PMA90/180 Servo Amplifier
The PMA 90/180 Servo Amplifier has the ability to control either brushed or brushless motors all in one. The 40kHz PWM frequency is double that of most conventional drives, and enables direct connection to PML motors without an external choke.
The compact design and small footprint also saves valuable space. The drives are easy to set up whehter used stand alone or with digital motion controllers.
Features include amplifier enable and direction enable inputs (for connection to limit switches), full motor/drive protection, and potentiometer operation as an on-board full range reference signal.
Input gain, loop gain, offset parameters, component carrier and mode switches are adjustable. Configurable peak and continuous current limits allow high acceleration without sacrificing protection against continuous overloads. Peak current time can be adjusted from 50ms to 3 sec.
