Method and apparatus for controlling motors of different types
First Claim
1. A motor control module, comprising:
- an output power stage configured for a particular motor type;
a motor control unit coupled to the output power stage, the motor control unit configured to monitor status information about the motor control module including status information about the output power stage; and
status registers coupled to the motor control unit, the status registers having a format independent of motor type, the motor control unit configured to update the status information in the status registers;
the status registers including a drive status register, the drive status register indicating the status information about the output power stage.

Abstract
In order to reduce the time and expense of designing and operating a motor control system with multiple motors of different types, a motor control system is provided with motor control modules that monitor and record status information and update settings in a uniform manner regardless of the motor type under control. Each motor control module includes an output power stage and a motor control unit connected to each other. The status information includes status information about the output power stage or a current control loop connected to the output power stage. The settings include conditions monitored by each motor control module and corresponding actions taken by each motor control module based on the conditions. A host processor connected to the multiple motor control modules may request the common status information and send messages to update common settings of the motor control modules.
