PROBLEM TO BE SOLVED: To provide a drive control system capable of detecting stepping out of a motor and drive its load accurately. SOLUTION: A drive control system detects actual rotating speed of a motor 4 controlled by a stepping motor/driver 3, to which prescribed command pulses have been given and compares a detecting speed obtained by the detection to a command speed output from a control section 2. Then when the detecting speed is not in the range of (command speed)-(the allowable speed of step out detection and the command speed)+(the allowable speed of step out detection), the motor is deemed to be in a stepped out state. |
