Motor driving system and motor controller

摘要

A motor controller (13) and a safety module (14) comprise a motor control circuit part (31) configured to perform the power supply control to a motor (2) in accordance with a predetermined driving control command, a function of selecting and executing either a control deceleration mode in which the deceleration and stopping of the motor (2) are achieved by inputting a higher control command that is in accordance with a predetermined higher control operation pattern inputted from a controller (11) to the motor control circuit part (31) as the driving control command, or an active deceleration mode in which deceleration and stopping of the motor (2) are achieved by inputting an internal deceleration command generated inside a motor controller (13) in accordance with a predetermined self-control operation pattern to the motor control circuit part (31) as the driving control command when a safety request signal is inputted, and a comparing and monitoring part (41) configured to monitor whether or not a driving state amount exceeds a predetermined operation monitoring pattern when a safety request signal is inputted.
