4. Calculations:

4.1 Winding Ratio

H222 = Diameter(Core) / Diameter(Full Roll)

4.2 Setting the Normalization Factor for Speed Reference

P353 = (Max Velocity[meters/min] * Gear Ratio)Diameter(Core)[meters] * 3.141593

4.3 Find max winding torque referenced to the Motor Shaft

Twinding[Nm] = Max Tension[N] * Diameter(Full Roll) [m] 2 * Gear Ratio

4.4 Find Motor Rated Torque

Trated[Nm] = 9549 * Power(rated)[kW] Speed(rated)[RPM]

The first start sequence

5.8 Jog and Verify Motor Speed. Verify H143 jog reference speed. Default is 5% speed, on this case

0.58 Hz, 17.65 RPM. Force a jog command by setting H038 = 2001 In a typical application, this would be an appropriate point to Hand Tach

the motor.

5.9 If a problem with speed values occur use the following parameters to help troubleshoot. d310, d412, d344, d303 and P353.

5.10 Compensation of Friction Torque. Refer to instruction manual 6DD1-903-0AB0 Section 7.2.2 for specific procedure. In the case of the Demo Unit, this compensation is not required.

5.11 Turn on Binary Input #1, (ON/OFF) and then turn on Binary Input #4 (System Start). The motor will ramp up in speed very slowly to the setpoint of Analog Input #1. If Binary Input #1 is turned off, the drive will continue to operate, since the drive is looking for the main line speed to go to zero before stopping.

5.12 Set H154=0, this will activate the ramp function generator on the T400 card, and now Binary Input #1 will stop the drive.

5.13 Default ramp times are set for 30 seconds. Parameters H133 and H134 adjust the ramp rates.

5.14 Adjust Pot#2 on the Drive Demo Unit until the Tension Setpoint is positive(d304). It is also possible to use H560 and H561 as test points to inspect this value. Further adjust Pot#2 until the Tension setpoint is 0.1. When the drive is started the motor will rotate backwards at the saturation speed set by H145. The drive is attempting to develop tension, but since no tension exists the motor rotates backwards until the speed limit is reached (H145).

5.15 Speed deviation faults (F15) may occur. To avoid this set P792 = 200%.5.16 Apply manual pressure to the shaft of the motor and gently increase the

tension setpoint (Pot#2). Note that the Tension is ramped up through parameters H175 and H176. Default settings are 10 seconds.

5.17 Activate Binary Input #3 to change the winding direction. Originally, the motor was winding from Above, and now it has been selected to wind from Below. This will effectively change the motor rotation to the opposite direction.

5.18 To stop the motor, switch off the Tension Controller (Binary Input #2) and then switch Off the drive through Binary Input #1. Wait until the motor ramps to zero speed and then turn off System Start (Binary Input #4).

Other Features:

5.19 Standstill tension is set by H1895.20 Gearbox Ratio is set by H127, H42, 5.21 Winding Hardness Control H180, H181, H182, H183, H184, H185, H1865.22 Length Measurement and Length Stop is set through H218, H213, H252,

H541. Suggest setting H541=1000 for length measurement in Kilometers. 5.23 Web Break Detection is enabled by H285.
