[Dwell Frequency]
This value sets the frequency that the drive will
immediately output (no Accel Ramp) upon a start
command.Thisparameterrequiresa programmed[Dwell
Time].
Parameter Number 43
Parameter Type Read and Write
Display Units / Drive Units 0.1 Hertz / Hertz x 10
Factory Default 0.0 Hz
Minimum Value 0.0 Hz
Maximum Value 7.0 Hz
[Dwell Time]
This value sets the time the drive will continue to output
[Dwell Frequency] before ramping to [Freq Command].
Parameter Number 44
Parameter Type Read and Write
Display Units / Units 1 Second / Seconds
Factory Default 0 Sec
Minimum Value 0 Sec
Maximum Value 10 Sec
[Speed Control]
Thisparameterselectsthetypeofspeedmodulationactive
in the drive.
This parameter cannot be changed while the drive is
running.
Important: “No Control” and “Phase Lock” are the only
available options for synchronous motors.
If encoder feedback closed loop speed regulation is
required, “Encoder Fdbk” must be selected.
Parameter Number 77

“No Control” 0 Frequency regulation
“Slip Comp” 1 Slip compensation
“Speed Droop” 2 Negative slip compensation
“Phase Lock” 3 Enable phase lock to pulse input
“Encoder Fdbk” 4 Encoder feedback-closed loop
“Droop + Reg” 5 Enc. fdbk.-closed loop w/ active
droop
“P Jump” 6 Traverse function
“Process PI” 7 Closed loop PI control
[Slip @ F.L.A.]
This value sets the amount of automatic increase or
