PY2A030A2GS1PK0
by Sanyo Denki
The PY2A030A2GS1PK0 from Sanyo Denki belongs to the PY Super BL Servo Amplifiers series and delivers a robust Rated Output (pr): 1500 W with a Rated Revolution Speed (nr): 2000 rpm. This industrial-grade servo amplifier supports applications requiring precise speed, torque, or position management. With a compact design weighing Weight (we): 16.1 kg, it integrates seamlessly into automation systems where space and reliability are critical. The amplifier achieves a Maximum Revolution Speed (nmax): 2000 rpm and maintains consistent performance under variable load conditions.
Featuring advanced power electronics, the amplifier utilizes IGBT PWM control with sine wave drive to achieve high efficiency. Its electrical behavior is characterized by an Electrical Time Constant (te): 5.3 msec and a Mechanical Time Constant (tm): 4.9 msec, ensuring rapid response to command inputs. The unit delivers a Continuous Stall Torque (ts): 8.8 N·m (90 kg·cm) at a Continuous Stall Armature Current (is): 7.9 Arms, and supports an Instantaneous Maximum Stall Torque (tp): 19.6 N·m (200 kg·cm) with a peak armature current of Instantaneous Maximum Stall Armature Current (ip): 17.9 Arms. A Torque Constant (kt): 1.34 N·m/Arms (13.7 kg·cm/Arms) and an Induced Voltage Constant (keφ): 47.0 mV/(min⁻¹) or 47.0 V/krpm provide excellent torque-to-current linearity. The amplifier’s Phase Armature Resistance (rφ): 0.84 Ω and a Rated Armature Current (ir): 6.9 Arms further enhance its electrical stability.
Operationally, the PY2A030A2GS1PK0 supports a wide input range of 3-phase 200–230 VAC ±10 % / –15 %, 50/60 Hz ±3 Hz for the main circuit and single-phase control power of the same range, providing flexibility in installation. It offers a velocity control range of 1:5000 and maintains a speed variation of ±0.1 % under load and ±0.5 % over 0 °C to 55 °C, ensuring consistent motion profiles in harsh environments. Built-in protection features include overcurrent, overload, sensor error, overspeed, regeneration error, and undervoltage lockout. The amplifier incorporates dynamic braking and regenerative processing to improve motor control reliability and energy efficiency, and a front-panel display provides real-time status and alarm reporting.
Integration is simplified by the inclusion of monitoring outputs: a velocity monitor (VMO) output of 2.0 V ±10 % at 1000 min⁻¹ and a current monitor (IMO) output of 2.0 V ±20 % at rated armature current. Command inputs accept ±2.0 V DC signals at 1000 min⁻¹ for forward rotation, allowing straightforward interfacing with PLCs and motion controllers. This model’s precise feedback capabilities, combined with its robust construction and advanced electronics, make it ideal for industrial automation tasks such as robotic positioning, conveyor indexing, packaging machinery, and CNC applications where high dynamic response and accuracy are required.
