MG.33.B4.02 - VLT is a registered Danfoss trademark
to the fixed value from par. 3-14. The sum (called
Y in the illustration below) is multiplied with the
actual reference (called X below) and the result is
added to the actual reference (X+X*Y/100).
Par. 3-18 cannot be adjusted while the
motor is running.
3-19 Jog Speed [RPM]
Range:
0 - par. 4-13 RPM
Function:
The jog speed n is a fixed output speed.
JOG
The frequency converter runs at this speed
when the jog function is active.
Ramps
"
3-4* Ramp 1
Selection of ramp type, ramping times (acceleration
times and deceleration times) and setting of
percentage of jerk parts of S ramps.
Start by setting the linear ramping times
corresponding to figure and formulas.
If S-ramps are chosen then set the percentage of the
jerking part of acceleration and deceleration ramps.
