Jog Stop Control	Direct Access Number —	F261
Program ⇒ Frequency Setting Parameters ⇒ Jog Settings	Parameter Type — Selection List
This parameter sets the stopping method used while operating in the Jog mode.	Factory Default — Deceleration Stop

frequency of the drive will accelerate to the upper level of the Jump
Frequency range and continue upward as programmed.
During deceleration, the output frequency of the drive will hold at the
frequency of the upper level of the Jump Frequency range until the
programmed deceleration ramp reaches the lower level of the Jump Frequency
range. Then, the output frequency of the drive will decelerate to the lower level
of the Jump Frequency range and continue downward as programmed.
Once set up and enabled, it is on in all control modes.
User-selected frequencies may be jumped to avoid the negative effects of
mechanical resonance.
Jump Frequency #1 Bandwidth	Direct Access Number —	F271
Program ⇒ Special Control Parameters ⇒ Jump Frequencies	Parameter Type — Numerical
	Factory Default — 0.00

This parameter establishes a plus-or-minus value for Jump Frequency #1 (see

F270).

Changeable During Run — Yes

Minimum — 0.00

Maximum — 30.00

Units — Hz

Jump Frequency #2

Program ⇒ Special Control Parameters ⇒ Jump Frequencies

Same as Jump Frequency #1 (F270) and is used when multiple frequencies are to be jumped (see the plus-or-minus value setting at F273). When multiple jump frequencies overlap, the system will recognize the lowest and the highest frequencies as one jump range.

Direct Access Number — F272

Parameter Type — Numerical

Factory Default — 0.00

Changeable During Run — Yes

Minimum — 0.00

Maximum — Max. Freq. (F011) Units — Hz

Jump Frequency #2 Bandwidth	Direct Access Number — F273
Program ⇒ Special Control Parameters ⇒ Jump Frequencies	Parameter Type — Numerical
This parameter establishes a plus-or-minus value for Jump Frequency #2	Factory Default — 0.00
	Changeable During Run — Yes
(F272).
	Minimum — 0.00
	Maximum — 30.0
	Units — Hz
