Product Description:
Sanyo Denki developed this latest model PY2E030A3 which is an optimal choice for light to medium duty applications requiring robust 1000 W output. This PY Super BL Servo Amplifier’s common automation cycle requirements are matched with rated revolution speed of 3000 rpm, and enabling the same throughput over time. For speeding up motion profiles during brief bursts of higher speeds, the model is expanded to maximum revolution speed of 4500 RPM. Under standard industrial loads, a rated torque of 3.19 Nm allows precise placement.
Avoiding a drift during pauses, static loads are held firmly by the drives 3.92 N·m continuous stall torque. The instantaneous maximum stall torque of 10.3 Nm is driven by the component that overcomes abrupt load surges. The module’s rated armature current of 6.9 Arms limits power draw under normal operation and reduces electrical stress. For increasing performance without thermal shutdown, the 8.0 Arms showing continuous stall armature current sustains torque under prolonged loads. The abrupt acceleration needs are also fulfilled with a high peak current supplied by the amplifier's instantaneous maximum stall armature current of 23.2 Arms. It makes maintenance easier and ensures a consistent torque per ampere with a torque constant of 0.53 N·m/Arms.
By stabilizing back-EMF feedback, an induced voltage constant of 18.6 V/krpm enhances closed-loop speed control. PY2E030A3’s phase armature resistance of 0.51 Ω limits voltage drops and helps to preserve torque accuracy. The device with an electrical time constant of 11 msec allows quick current response which also increases control bandwidth. The moment of inertia with wiring of 1.55 × 10⁻⁴ kg·m²> and a drive’s weight of <<5.4 kg provides a solid base that minimizes vibration during operation. This servo module’s dimensions of 200 mm × 150 mm × 70 mm simplifies panel cutout design, required for easy integration into control cabinets.
Frequently Asked Questions about PY2E030A3:
Q: How effectively does the PY2E030A3 recover energy during deceleration?
A: The PY2E030A3 features a built‑in regenerative resistor circuit which absorbs kinetic energy during stops. The energy recovery reduces bus overvoltage and lowers overall power consumption.
Q: How does the inertia of the PY2E030A3 influence its acceleration performance?
A: The PY2E030A3’s inertia including wiring of 1.55 × 10⁻⁴ kg·m² reduces torque requirements for speed changes. The low inertia delivers rapid acceleration and minimizes settling time.
Q: What wiring specifications support the 6.9 Arms rated armature current of the PY2E030A3 module?
A: The module’s 6.9 Arms rated current requires 14 AWG wiring to handle the load safely. The correct gauge wiring prevents voltage drop and ensures consistent torque delivery.
Q: How does the induced voltage constant of the PY2E030A3 affect back‑EMF feedback?
A: The 18.6 V/krpm induced voltage constant stabilizes back‑EMF signals at varying speeds. This consistent voltage feedback enhances closed‑loop control accuracy.
Q: What impact does the 0.51 Ω armature resistance have on the PY2E030A3’s performance?
A: The amplifier’s 0.51 Ω phase resistance limits current spikes under sudden load changes. The controlled current flow preserves torque precision and prevents voltage sag.
