Product Description:

The PY0A030E0XXXP00 is an exceptional performance Servo amplifier made for industrial automation tasks that need accurate motor control and energy management that reuses energy. Because of its energy-absorbing capabilities and dynamic brake response time, the amplifier is capable of handling loads with a great deal of inertia.

Major power terminals (R, S, T, U, V, W) and the control input (r) both use 2.0 mm² wiring, whereas the other type of electrical link is 1.25 mm². Encoder (CN2) and I/O (CN1) connections should use twisted pair insulated wire (0.2 mm² minimum) to reduce electromagnetic interference and maintain signal integrity. For system status monitoring, the amplifier features AMP-ready outputs (RDY1, RDY2), and for heat protection, it provides external thermostat inputs (H1, H2) with 0.5 mm² wiring. An additional earth terminal (E) that requires 2.0 mm of grounding ensures safety. The amplifier can accept external resistors with a power rating of up to 600 W, and it comes with a regenerative resistor measuring 50 Ω and 20 W. Because of this, power dissipation in demanding tasks can be enhanced.

As a main circuit rush current of 18 A (600 ms duration), the PY0A030E0XXXP00 amplifier can handle changing power conditions. The amplifier also has a control circuit surge of 40 A (1 ms duration). Its external regenerative resistor terminals (COM, Y) allow for high power dissipation, and its small size makes the best use of the control panel room. The amplifier's 6.5 ms brake delay and 360 J immediate energy absorption make sure that it can stop reliably, even at high speeds. The PY0 amplifier is efficient and reliable for advanced motion control systems because it can handle a lot of power and stop quickly.

Frequently Asked Questions about PY0A030E0XXXP00:

Q: Why does PY0A030E0XXXP00 use a 50 Ω resistor?

A: It safely dissipates regenerative energy generated during braking cycles. The internal resistor is rated for 20 W continuous power dissipation.

Q: Does PY0A030E0XXXP00 allow external regenerative resistors?

A: Yes, external resistors up to 600 W can be connected. This supports high-power braking demands in larger applications.

Q: How fast is the dynamic brake response?

A: The braking circuit activates within 6.5 milliseconds. This ensures rapid deceleration and enhances motion control safety.

Q: Do signal terminals require shielded wiring?

A: CN1 and CN2 require twisted shielded pairs for wiring. This helps reduce electrical noise and signal interference.

Q: Why is the rush current limited to 18 A?

A: The inrush current is limited to protect internal components. This 18A surge lasts only 600 milliseconds during startup.
