PURPOSE:To automatically correct the mechanical loss data by calculating the compensation data of the mechanical loss and comparing it with the preset mechanical loss data to determine the correction coefficient at the time of pre-drive. CONSTITUTION:When an A-axis motor 22 is winding and a B-axis motor 2 starts the pre-drive, a switch 5 is set to the speed control mode contact 7 side, and the speed is synchronized with the line speed. After synchronization is completed, a speed feedback signal 11 and torque commands N, T are read. Next, the compensation torque TMC for the mechanical loss at the speed N is determined based on the mechanical loss data in a tension controller 8, the correction coefficient K=T/TMC is calculated, the mechanical loss data are multiplied by K and written in the mechanical compensation data. When the B-axis is operated for winding after the rewinding action, the switch 5 is set to the contact 6 side, and mechanical loss compensation is performed via the data at the time of pre-drive. Accordingly, winding can be performed invariably with the fixed tension. |
