The 1391-AA15 AC Servo Controller by Allen-Bradley is a 3-phase 220V AC Single-Axis dedicated servo controller with a Pulse Width Modulation mechanism used with a closed-loop positioning system to control and modulate the position and rotary motion of various machine parts in an automated machine process. The controller has a nominal BUS output voltage of 300V DC with an integrated shunt regulator and it has a continuous output current of 15A which peaks at 30A (RMS). It has a continuous output power of 5KW which can peak at 10KW and it provides a 17A (RMS) maximum input circuit breaker rating. It also has an interrupt rating of 1300A (Symmetrical Amperes) and it offers a 1.5 x RATED MOTOR/RPM, Static Gain (A/RPM). The 1391-AA15 features protection against transient voltage and an integrated circuit breaker, a shunt regulator resistor which dissipates all heat produced by a motor during regenerative braking, and it offers a compact Logic box, which can be easily inserted and removed, for quick diagnostics and troubleshooting.
The 1391-AA15 offers a Form Factor of <1.03 and it offers an adjustable peak current of 20-200% of the rated motor current (90A max). The controller has a total efficiency of 85% with 2.5 kHz (-+10%) modulation frequency and it has a maximum drift of 0.07RPM/0C. The 1391-AA15 has zero dead bands, with 50CFM integral fan output, and it has 230V AC (3-phase) input voltage at 50-60Hz from the transformer, with 35.5V AC control voltage and with a Transformer input tolerance of +10% to -15%. Its operating temperature ranges from 0-60 0C (32-140 0F) at 5-95%, non-condensing relative humidity, and it can maintain optimal function at a maximum height of 1000m (3000ft). The 1391-AA15 weighs about 9.97Kg (22lb), and it is UL, CSA, and IEC-certified.
