FAQ:
1.22A-B4P5N104 What is the function of the built-in braking IGBT? Is an external braking resistor required?
- Braking IGBT: conducts regenerative current to prevent bus overvoltage and ensure smooth deceleration/stop.
- External braking resistor: not required for light load and long deceleration time (≥10-20 seconds); external braking resistor for heavy load, rapid deceleration/frequent start and stop (connect to P+/PB terminal, match resistance power).
2.What control methods and operating modes does 22A-B4P5N104 support?
Control method:
- Sensorless Vector Control (SVC)
- V/Hz control
operating mode:
- local keyboard control
- External analog control (0–10V/4–20mA)
- External digital/RS485 Modbus control
- composite control
3.22A-B4P5N104 Is the wiring and programming fully compatible with the discontinued replacement model 25A-B5P0N104?
- Wiring: The main circuit (power supply, motor, braking resistor) terminals are compatible and can be directly reused; digital/analog I/O and communication terminals have the same definition, no need to change the wiring.
- Program: Basic control parameters can be imported, but new functions (such as EtherNet/IP) need to be adapted, and some parameters need to be fine-tuned, so they are not completely compatible without modification.
