PROBLEM TO BE SOLVED: To make an accurate comparison between motor load and threshold even if voltage applied to a motor changes. SOLUTION: The voltage applied to a motor (motor voltage) (b) changing with power supply inputted (on) in another actuator is detected. The variation ΔS" in the cycle of a pulse signal corresponding to the variation in detected voltage is subtracted from the variation in the cycle of the detected pulse signal. A comparison is made between the subtracted variation of the pulse signal and threshold to stop the motor drive or reverse it by a fixed stop amount. |
