Digit 3: Step Settings
This digit defines what accel/decel profile the speed command will follow and the direction of the
command for the current step. In addition, if a relay or opto output (parameters A055, A058 and A061)
is set to 15 “StpLogic Out”, this parameter can control the status of that output.
Any StepLogic parameter can be programmed to control a relay or opto output, but you can not
control different outputs based on the condition of different StepLogic commands.
StepLogic Settings
The logic for each function is determined by the four digits for each StepLogic parameter. The
following is a listing of the available settings for each digit.
Refer to Appendix
E for details.
