•
P.601 is used to select the curling mode which can be combined with the switching terminal
of wind-up and roll-down. If the switching terminal of wind-up and roll-down is inactive, the
set of actual curling mode is the same with the function mode. If it is valid, the set of the
actual curling mode is the same with the switching terminal of wind-up and roll-down.
•
P.602 is used to select whether support active take-up of material through inverse running
of motor. If “not allowed” is selected, during the roll-down control, the inverter can only
output torque when material is running forward.
During the roll-down, the frequency for
inverse take-up can be limited by setting the upper limit frequency.
•
P.603 is the mechanical transmission ratio. Mechanical transmission ratio=motor rotation
speed/winding shaft rotation speed, the mechanical transmission ratio must be correctly set
during the tension control.

The parameters in this part are only applicable in open–loop torque mode.

When P.604=0, the tension is set by the parameter P.605.
• When P.604=1, the tension is set by the analog value or pulse input terminal. If set the
tension through this mode, the maximum tension P.606 must be set. In general, the
maximum value set by analog value and set in maximum pulse both correspond to the
maximum tension. The pulse can be set by terminal HDI.
• When P.604=2, the tension is set by communication. If perform the control with upstream
