If set the tension through this mode,the maximum tension 14-06 must be set. In general, the maximum value set by analog value and set in maximumpulse both correspond to the maximum tension. The pulse can be set by terminal DIH.• When 14-04=2, the tension is set by communication. If perform the control with upstream equipment, the tensioncan be set by communication. There are two ways to realize communication setting of tension: 1) Change value of14-05, then 14-04 shall be set to 0; 2) Set the tension through Modbuscommunication address H100C, 14-04 shallbe set to 2 and the Modbuscommunication address H100Cshall be set from 0 to 30000.• 14-07is the zero-speed tension increase. It is used to set the tension of the system when it is at zero-speed. It ismainly for overcoming static friction when startup or keep certain tension when the system is at zero-speed. If thecontrol tension is small and it is hard to start, it is allowed to properly increase the setting value of the parameter.• 14-08is the zero-speed threshold. When the running speed of the inverter is below the set speed of the parameter,it is considered that the inverter is under zero-speed operation status.• 14-09is the tension taper. The parameter is only used for wind-up control. For the wind-up control, sometimes, it isneeded to reduce the tension while increasing the curling radius to ensure a good curling of the material.Formula of tension taper: ( ) ( ){ }F=F0* 1 K* 1 D0+D1 / D+D1− −  Wherein, F is the actual tension, F0 is the setting tension, D0 is the diameter of winding shaft, D is the actual curl-ing radius, D1 is the taper compensation correction of 14-10 set tension, and K is the tension taper.• 14-10is the taper compensation correction of tension which can relay the reduction curvature of tension.
