s
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
ASD-Side Switching Wait Time
Program Terminal Selection 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.
Direct Access Number —  F356
Parameter Type — Numerical
Factory Default — (ASD dependent)
Changeable During Run — Ye s
Minimum — 0.01
Maximum — 10.00
Units — Seconds
Commercial Power Wait Time
Program Terminal Selection 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.
Direct Access Number —  F357
Parameter Type — Numerical
Factory Default — 0.62
Changeable During Run — Ye s
Minimum — (ASD dependent)
Maximum — 10.00
Units — Seconds
Commercial Power Switching Freq. Hold Time
Program Terminal Selection 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 — Ye s
