The Yaskawa inverter drive board ETC710621.M is not an independent product, and its parameters need to be determined comprehensively based on the inverter model and control requirements. However, its core functional characteristics can be inferred based on the general design of Yaskawa drive boards and similar product parameters as follows:
1、 Core control function
PWM pulse generation: Using specialized chips such as SG3525A to generate high-frequency PWM pulses, the output frequency range may be between 20KHZ-60KHZ, with pulse intervals of 180 degrees, and adjustable dead time to ensure safe driving of IGBT modules.
Full bridge inverter control: Integrated full bridge inverter IGBT drive circuit, supporting frequency converter applications with power range of 10KW-120KW, suitable for high-frequency power conversion scenarios such as induction heating.
2、 Communication and Interface
Bus compatibility: It may support industrial bus standards such as Profibus DP, with communication rates ranging from 9.6kBit/s to 12MBit/s, and speed configuration can be achieved through dip switches or automatic recognition.
Fiber optic transmission options: Provides multimode (850nm/1310nm) and single-mode (1310nm/1550nm) fiber optic interfaces, with transmission distances ranging from 2Km (multimode) to 20Km (single-mode), compatible with standard interfaces such as SC/FC/ST.
3、 Protection mechanism
Electrical protection: equipped with 4000V lightning protection, 1.5A overcurrent protection, and 600W surge absorption capability to prevent damage to the drive board caused by abnormal power supply side.
Status feedback: Integrated overcurrent, overvoltage, water shortage and other status indication interfaces, supporting switch type/linear Hall sensor access, real-time monitoring of IGBT module operation status.
4、 Power supply design
Multi channel power supply: Three AC dual 18V/1A and four 22V/0.5A independent power modules are used to provide isolated power supply for the drive circuit, control logic, and communication interface, reducing power supply noise interference.
