Q: What do the V and B suffixes in VB0 represent in terms of hardware configuration?
A: The last digit V indicates that the printed circuit board has a three-proof protective coating; B indicates that the model comes standard with STO safe torque shutdown hardware; 0 indicates that the basic firmware configuration does not have an additional panel pre-installed.
Q: Compared to SX0 with the same power rating, what are the differences in safety aspects during installation and commissioning?
A: VB0 comes with an independent STO safety terminal X80, which can be directly connected to a safety relay to achieve safe shutdown; SX0 has no hardware STO point, and safe shutdown can only be achieved by software-based free shutdown, which cannot reach the PLd safety level; in addition, the VB0 coating board has stronger environmental adaptability and a lower failure rate in high and low temperature condensation environments.
Q: Does the safety STO circuit of this model require an external power supply, and what is the fault diagnosis logic?
A: STO is a hardware power circuit cutoff, requiring no auxiliary control power supply; when both STO terminals are disconnected simultaneously, the IGBT output torque is immediately blocked; a single disconnection will report a safety fault code, and the inverter will be locked and prohibited from operation. Before resetting, the wiring and safety components must be checked.
