Key questions and answers

Question 1: What are the core differences in power supply and usage between Gold Whistle's 100V and 200V versions?

answer:

100V version: A single DC power supply (12~95VDC) can simultaneously drive the power and control parts, making wiring simpler.

200V version: Dual power supply is required, with a main power supply (12~195VDC) and an independent control power supply (12~95VDC), providing stronger safety and anti-interference capabilities.

Question 2: What feedback types does the driver support? What functions can dual feedback interfaces achieve?

Answer: Supports incremental encoders, absolute serial encoders (EnDat/Biss/SI), sine and cosine encoders, rotary encoders, and Hall sensors. Port A is the main feedback, Port B is the second feedback, which can achieve dual loop control (motor+load dual feedback), and Port C can output simulated encoder signals to the upper system.

Question 3: What is the STO security level of Gold Whistle? What are the key requirements for wiring and usage?

Answer: STO has reached the highest levels of SIL3, PL e, and Cat.3. When in use, dual channel independent signals must be connected to ensure that a single fault does not lose its safety function; The driver has been short circuited internally, and the short-circuit wire needs to be removed and a safety relay connected when it is activated.
