Abstract
A motor control system includes a motor, and motor control circuitry that controls driving electric power for the motor based on a driving state quantity of the motor, and upon input of a safety request signal from outside the motor control circuitry, monitors a relationship between a driving state quantity and an operation monitor pattern selected from multiple kinds of operation monitor patterns using multiple simultaneously functioning safety function software modules.
Claims20
A motor control system, comprising:
- a motor;
- and
- motor control circuitry configured to
- control driving electric power for the motor based on a received driving state quantity of the motor, and
- upon input of a plurality of safety request signals from outside the motor control circuitry, simultaneously monitor a relationship between the received driving state quantity and the respective operation monitor pattern, each operation monitor pattern selected from a plurality of kinds of operation monitor patterns stored in a memory based on the respective safety request signal of the plurality of safety request signals, using a plurality of simultaneously functioning safety function software modules.

A motor control apparatus, comprising:
- control circuitry that controls driving of electric power for a motor and is configured to,
- upon input of a plurality of safety request signals indicating whether to decelerate and/or stop the motor, simultaneously monitor a relationship between a received driving state quantity and the respective operation monitor pattern, each operation monitor pattern selected from a plurality of kinds of operation monitor patterns stored in a memory based on the respective safety request signal of the plurality of safety request signals, using a plurality of simultaneously functioning safety function software modules.
A method for controlling a motor, comprising:
- selecting, using motor control circuitry, an operation monitor pattern from a plurality of kinds of operation monitor patterns stored in a memory;
- and
- inputting, using the motor control circuitry, a monitor result obtained by a first safety function software module among a plurality of simultaneously functioning safety function software modules into a second safety function software module among the plurality of safety function software modules,
- wherein the motor is controlled using the motor control circuitry driving electric power for the motor that is configured to, upon input of a plurality of safety request signals indicating whether to decelerate and/or stop the motor, simultaneously monitor a relationship between a driving state quantity and the respective operation monitor pattern, each operation monitor pattern selected from a plurality of kinds of operation monitor patterns stored in a memory based on the respective safety request signal of the plurality of safety request signals, using the plurality of simultaneously functioning safety function software modules.
