Safety-compliant inverters (Built-to-order)
Fuji safety-compliant inverters comply with the machine safety standards EN 954-1 Cat3, and EN ISO
13849-1 PL:d Cat3 and IEC/EN 61800-5-2. This type enables easy compliance of your machines with the
safety standards.
By using a safety-compliant inverter, main circuit switches can be simplified. The circuit cuts output with
hardware, dispensing with software, and is redundantly designed with two systems.
1. By using a safety-compliant inverter, main circuit switches can be simplified.
When a safety signal is input (safety terminal: open), the inverter immediately shuts off the torque (cuts
output). The number of contacters to be used can be reduced.
