PARAMETER DESCRIPTION 307
5.15.8 Constant linear speed mode

Constant linear speed mode(14-00(P.600)=”4”)，used to select the method of acquiring the target constant linear
speed..


When 14-44(P.656)=0, linear speed is set by parameter 14-45(P.657).

The linear speed is obtained by analog value or pulse input（14-44(P.656)=“1”）
The maximum linear speed 14-30(P.628) must be set correctly. The maximum analog value and pulse input
corresponds to the maximum linear speed.

Obtain linear speed through communication（14-44(P.656)=“2）
Set address H100B through modbus. The setting range is 0~6500.0m/min
5.15.9 Tension closed-loop limiter

Closed-loop speed control mode（14-00(P.600)=“2”），used to select the PID regulator output limit benchmark and
limit bias.


Under closed-loop speed control mode, PID regulator limiter bias is set by 14-47(P.659). If this parameter is set to
0,when the system is at zero speed, the controller will not work. Appropriately setting bias can avoid this problem.
