Emotron AB 01-3694-01r2 Functional Description 93
Fig. 78
Maximum Speed [343]
Sets the maximum speed at 10 V/20 mA, unless a user-
defined characteristic of the analogue input is programmed.
The synchronous speed (Sync-spd) is 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.
Communication information
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 Out-
put Speed=Skip Speed LO during acceleration. Fig. 79
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.
