DRIVE CONTROL APPARATUS
First Claim
1. A drive control apparatus comprising:
- a detection unit that detects at least one of a speed, a position, acceleration, an amount of movement, a movement direction and torque, and outputs one or more detected operating values (“
DOV”
) physical parameter that indicate movement of a drive unit; and
a cut off unit that cuts off supply of electric power to the drive unit when a DOV physical parameter is outside a first upper to lower limit range, and wherein a warning is output when the DOV physical parameter is within the first range and additionally is outside a second upper to lower limit range, based on an input signal from the detection unit,wherein the second range is narrower than the first range.

Abstract
The operation state of a servo motor is monitored and output to a user before automatic termination of power to the motor. A servo system includes a servo motor and a safety unit. The safety unit cuts off electric power to the servo motor when at least one of a speed, a position, acceleration, an amount of movement, a movement direction, and torque of the servo motor is outside a first operation range. Furthermore, the safety unit outputs a warning when at least one of the speed, the position, the acceleration, the amount of movement, the movement direction, the torque is within the first operation range, but is outside a second operation range that is narrower than the first operation range. User controls allow reduced operation when outside the second operation range.
