Product Description:
The PQM1B600HT46S00 is a servo amplifier produced by Sanyo Denki for the PQ Type M Servo Amplifiers series. It converts a regulated DC bus into controlled three-phase drive currents, letting motion controllers command precise torque and speed profiles in industrial robots, pick-and-place gantries, and feeder axes. By coordinating motor phases and real-time feedback, the unit functions as the power stage that closes the torque loop inside an automation cell.
An output ceiling of 600 A is the maximum instantaneous motor current the amplifier can deliver, while the main circuit requires a 280 VDC supply from the plant’s rectifier. Internal cooling fans are energized from a separate 200 VAC line, so airflow remains stable even if the DC bus sags during transients. The command interface uses torque control, meaning upstream devices transmit a proportional torque reference rather than velocity or position data. Frequency characteristics reach 400 Hz when the load inertia equals the motor inertia, giving the drive adequate bandwidth for high-speed correction. For speed-mode operation, the velocity control span is rated at 1:3000, allowing slow jogs and rapid moves without losing resolution. A dynamic brake is not installed, so regenerative energy must be handled by external resistors or the shared bus.
The enclosure weighs 27.0 kg and includes an M8 eye bolt to simplify overhead lifting into control cabinets. Power cables attach with M10 screws tightened to 2.5 N·m, while signal wiring uses M4 hardware secured to 1.2 N·m; these specified torques help prevent heat buildup from loose terminations. Position feedback is accepted through an ABS-RII (8192 P/R) sensor, enabling high-resolution commutation without separate limit switches. A 2 G shock rating protects internal components against impacts caused by cabinet door movement or equipment handling.
