Features: • BL7080x can be used with any motion controller, PLC indexer or other controller that generates pulse and direction commands, or can be set to perform preset moves or jog functions. • Requires 24-80 VDC power supply. • Continuous current of 7A, peak current to 14A • Speeds to 6000 rpm. Motor and load dependent. • 20 kHz precision PWM amplifier. • Compatible motors and extension cables available from stock. • Compact size (2 x 3 x 6 inches). • Screw terminal connectors for power, motor phases and I/O. • Pluggable, industry standard D connector for encoder and commutation signals. Options • Eight Applied Motion Alpha series servo motors specifically designed for optimized performance with the BL7080X amplifier. These motors feature low profile right angle strain relief, shielded motor and encoder cables and mil style connectors. • Standard or custom length extension cables for the motor and encoder that allow for quick, plug and play system set up. • Regeneration clamp circuit (recommended). • Recommended power supplies: PS430, PS1050 and PS1070. |
Description: The BL7080x servo amplifier is suitable for a wide range of motion applications and is designed around a precise, powerful and efficient PWM amplifier. BL7080x is a servo amplifier that can accept pulse and direction commands from any type of motion controller as well as providing the user with preset programming capabilities. Tuning the PID loop on the BL7080x is easy with our Quick Tuner&153; software, featuring a built-in oscilloscope. Software selection of encoder line count and commutation sequence allows the motor to be configured without swapping wires.
