For detailed information on applying Step Logic and Position StepLogic refer to Appendix E and
Appendix F .
Parameters A140-A147 are only active if P038 [Speed Reference] is set to 6 “Stp Logic” or 9
“Positioning”.
These parameters can be used to create a custom profile of frequency commands. Each “step” can
be based on time, status of a Logic input or a combination of time and the status of a Logic input.
Digits 0-3 for each [Stp Logic x] parameter must be programmed according to the desired profile.
A Logic input is established by setting a digital input, parameters
A051 - A054 [Digital Inx Sel], to 23
“Logic In1” and/or 24 “Logic In2” or by using Bits 6 and 7 of E248 [Enh Control Word].
A time interval between steps can be programmed using parameters A150 - A157 [Stp Logic Time x].
See the table below for related parameters.
The speed for any step is programmed using parameters
A070 - A077 [Preset Freq x].
The position for any step is programmed using parameters E230 - E245 [Step Units x].
Stop drive before changing this parameter.
