Chapter 6 – Parameters6-20ACH 500 Programming ManualGroup 20.3Accel/DecelThese parameter values can be altered with the ACH 500 running, exceptthose marked with (O). The Range/Unit column in Table 6-12 showsparameter values. The text following the table explains parameter values indetail.Table 6-12 Group 20.31 ACC/DEC 1OR2 SEL This parameter defines which Digital Input (1 – 6) is used to select theAcceleration/Deceleration Ramp used. 0 V DC equals Acc/Dec Time 1, 24 VDC equals Acc/Dec Time 2.2 ACC/DECRAMP SHAPEThis parameter allows you to select the shape of the acceleration/decelerationramp. The available options are:LINEARSuitable for drives requiring steady acceleration/deceleration and/or slowramps.S1 SHAPESuitable for ramp times less than one second.S2 SHAPESuitable for ramp times less than 1.5 seconds.S3 SHAPESuitable for ramp times up to 15 seconds.Figure 6-5 shows acceleration and deceleration ramp shapes.Parameter Range/Unit Description1 ACC/DEC 1OR2 SEL (O) Not Sel/DI1–DI6Acceleration/Deceleration rampselection.2 ACC/DEC RAMP SHAPE Linear/S1 – S3 Accel./Decel. ramp shape selection.3 ACCEL TIME 1 0.1 – 1800s Time for output frequency min. tomax. acceleration ramp 1.4 DECEL TIME 1 0.1 – 1800s Time for output frequency max. tomin. deceleration ramp 1.5 ACCEL TIME 2 0.1 – 1800s Time for output frequency min. tomax. acceleration ramp 2.6 DECEL TIME 2 0.1 – 1800s Time for output frequency max. tomin. deceleration ramp 2.7 ACCEL REF2 TIME 0.1 – 1800s Ref2 acceleration ramp time for0 – 100%.8 DECEL REF2 TIME 0.1 – 1800s Ref2 deceleration ramp time for100 – 0%.
