Product Description:

The PY2A015A3 is a servo amplifier produced by Sanyo Denki within the PY Super BL Servo Amplifiers series. In industrial automation, this device supplies controlled current to a compatible brushless servo motor. It supports closed-loop velocity or position control on single-axis stages and compact handling equipment, allowing the connected motor to follow commands while correcting motion errors through feedback.

The power stage is rated for a continuous output of 15 A, so the drive can supply moderately sized motors without external boosters. Both the main and control inputs accept single-phase 200–230 VAC at a mains frequency of 50/60 Hz, simplifying cabinet wiring where a compatible supply is available. A built-in dynamic brake provides rapid deceleration without requiring an external braking module. The unit does not include a regeneration resistor, so excess energy returning from the motor must be handled by a separate resistor bank. Servo response has a bandwidth of 400 Hz when the load inertia equals the motor inertia, supporting fast settling in pick-and-place or registration drives. Velocity can be adjusted across a 1:5000 control range, which permits the same motor to perform slow alignment moves and fast indexing with consistent drive tuning.

The amplifier weighs 1.5 kg, easing installation on suitable mounting rails or slide-out trays. It may be installed in machines operating at altitudes up to 1000 m above sea level. The unit tolerates ambient humidity up to 90% RH without condensation, helping protect normal operation in humid industrial areas. Continuous operation is permitted from 0 to 55 °C, while the electronics can be stored from -20 to +65 °C during transport or maintenance shutdowns. The amplifier does not provide an Rdy output relay, so the motion controller must monitor the DC bus, servo-on signal, or another available status signal.
