Therefore, the primary side of the transformer 58 is moved.

The secondary output of the transformer 58 is rectified by a rectifier 60 and supplied to the I2 electromagnetic brake.

The overall Kib operation of such a brake control device is as follows.

Now, it is assumed that the tension is controlled to a predetermined tension setting value. At this point, due to some reason (disturbance), the pestle!
When the output speed changes, this change is detected by the tacho generator 80 and added to the differential circuit 32. At this time, a differential circuit? It is not uncommon for capacitors to be switched depending on the wire drawing speed, etc.

This differential signal is applied to the adder 42 via the PID 41'49ηjli 40, so that a current proportional to the change in delivery speed flows through the electromagnetic brake 9, changing the braking action. That is, when the feeding speed changes, a correction action is performed in accordance with the change, so that the speed change can be suppressed to a minimum. It should be noted that controlling the Le'Hr3 release speed in this way causes a change in tension, but does not cause any problems in practical use.

When the track rolling stock is operated using the control system (substantially the same as the conventional system), the line speed changes greatly as shown in Figure 11101'.
