Skip frequency 1 (entered in Hz)	0.00 Hz	fout
Defines skip frequency 1, which avoids
effects of mechanical resonance and
suppresses frequencies within +/- p1101
(skip frequency bandwidth).

Skip frequency 2	0.00 Hz
Skip frequency 3	0.00 Hz				p1101
Skip frequency 4	0.00 Hz				Skip frequency

0	Continuous smoothing	The rounding times are recommended as
1	Discontinuous smoothing
		abrupt responses can be avoided therefore
		reducing stress and damage to the mechanical
		system.
		The ramp-up and ramp-down times are
		extended by the component of the rounding
		ramps.
OFF3 ramp-down time			5.00 s

Defines ramp-down time from maximum frequency to standstill for OFF3 command.
