Group 22: Accel/Decel
This group defines ramps that control the rate of acceleration and
deceleration. You define these ramps as a pair, one for acceleration
and one for deceleration. You can define two pairs of ramps and use a
digital input to select one or the other pair.
Code Description
2201 ACC/DEC 1/2 SEL
Defines control for selection of acceleration/deceleration ramps.
• Ramps are defined in pairs, one each for acceleration and
deceleration.
• See below for the ramp definition parameters.

2202 ACCELER TIME 1
Sets the acceleration time for zero to maximum frequency for ramp
pair 1. See A in figure.
• Actual acceleration time also depends on 2204

2203 DECELER TIME 1
Sets the deceleration time for maximum frequency to zero for ramp
pair 1.
• Actual deceleration time also depends on 2204
