| Introduction to PMM80 | |
PMM series integrated low-voltage servo motor is a new servo product independently developed by Limax. Based on the leading MBD development method and integrated development concept, it integrates permanent magnet synchronous motor, encoder and servo driver, adopts FOC field oriented control technology and SVPWM.(Space Vector Modulation) technology, support EtherCAT/CANopen bus control, with small size and simple wiring, widely used Scenes such as AGV, mobile robots, and collaborative robots.

| feature of product | |
·Highly integrated design reduces installation complexity and saves space · Eliminate the matching process between the driver and the motor, reducing the cost of use
· Adopt EtherCAT/CANopen protocol (DS402)Wide voltage input （16~80VDC), can be powered by battery
·Optional off brake protection
· Integrated single-turn absolute encoder, limited zero memory
· Provide speed and position feedforward parameter configuration to improve response speed
·Integrated I/O, can be set to positive limit, negative limit, origin, multi-function digital output, pulse input detection
Real-time fault monitoring and protection functions, including overcurrent, I2T overload, overvoltage, undervoltage, overheating, overspeed, and out of tolerance protection
· Provide application scenarios and development kit support for multiple scenarios, shortening user development cycle
· Can be customized in a variety of sports mode features: two-wheel differential drive mode, wheelset slip alarm, etc.
