CP-311 Dcl Rt RStp
Deceleration Rate R-Stop (CP-311) is the deceleration rate that is used for R-Stop.
Minimum Value: 0 Maximum Value: 9999999
Default Value: 10.00 Units: Web EU/Tm/Sec
CP-312 Dcl Tm HStp
Deceleration Time H-Stop (CP-312) is the time, in seconds, that it takes to decelerate from the Ref Ramps (CP-300) speed
to 0, during H-Stop.
Minimum Value: 0.5 Maximum Value: 3600
Default Value: 10.00 Units: Seconds
CP-313 Dcl Rt HStp
Deceleration Rate H-Stop (CP-313) is the deceleration rate that is used for H-Stop.
Minimum Value: 0 Maximum Value: 9999999
Default Value: 10.00 Units: Web EU/Tm/Sec
CP-320 Kp VL
Kp Velocity Loop (CP-320) is the proportional gain constant for the PID velocity loop. An increase in Kp VL (CP-320)
creates a quicker response and a smaller error. However, a value that is too large will cause instability. If the integral
term is used, (i.e., Ki VL not equal to zero) then a nonzero Kp VL can actually improve the loop response and decrease
the overshoot to some extent.
Minimum Value: 0 Maximum Value: 200
Default Value: 100 Units: Constant
CP-321 Ki VL
Ki Velocity Loop (CP-321) is the integral constant for the PID loop. Integral action provides for zero steady state error.
Increase Ki VL (CP-321) for a faster convergence to zero error. However, a value that is too large will cause instability.
Minimum Value: 0 Maximum Value: 200
Default Value: 60 Units: Constant
CP-322 Kd VL
Kd Velocity Loop (CP-322) is the derivative constant for the PID loop. Derivative action attempts to damp out
overshoot. Its effect is highly dependent on Kp VL and Ki VL, but, generally, too large a value causes instability.
Minimum Value: 0 Maximum Value: 200
Default Value: 120 Units: Constant
