Emotron AB 01-3694-01r2 Functional Description 87
Example
A conveyor belt is used to transport bottles. The required
bottle speed needs to be within 10 to 100 bottles/s. Process
characteristics:
10 bottles/s = 150 rpm
100 bottles/s = 1500 rpm
The amount of bottles is linearly related to the speed of the
conveyor belt.
Set-up:
Process Min [324] = 10
Process Max [325] = 100
Ratio [326] = linear
F(Value), ProcMin [327] = 150
F(Value), ProcMax [328] = 1500
With this set-up, the process data is scaled and linked to
known values which results in an accurate control.

Acceleration Time [331]
The acceleration time is defined as the time it takes for the
motor to accelerate from 0 rpm to nominal motor speed.
Communication information
Fig. 72 shows the relationship between nominal motor
speed/max speed and the acceleration time. The same is
valid for the deceleration time.
Fig. 72 Acceleration time and maximum speed
Fig. 73 shows the settings of the acceleration and decelera-
tion times with respect to the nominal motor speed.

Deceleration Time [332]
The deceleration time is defined as the time it takes for the
motor to decelerate from nominal motor speed to 0 rpm.
NOTE: If the Acc Time is too short, the motor is
accelerated according to the Torque Limit. The actual
Acceleration Time may then be longer than the value
set.
