Group 22: Accel/Decel
Two acceleration/deceleration ramp pairs can be used. If both ramp pairs are
used, selection can be made between these in run time through a digital
input. The S curve of the ramps is adjustable.
Figure 6 Definition of acceleration/deceleration ramp time.
Code Description
2201 ACC/DEC 1/2 SEL
Selects the source for the ramp pair selection signal.
0 =
NOT SEL
The first ramp pair is used (ACCELER TIME 1/DECELER TIME 1).
1...5 = DI1...DI5
Ramp pair selection is done through a digital input (DI1 to DI5).
Digital input deactivated = Ramp pair 1 (
ACCELER TIME 1/DECELER TIME 1) is
used.
Digital input activated = Ramp pair 2 (
ACCELER TIME 2/DECELER TIME 2) is used.
Note! Ramp pair selection is not followed under serial link control.
2202 ACCELER TIME 1
Ramp 1: time from zero to maximum frequency (0 -
MAXIMUM FREQ).
2203 DECELER TIME 1
Ramp 1: time from maximum frequency to zero (
MAXIMUM FREQ - 0).
2204 ACCELER TIME 2
Ramp 2: time from zero to maximum frequency (0 -
MAXIMUM FREQ).
2205 DECELER TIME 2
Ramp 2: time from maximum frequency to zero (
MAXIMUM FREQ - 0).
2206 RAMP SHAPE

1 = FAST S CURVE
2 = MEDIUM CURVE
3 = SLOW S CURVE
