D71 is a wall-mounted inverter, the power range is 0.75KW-500KW, the voltage level of the incoming line voltage is 380V-480V, and the control method is vector control without speed sensor. D71 has a wealth of control devices, including 8 digital inputs (LI1-LI8), 2 analog inputs (AI), 2 relay outputs (TA), 2 analog outputs (AO), 5V auxiliary power supply for analog power supply The fixed input 24V auxiliary power supply is used for digital input, and all LI/TA, AI/AO can be freely programmed to define functions.

MODBUS interface is standard configuration of D71, no option is required. The QD6600 can be connected to a higher-level automation system through MODBUS.
