Ratio
Ratio mode sets the section speed to the line speed multiplied by the ratio input. To select ratio mode, set SETPOINT
SUM 1:: RATIO 0 to 0.00 percent. Terminal A4, LINE SPEED REFERENCE, supplies the line speed signal. Termi-
nal A2, DRAW/RATIO, receives the ratio setpoint. It is multiplied by the line speed to produce the speed demand.
The maximum range of terminal A2 is -300 to +300 percent. To set a ratio range of 50 to 200 percent, set ANALOG
INPUTS:: ANIN 1 (A2):: CALIBRATION to 2.0000, MAX VALUE to +200.00%, and MIN VALUE to +50.00%.
Now 0 to 10 volts on input A2 produces a ratio of 50 to 200 percent. The overall speed demand is clamped to a maxi-
mum of 105 percent so ratios of more than 100 percent can only be used at less than full line speed.
Torque
Torque mode is armature current control. To achieve current control, an overspeed is added to the line speed demand.
Since the actual section speed is held at line speed by the web, the speed loop saturates causing the current demand to
equal the current limit. This function is similar to that discussed earlier in this chapter's CPW section.
24 VDC at terminal C4 selects torque mode. JOG/SLACK:: TAKE UP 1 sets the overspeed. It determines how much
faster than line speed the section runs if it is not held back by the web, for example if the web breaks. Current loop pa-
rameter BIPOLAR CLAMPS must be set to ENABLED and CUR. LIMIT/SCALER set to 200 percent.
The signal at terminal A5, TENSION SETPOINT, sets the initial tension demand. It is combined with the loss com-
pensations to produce the current limit. Follow the instructions in the CPW section, pages M-17 and M-18, for setting
up the loss compensation parameters. Terminal C6, REVERSE, is connected to TORQUE CALC.:: OVER WIND. 24
VDC at terminal C6 switches the current limits, permitting the section to run in reverse.
NOTE. Set PID:: ENABLE to OFF when running in torque mode.
