Skip Speed 1 Low [344]
Within the Skip Speed range High to Low, the speed cannot
be constant in order to avoid mechanical resonance in the
AC drive system.
When Skip Speed Low ≤ Ref Speed ≤ Skip Speed High, then
Output Speed=Skip Speed HI during deceleration and
Output Speed=Skip Speed LO during acceleration. Fig. 104
shows the function of skip speed hi and low.
Between Skip Speed HI and LO, the speed changes with the
set acceleration and deceleration times. Skipspd1 LO sets
the lower value for the 1st skip range.
Fig. 104 Skip Speed.
Skip Speed 1 High [345]
Skipspd1 HI sets the higher value for the 1st skip range.
Skip Speed 2 Low [346]
The same function as menu [344] for the 2nd skip range.
Skip Speed 2 High [347]
The same function as menu [345] for the 2nd skip range.
Jog Speed [348]
The Jog Speed function is activated by one of the digital
inputs. The digital input must be set to the Jog function
[520]. The Jog command/function will automatically
generate a run command as long as the Jog command/
function is active. This is valid independent of settings in
menu [215]. The rotation is determined by the polarity of
the set Jog Speed.
Example
If Jog Speed = -10, this will give a Run Left command at
10 rpm regardless of RunL or RunR commands. Fig. 105
shows the function of the Jog command/function.
