20BD077A0AYNACC1

The Allen Bradley PowerFlex 700 model 20BD077A0AYNACC1 serves as a high-performance AC drive tailored for demanding applications. This drive operates efficiently at an input voltage rating of 650V DC, with a maximum current capacity of 84.5 Amps. For motor control applications, it can deliver up to 60 horsepower under normal operating conditions.

Designed with an adjustable PWM frequency at 4 kHz, this unit also supports carrier frequencies of 2, 4, 8, and 10 kHz, with the standard drive rating based on the 4 kHz setting. The frequency accuracy is maintained within ±0.01% of the specified output frequency, ensuring reliable performance. It features a standard encoder feedback setup, which provides vital position and speed information for precise control.

This drive is sensitive to environmental conditions; it can withstand vibration levels of 0.152 mm displacement and can handle shock levels of up to 15 G for brief durations. An AC input overvoltage trip mechanism activates at 570V AC when operating at 480V.

A typical digital input latency of 9.2 ms for stop signals is noted, important for swift control response in servo motor contexts. Additionally, a thermistor monitors the heat sink temperature, with the microprocessor managing an overtemperature trip to protect the system. Two programmable acceleration and deceleration times enhance operational flexibility. Each of these times can be set between 0 and 3600 seconds in increments of 0.1 seconds, adapting to a variety of application requirements.
