About This Product

■Summary

PMA□□WA is a 2-axis DC servo driver that pursues servo performance while achieving a low price. The power supply is for single power supply specification DC12V/24V/48V battery power. The power supply voltage range is PMA□24WA (DC9V to 36V) and PMA□48WA (DC18 to 63V). The control loop is dedicated to torque (current) control. Features

■High performance

Current response 200μs or less (resistive load)

■Lightweight, compact, low cost

・By using CPLD, we were able to reduce the number of parts. - Eliminated the electrolytic capacitor for the main power supply and adopted a ceramic capacitor. - Lighter and more compact by integrating the heat dissipation fins with the case. ・In addition, the 2-axis integrated design is lighter, more compact, and lower cost than conventional products.

■Single power supply

It has a wide power input range of 9V to 36V DC or 18V to 63V DC, and can support battery power (DC power supply) from 12V DC to 48V DC.

■Isolated current sensor

Since it uses a small, high-performance current sensor using a Hall element, stable current control is possible without the influence of noise.

■Others

・Built-in dynamic brake ・Overvoltage (regeneration) protection ・Overheat protection ・Output short circuit protection ・Low voltage detection malfunction prevention

■Applications

AGV, various robots, XY tables, etc.
