Process and Application Parameters [300]
144
determined by the parameter motor speed [225]. The maximum speed will
operate as an absolute maximum limit.
This parameter is used to prevent damage due to high speed.

Sync Speed
1-24000rpm

Note It is not possible to set the maximum speed lower than the minimum speed.
Note Maximum Speed [343] has priority over Min Speed [341], i.e. if [343] is set
below [341] then the drive will run at [343] Max Speed with acceleration times
given by [335] and [336] respectively.
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 VSD 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. 76 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.
