Connector of drive board defined(up to 75KW) Connector of drive board defined(up to 18.5KW) S3 S4-S5 谢 谢！ 放映结束 感谢各位的批评指导！ 让我们共同进步 * Ao output circuit Modbus circuit ATV71 have two RJ45 conncetor, so there is two Modbus circuit Logic input circuit P5 CPU P24 SW1 RT1N431M Input Terminal CLI C2 C1 2SA1603 2SA1603 FUSE Li6 input circuit Attention the position of SW101,one for logic input ,the other for PTC input PWR protection function To detect external fault,normally short circuit with P24V. External circuit supply +24V for PWR as warning signal.Once external circuit failure , low voltage forward to PWR,the inverter will forbid the up IGBT bridge output ,it mean forbid output.
