PARAMETER DESCRIPTION 268
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..
Line speed setting
source
Parameter 14-45(P.657)setting
Obtain linear speed via analog value or pulse input
Obtain linear speed via communication
Linear speed setting value
Linear speed setting source
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.
Tension closed-loop
limit standard
Motor frequency as limit standard
Actual system linear speed as limit standard
Tension closed-loop limit
bias
Control limit bias by tension closed-loop
Under closed-loop speed control mode, PID regulator limiter bias is set by 14-17(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.
