PWM amplifier DC servo driver PMA□□-24VA series/PMA□□-48VA series
Servo Techno Co., Ltd.
About This Product
■Summary
The PMA□□VA series is a DC servo driver that achieves low cost while pursuing servo performance. The power supply was developed as a single power supply for DC24V or DC48V battery power.
The control loop is dedicated to torque (current) control, but voltage control can be added as an option. A compact design has been achieved by eliminating the electrolytic capacitor in the main circuit and using a ceramic capacitor. For commands, input ±10V analog commands from the external controller. The main circuit is a single-phase bridge configuration.
Features
■High performance
・Current resolution 0.1% or less
・Current response 200μs or less (resistive load)
■Multi-function
・Standard: Torque (current) control
・Option: V (voltage control)
■Lightweight, compact, low cost
・A more compact design has been achieved by eliminating the electrolytic capacitor in the main circuit and replacing it with a ceramic capacitor.
・It has been made lighter and smaller by attaching a surface-mounted power FET directly to the board and dissipating heat directly to the case.
■Single power supply
The DC24V version has a wide input range of +9V to +36V, and the DC48V version has a wide input range of +18V to +63V, making it ideal for battery power.
■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
・Photocoupler isolation of input signal
■Applications
Various robots, AGVs, power amplifiers, variable power supplies, VCMs, and others.
