Allen - Bradley 1391-AA15 AC Servo Controller

The 1391-AA15 AC Servo Controller, made by Allen - Bradley, is a 3-phase 220V AC Single-Axis servo controller dedicated to closed - loop positioning systems. It utilizes a Pulse Width Modulation mechanism to control and modulate the position and rotary motion of various machine parts during automated machine processes.

This controller has a nominal BUS output voltage of 300V DC with an integrated shunt regulator. It has a continuous output current of 15A that peaks at 30A (RMS). The continuous output power is 5KW, peaking at 10KW, and it provides a maximum input circuit breaker rating of 17A (RMS). It also has an interrupt rating of 1300A (Symmetrical Amperes) and offers a Static Gain of 1.5 x RATED MOTOR/RPM (A/RPM).

The 1391-AA15 features protection against transient voltage and an integrated circuit breaker. It has a shunt regulator resistor that dissipates all heat generated by the motor during regenerative braking. Additionally, it offers a compact Logic box that can be easily inserted and removed for quick diagnostics and troubleshooting.

The 1391-AA15 controller from Allen-Bradley is a pulse width modulated type of servo controller. It is manufactured as a member of the Allen-Bradley AC Servo 1391 series of industrial servo controllers. The 1391-AA15 servo controller uses a single axis and it operates with AC voltage. This controller can support a rated RMS continuous current of 15 Amps and a rated RMS peak current of 30 Amps. It can be used to convert 3-phase AC input voltage with 50 to 60 Hertz.

The 1391-AA15 has a Form Factor of < 1.03 and an adjustable peak current ranging from 20 - 200% of the rated motor current (90A max). The controller has a total efficiency of 85% with a modulation frequency of 2.5 kHz (- + 10%). It has a maximum drift of 0.07RPM/0C.

This controller has zero dead bands, with an integral fan output of 50CFM. It has a 230V AC (3-phase) input voltage at 50-60Hz from the transformer, a control voltage of 35.5V AC, and a Transformer input tolerance of + 10% to - 15%. Its operating temperature ranges from 0 -60 0C (32 - 140 0F) at 5 - 95% relative humidity (non-condensing), and it can maintain optimal function at a maximum height of 1000m (3000ft). The 1391 - AA15 weighs approximately 9.97Kg (22lb) and is UL, CSA, and IEC - certified.
