Product Description:

Sanyo Denki makes the PY0A030A0MA1S01 servo motor, which is used in devices that control motion. The motor is set up to accept a single-phase input and can work with 200V AC. It has a dynamic stopping system built in that lets you slow down gradually.

The rated current consumption of the PY0A030A0MA1S01 servo motor is 30 A, which is enough power for standard load uses. It comes with an incremental encoder that saves wiring and sends 2000 pulses per turn. The type of encoder allows closed-loop motion control systems to do the basic input they need. The PY0A030A0MA1S01 doesn't work with request signals because it has an absolute encoder that doesn't work with them. This means that it can only track basic movements and not change based on signals. Position-dependent robotic systems can work with the motor because it supports encoders. The motor has a speed control interface that works with systems that need to change the speed in real time based on signals from outside the system. Between 0°C and 55°C is the temperature range that the motor can work in. The temperature range can be expanded from –20°C to 65°C when stored properly. It's made for places where the humidity level stays between 20% and 90%. To keep the unit working within its rated temperature range for a long time, it must be placed in a well-ventilated area that is free of corrosive or explosive gases.

The PY0A030A0MA1S01 servo motor is specifically engineered for industrial automation systems that require high-quality stopping power and encoder input. The motor comes with an interface speed control system that keeps the motor's behavior stable when the load changes. The servo motor can be used in closed-loop devices that have restrictions for feedback and changing speed.

Frequently Asked Questions about PY0A030A0MA1S01:

Q: Why does PY0A030A0MA1S01 use a 30A current?

A: The 30A current ensures sufficient power delivery that supports motor load demands during dynamic speed changes and braking cycles.

Q: Does PY0A030A0MA1S01 feature dynamic braking function?

A: Yes, it includes a built-in dynamic brake that assists in stable deceleration and prevents overshooting during rapid stop operations.

Q: Why does PY0A030A0MA1S01 have 2000 P/R encoder?

A: The 2000 pulses per revolution encoder ensures accurate feedback and allows fine resolution speed adjustments in motion control systems.

Q: How does PY0A030A0MA1S01 operate under high humidity?

A: It supports up to 90% ambient humidity that allows consistent operation in moisture-prone environments without internal circuit degradation.

Q: Why is PY0A030A0MA1S01 limited to 55°C ambient?

A: The 55°C upper limit protects the motor insulation and encoder stability that ensures long-term operation within its thermal tolerance.
