RUN RAMPS P 1/1
The Run Ramps parameters determine the acceleration and deceleration rates that are used during RUN.
The Ref Ramps (CP-300) is the reference speed in EU/Tm used to define the RUN ramps. Acl Tm RUN
(CP-301) is the time it would take to accelerate from “0” to the Ref Ramps (CP-300) speed. The Acl Rt
RUN (CP-302) is the acceleration rate in EU/Tm/Sec. Dcl Tm RUN (CP-303) is the time it would take to
decelerate from the reference speed to “0” speed. The Dcl Rt RUN (CP-304) is the deceleration rate in EU/
Tm/Sec. Note that there are separate parameters that define the deceleration rates that are used for “H-
Stop” and "R-Stop.
Ref Ramps
The acceleration rate for the application selected are determined by the Acl Tm RUN (CP-301) and the Ref Ramps (CP-
300). The deceleration rate (from a faster speed to a slower speed) for the application selected, are determined by the
Dcl Tm RUN (CP-303) and the Ref Ramps (CP-300).
Acl Tm RUN
Acceleration Time RUN (CP-301) is the time that it takes to accelerate from 0 to the Ref Ramps (CP-300). Time is
consistant with Ref Ramps (CP-300) and Acl Rt RUN (CP-302).
Acl Rt RUN
Acceleration Rate RUN (CP-302) is the acceleration rate that the speed changes from 0 to the Ref Ramps (CP-300).
Rate is consistant with Ref Ramps (CP-300) and Acl Tm RUN (CP-301).
Dcl Tm RUN
Deceleration Time RUN (CP-303) is the time that it takes to decelerate from Ref Ramps (CP-300) speed to 0. Time is
consistant with Ref Ramps (CP-300) and Dcl Rt RUN (CP-304).
Dcl Rt RUN
Deceleration Rate RUN (CP-304) is the deceleration rate that the speed changes from Ref Ramps (CP-300) speed to 0,
while operating in App Select (CP-202) 1, 2, 4 or 5. Rate is consistant with Ref Ramps (CP-300) and Dcl Tm RUN (CP-
303).
Ramp Thd
When the difference between the ScaledRef (MP-30) and the RampedRef (MP-31) is greater than Ramp Thd (CP-305),
the ramp will work normally. When the difference between the ScaledRef (MP-30) and the RampedRef (MP-31) is less
than or equal to Ramp Thd (CP-305), the ramp will be bypassed. This avoids ramp delays for small speed changes but
still allows a ramp for large speed or for large Master SP (CP-210) changes.
