PMD Juno MC71113 MC73113 MC78113 Outer-Loop Control ICs
Performance Motion Devices Juno is a family of motor-control integrated circuits with distinct velocity, torque and step-motor members. This review focuses on choosing the correct control function, motor support and package for a custom controller board.
Review Summary
Juno is useful for OEMs designing their own motor-control electronics with a clearly defined loop and motor requirement. Select the complete IC reference and external power stage; a Juno control chip is not a finished amplified drive, and family interface lists do not apply uniformly to every member. The same MC71113, MC73113 and MC78113 devices also support an outer-loop application: an external process sensor supplies pressure, temperature or another measured quantity through the specified analog or digital SPI path. PMD describes a PID outer loop that commands the downstream PI velocity loop. This is an additional control use of the identified IC family, not a separate motor amplifier or a different chip with an interchangeable model number.
