4.5.7 DanStpt_Pct
This is the Dancer Set point in percent.
Usage - Connect to the Dancer Set Point value tag or set the constant value in the
JSR. (Typical usage is setting to a constant, approximately 50%)
4.5.8 RfRate_PctSec
This is the rate limit of the reference set point. The reference set point in percent is
incremented or decremented by this value. For example, if RfRate_PctSec were set
to 1, than it would take 100 seconds for the reference to ramp from zero to 100
percent. If RfRate_PctSec were 100, then it would take one second for the reference
to ramp from zero to 100 percent. This is used for “bump less” transfers in and out of
tension control.
Usage - Connect to the Reference Rate value tag or set the constant value in the
JSR
4.5.9 TenDanFb_DC
This is the Tension or Dancer Feedback in data counts. In the Application Module,
this signal is set up to come directly from an analog input 2 of the PowerFlex 700S.
Usage – Connect to the tag that is the tension or dancer feedback of the drive
section
4.5.10 .TenDanFbMin_DC
This is the value of TenDanFb_DC that equates to 0 percent.
Usage - Connect to the Tension or Dancer Feedback Minimum value tag or set the
constant value in the JSR.
4.5.11 TenDanFbMax_DC
This is the value of TenDanFb_DC that equates to 100 percent.
Usage - Connect to the Tension or dancer feedback maximum value tag or set the
constant value in the JSR.
4.5.12 TrqFb_PU
This is the torque feedback for “Closed Loop” torque control when trimming speed.
Usage – Connect to the tag that is the actual torque feedback (PU) of the drive
section.
4.5.13 TrimKp
This is the proportional gain of the trim PI regulator. This affects both the calculated
value of the integral and proportional control algorithm.
Usage - Connect to the Trim Kp value tag or set the constant value in the JSR
4.5.14 TrimWld
This is the lead frequency of the PI regulator in radians/second. This affects the
calculated value of the integral control algorithm.
Usage - Connect to the Trim Wld value tag or set the constant value in the JSR
4.5.15 TrimLimSpd_Pct
This is the maximum amount of speed trim the regulator will output. This value is in
percent of Maximum Line Speed.
Usage - This value is typically set to 10%. Connect to the Trim Limit value tag or set
the constant value in the JSR.
