(See the table in section 4-1 for details.) (2)Higher performance than previous model. ・CDBR Transistor Short Detection:
Even in case of braking resistor shot-circuit, CDBR braking unit can be protected. ・Braking activation voltage level with 10 switching steps:
Braking activation voltage can be setting more in detail. ・Prevention of faulty wiring:
Terminal board for main circuit and control circuit are separated to prevent faulty wiring. ・Compliant with UL(RU), CE, RoHS
