Product Description:

The PV1A015SM61P50 servo amplifier is part of the PV Super Servo Amplifiers series manufactured by Sanyo Denki. It serves as the power stage between a motion controller and a permanent-magnet servo motor, converting fixed-frequency mains power into variable current that follows command profiles. In industrial automation, the unit keeps the drive axis synchronized with position commands while protecting the motor from overcurrent events. Its compact enclosure fits easily into multi-axis control cabinets.

The amplifier is rated for 15 A of continuous output, enabling it to drive low-inertia servo motors through rapid acceleration cycles without clipping the current. It accepts a single- or three-phase supply at 200 V AC, so it can be connected directly to common factory distribution panels. Rotor position is measured by a feedback encoder that delivers 2,000 P/R. This pulse count provides an angular resolution of 0.18 degrees per pulse, which is suitable for general handling and light machining axes. The encoder interface uses the Wiring-Saving Incremental protocol, which reduces the connector pin count by multiplexing the two phase signals with an index pulse. This arrangement simplifies harness construction and reduces wiring density inside the panel.

When paired with its designated motor, the amplifier supports a shaft power of 200 W, aligning its electrical capacity with the thermal limits of the motor windings. The motor has a 54 × 54 mm frame, which allows predictable mounting clearance alongside other axes. Command and diagnostic data travel over DeviceNet, allowing node addressing and cyclic updates alongside PLC I/O on the same trunk line. At power-up, the unit defaults to the position control mode, making it suitable for point-to-point indexing without additional parameter changes. This mode allows the connected axis to follow commanded target positions while encoder feedback supports closed-loop correction during movement.
