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.

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.
0 = NOT SEL – Disables selection, the first ramp pair is used.
1 = DI1 – Defines digital input DI1 as the control for ramp pair selection.
• Activating the digital input selects ramp pair 2 .
• De-activating the digital input selects ramp pair 1 .
2…6 = DI2…DI6 – Defines digital input DI2…DI6 as the control for ramp pair selection.
• See DI1 above .
7 = COMM – Defines serial communication as the control for ramp pair selection.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the control for ramp pair selection.
• De-activating the digital input selects ramp pair 2
• Activating the digital input selects ramp pair 1 .
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for ramp pair selection.
• See DI1(INV) above .
2202 ACCELER TIME 1
0 .0…1800 .0s
0 .1 s
30 .0 s
Sets the acceleration time for zero to maximum frequency for ramp pair 1. See A in figure.
• Actual acceleration time also depends on 2204 RAMP SHAPE .
• See 2008 MAXIMUM FREQUENCY,
2203 DECELER TIME 1
0 .0…1800 .0s
0 .1 s
30 .0 s
Sets the deceleration time for maximum frequency to zero for ramp pair 1 .
• Actual deceleration time also depends on 2204 RAMP SHAPE .
• See 2008 MAXIMUM FREQUENCY,
