できる。In the above configuration, during normal machining, the main shaft 2 is driven by the electric motor 1 at a high speed V0 set by the speed command device 10. The angle detector 8 always detects the rotation angle θ of the main shaft 2, and when this rotation angle θ matches the deceleration start angle θ, T, a signal is output from the comparator 18.
AND gate 19 opens, and a slow speed command is given to electric motor 1 in response to a stop command from stop command device 17 . Therefore, the electric motor 1 is decelerated. When the rotational speed of the electric motor 1 decreases to a very slow speed ■, the electric motor 1 continues to rotate while maintaining the slow speed ■. In this state, when the rotation angle θ of the main shaft 2 matches the stop auxiliary angle θ1, the AND gate 21 is opened by a signal from the comparator 20, and a zero speed command is given to the motor 1 by a stop command from the stop command device 17. , electric motor 1
is the target stopping angle θ due to inertia. Rotate until it stops. Depending on the motion speed V0 at high speed, the time required for deceleration varies, and the rotation angle until the slow speed ■1 is reached changes, but θ1-
θ5. =K・vo (K is a constant), deceleration start angle θ
, T should be assisted. Therefore, if the angle is set using the angle setting device 16 as shown in FIG. 2, the electric motor 1 will decelerate and stop according to the speed curve shown in FIG. 3, and the mold 3.5 will be stopped. Target angle θ. can be stopped.
このように停止に先立って電動機１の回転速度を微速Ｖ
、に減じると、誤差を少な（して精度よ（停止させるこ
とができる。In this way, prior to stopping, the rotational speed of the electric motor 1 is reduced to a very slow speed V.

できない。That is, when stopping the electric motor 1, high speed ■. If the stop command is issued as is, it will not be possible to stop the motor at the desired angle with high precision due to the influence of errors in the rotational speed of the electric motor 1, mechanical load fluctuations, and errors in signal transmission time in the electrical system.
しかし、微速■、に下げた後に零速度指令を与えれば、

うに６５丁を決める。Then, since the angle at which the electric motor 1 rotates from slow speed 1 to stop is constant within the error range, the stop assist angle θ1 at which the zero speed command is issued is uniquely determined. Also, the deceleration start angle θ, T is the steady rotation speed ■. and slow speed■1

行ない得る。After stopping, if a phase shift occurs between the molds 3.5, a phase matching operation is performed as follows. That is, the selector switch 12 is switched to the speed command device 11 side, a slow speed command is given to the electric motor 1, and the motor 1 is started and operated at slow speed (1). Here, the angle detector 8 detects the rotation angle θ of the main shaft 2 rotating at a slow speed, and the angle detector 9 detects the rotation angle θ of the driven shaft 4 in a stopped state.
1 is detected, and the subtracter 22 subtracts the two. Then, the angle difference between the rotation angle θ1 and the rotation angle θ (θ
, -〇A) is the target stop angle θ. If the difference between the angle and the stop auxiliary angle θ1 is equal to (θ.-θI), the AND gate 24 is opened by the signal from the comparator 23, and the stop command device 1
A zero speed command is given to the motor 1 by the stop command from the motor 7, and the motor 1 is stopped. Therefore, as a result, the mold 3 on the main shaft 2 side stops at the rotation angle θ, and the main shaft 2
Since the phases of the side molds 3 can be matched, even if the workpiece 6 is subsequently carried in and held between the molds 3.5, the uneven pattern of the workpiece 6 will not be crushed, and the work can be carried out efficiently. I can do it.
