3-19 Jog Speed
Range:
Function:
150 RPM
*
[0 - par. 4-13 RPM]
Enter a value for the jog speed n
JOG
, which is a fixed output speed. The frequency converter runs at this speed
when the jog function is activated. The maximum limit is defined in par. 4-13
Motor Speed High Limit (RPM
).
See also par. 3-80.
2.6.4. Ramps
3-4* Ramp 1
For each of four ramps (par. 3-4*, 3-5*, 3-6* and 3-7*) configure the ramp parameters: ramp type, ramping times (duration of acceleration and decel-
eration) and level of jerk compensation for S ramps.
Start by setting the linear ramping times corresponding to the figures.
If S-ramps are selected then set the level of non-linear jerk compensation required. Set jerk compensation by defining the proportion of ramp-up and
ramp-down times where acceleration and deceleration are variable (i.e. increasing or decreasing). The S-ramp acceleration and deceleration settings are
defined as a percentage of the actual ramp time.
3-40 Ramp 1 Type
Option:
Function:
Select the ramp type, depending on requirements for acceleration/deceleration.
A linear ramp will give constant acceleration during ramping. An S-ramp will give non-linear acceleration, com-
pensating for jerk in the application.
