Line speed input
• If the curling radius source selects line speed calculation or tension control mode as the close-loop speed control,
it is required to obtain correct line speed signal. In general, the convenient way for obtaining line speed is through
analog output of operation frequency of traction (constant speed) inverter. The operation frequency of traction invert-
er corresponds with the line speed in linear. It only needs to set the maximum line speed (14-30) to the correspond-
ing line speed of maximum frequency of operation frequency of traction (constant speed) inverter.
• 14-29is used to select the way or channel for obtaining line speed.
1. When 14-29=0, no line speed is input.
2. When the line speed is obtained through the analog value or pulse input (14-29=1), the maximum line speed
14-30 must be correctly set. The maximum value of analog or pulse input corresponds with the maximum line
speed.
3. When the line speed is obtained through the communication method (14-29=2), it is set by the
Modbuscommunication address H100A and the setting range is 0.1~6500.0m/min.
• 14-31is used to set the minimum speed for starting calculation of curling radius. When the inverter detects that the
line speed is lower than the value, inverter will stop curling radius calculation. Correct setting of the value will effec-
tively avoid great deviation of curling radius calculation when the speed is reduced. In general, the value shall be set
to over 20% of maximum line speed.
• 14-32is used to display the actual line speed in real time. The current actual line speed can be known by the param-
eter.
