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 of these.
Code Description
2201 ACC/DEC 1/2 SEL
Defines control for selection of acceleration/deceleration ramps.
• Ramps are defined in pairs, with one ramp for acceleration and one
ramp for deceleration.
• See below for the ramp definition parameters.
0 =
– Disables selection, the first ramp pair is used.
NOT SEL
1 =
1 – Defines digital input

• Activating the digital input selects ramp pair 2.
• De-activating the digital input selects ramp pair 1.

2202 ACCELER TIME 1
Sets the acceleration time for zero to maximum frequency for ramp
pair 1. See A in the figure for parameter 2204.
• Actual acceleration time also depends on 2204
• See 2008
2203 DECELER TIME 1
Sets the deceleration time for maximum frequency to zero for ramp
pair 1.
• Actual deceleration time also depends on 2204
• See 2008
