ばならないという問題がある。Conventional technology The control motor of the NC (numerical control) device is removed from the NC device for maintenance etc.
When attaching this to the NC device again, it is necessary to align the origins of the NC device and the control motor with each other. That is, the NC device generally determines that the return to origin is complete when an activation signal is generated from the near-origin limit switch LSA for attenuating the movement speed, the origin limit switch LSB indicating the mechanical origin, and the origin signal for the control motor. If the origin positions of the NC device and the control motor are misaligned, these signals will not be generated at the same time, making it impossible to complete the return to origin, and as a result, the NC device will not be able to operate. . For this reason, conventionally, each time a control motor was installed, the angle at which the motor was installed and the positions of the limit switches LSA and LSB were changed, and position adjustments and test runs were repeated until the return to origin was completed. As a result, a great deal of effort and time was required for adjustment. In addition, limit switches LSA and LSB
If the position is changed, the origin position of the NC device will change, so there is a problem in that all NC data must be changed.

A case will be explained in which the device is removed from the main body and reattached after maintenance. motor 10
Before removing the NC device 12 from the NC device 12,
Return to the origin position. As described above, this is done by detecting the operating signals of the limit switches LSA and LSB and the origin signal of the motor 10.
Next, when the motor 10 is removed and installed after maintenance, the motor 10 is first connected to the origin check device 14 as shown in FIG. This allows the origin check device 14 to move the motor 10
5V power is supplied to motor 1 in this state.
By manually rotating the rotating shaft 10a of 0, a pulsed A-phase signal, a B-phase signal, as shown in FIG.
An origin signal is generated by a pulse generator within the motor 10 and sent to an origin check device 14.
