Product Description:
The PY2A015A1M81S02 is a Super BL Servo Amplifier, which is manufactured by Sanyo Denki to deliver continuous and smooth motor control under different installation situations. This amplifier has a main circuit input voltage of 200–230 VAC with +10% to -15% tolerance levels for varying supply conditions.
This amplifier delivers a three-phase output voltage of 0 to 326V, which makes it compatible with a wide variety of servo motors. The output current of 3.1A guarantees precise current control by this amplifier even during dynamic load changes. This amplifier’s onboard dynamic brake provides extra motor protection by reducing rotational energy immediately to facilitate fast deceleration and emergency braking. The PY2A015A1M81S02 amplifier operates in a temperature range of 0°C to 55°C and has a high altitude rating of 1,000 meters. The encoder compatibility for this amplifier includes wiring-saved incremental encoders (INC-E) rated at 2000 pulses per revolution (2000P/R). This amplifier also supports request signal-unavailable absolute encoders (ABS-E) to provide system designers with flexibility based on feedback type and wiring restrictions. This amplifier has a Pulse Width Modulation (PWM) frequency of 20.8 kHz to ensure high-speed switching operation.
