current line speed and the inverter output frequency. The equation is as follows:
D (i V) / (π n)=××
Wherein D is the curling radius, I is the mechanical transmission ratio, V is the line speed, n
is the motor speed.
When the system operation speed is slow, the line speed of material and the output
frequency of the inverter will be low. Then a little detection error will cause a big error in the
curling radius calculation, so that a lowest line speed P.629 must be set. When the line
speed of material is lower than P.629, the curling radius is stopped to calculate and the
current value of curling radius remains unchanged. The value should be set below the
normal working line speed.
• P.610=1, the calculation of thickness accumulation: the curling radius is worked out through
the encoder on the motor side and the gear feedback. In this condition, connect the pulse
signal to A1/B1 on PG03 and set the encoder input mode setup (P.351), the mechanical
transmission ratio (P.603), the number of pulses per revolution of the encoder (P.350), the
number of turns each layer (P.620) and the material thickness 0 (P.622).
• P.610=2, the calculation through thickness accumulation: the curling radius is worked out
through the encoder on the winding shaft. In this condition, connect the pulse signal to
the terminal HDI of the inverter and calculate the curling radius through the number of
pulses each turn (P.619), the number of turns each layer (P.620) and the material
thickness 0 (P.622).
• P.610=3, when testing the curling radius with curling radius test sensor, the input channel of
curling radius sensor can be the analog value or the pulse input.
• P.611 is used to set the maximum curling radius. When P.610=3, the parameter must be set
and the maximum of the analog value or pulse signal corresponds to the set value of the
parameter P.611.
• P.612 is used to set the winding shaft diameter. The curling radius calculated by the curling
radius calculation module of the inverter is limited by P.611 and P.612.
• P.613 is used to select the input channel of initial curling radius.
1) When P.613=0, the initial curling radius is set by the parameter P.614~P.616. The initial
value of curling radius can be determined through two multi-function terminals, the
selection of initial curling radius is as follows:
The external terminal 1
The external terminal 2
The initial curling radius source

2) When P.613=1, the initial curling radius is determined by the analog value. When the
initial curling radius does not count from the hollow curling radius, the initial curling
radius can be selected by the external terminal. For wind-up control, the system
default initial curling radius is the diameter of winding shaft (P.612). For roll-down
control, the system default initial curling radius is the maximum curling radius
