6B: APPLICATION EXAMPLE -
CONSTANT TENSION WINDER
SPECIFICATION:
Material is to be wound onto a reel at constant tension.
Tension is to be adjustable but independent of the rate of material
production and radius of the roll.
Tension control set point 1kohm pot
Maximum roll speed 1200 rpm
Minimum roll speed 300 rpm
Torque range 150Nm - 700Nm
Stop/start control 3 wire
Motor 132kW, 245A, 380V
Special requirements Stalled/jammed product
indication, loss of product/
loss of tension indication.
Operate the drive under torque limit with the torque limit adjusted
proportionally with the radius of the roll to provide constant
tension.
Use the frequency sense relay to indicate that the rotation is too
low (i.e., product stalled).
Use the AT FREQUENCY relay to indicate that the drive is
operating at the limit frequency (loss of product continuity).
ADJUSTMENTS :
Adjustment 10 MTR CUR
Set-up 245A
Notes -
Adjustment 11 MTR VOLT
Set-up 380V
Notes -
Adjustment 14 BOOST
Set-up 2.0%
Notes Needs to be set to give accurate torque at low
speed.
Adjustment 20 ILT SLIP
Set-up 1%
Notes This screen controls the current limit stability. If
set too high or to OFF the controller may surge.
Adjustment 25 MIN FLUX
Set-up 100%
Notes Full flux is needed for accurate linear control.
Adjustment 29 FR ON
Set-up 10Hz (300 rpm)
Notes Sense frequency for stall detection.
Adjustment 30 FR OFF
Set-up 9.0Hz
Notes Sense frequency for stall detection.
Adjustment 64 REF FR SEL
Set-up KEYBD
Notes The frequency setpoint is set by the keyboard
and is there to limit the speed if the tension is
released.
Adjustment 66 I/P MODE
Set-up Input Mode 1
Notes 3 wire start/stop with reset.
Adjustment 67 O/P RELAY 1
Set-up 0 = Fail-safe Fault
Notes Drive fault indicator.
Adjustment 68 O/P RELAY 2
Set-up 6 = Frequency Sense
Notes Stall indicator.
Adjustment 69 O/P RELAY 3
Set-up 10 = At Set Frequency
Notes No load indicator.
Adjustment 75 I LIM MODE
Set-up TQ
Notes Current limit on real current for linear torque
control.
Adjustment 76 I LIM SRC
Set-up 010V
Notes Use the 010V signal for torque reference.
Adjustment 77 AUTOBOOST
Set-up YES
Notes Use autoboost to maintain constant motor flux
at low speeds. This ensures accurate torque
limit control.
