Linear speed input
For winding radius source, if linear speed calculation or tension control mode is selected as closed-loop speed
control, accurate linear speed signal is required. The convenient way to obtain linear speed is through analog
output of operation frequency of traction (constant speed) inverter. The operation frequency of traction inverter
corresponds to the linear speed linearly, needing only to set the maximum linear speed (14-30(P.628)) to the
corresponding linear speed of the maximum frequency of the operation frequency of the traction inverter.
14-29(P.627) is used for selecting the method or channel for obtaining linear speed.
1.
When 14-29(P.627)=0,there is no linear speed input.
2.
When 14-29(P.627)=1,linear speed is obtained through analog value or pulse input. The correct maximum
speed14-30(P.628), analog value or pulse input`s setting corresponding to maximum linear speed is required.
3.
When the linear speed (14-29(P.627)=2) is obtained through communication method, it is set by the modbus
communication address H100A and the setting range is 0.1~6500.0m/min.
14-31(P.629) is for setting the minimum speed of winding radius when the calculation starts. When the inverter
detects that the linear speed is lower than the value, winding radius calculation ceases. By correctly setting this
value, deviation of winding radius calculation when speed is reducing can be effectively avoided. This value should
be set over 20% of the maximum linear speed in general.
14-32(P.630) is for displaying the actual linear speed in real time.
