About This Product

■Summary

The PMA series is a DC servo driver that achieves low cost while pursuing servo performance. The power supply can be either AC or DC with a single power supply. The power supply voltage range is AC16V to 110V or DC20V to 150V. PMAxx-24V is for 24V batteries only. For the control loop, speed, torque (current), *voltage, and *position can be selected. (*Option) PMAxx-24V is current control only. Features

■High performance

・Speed ​​resolution 5,000:1 ・Current response 200μs or less (resistive load)

■Multi-function

・Standard: Speed ​​control, torque (current) control ・Options: Voltage control, position control, FV (encoder feedback), PLL control

■Lightweight, compact, low cost

By using surface-mounted components directly on the board without using HIC, which is disadvantageous in terms of cost, we have achieved cost reductions, and by integrating the heat dissipation fins with the case, we have made it lighter and smaller.

■Single power supply

・The power input range is wide, 16V to 110V AC or 20V to 150V DC, allowing you to input the optimal power according to the motor rated voltage. - Can also be powered by battery.

■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 ・Output current monitor

■Applications

Various robots, XY tables, measuring instruments, power amplifiers, variable power supplies, VCMs, AGVs, and others.
