Modbus RTU drives
The DDS5x series stepper motor drives allow an accurate and complete motor control through the industrial Modbus RTU protocol.

The physical layer is RS485 type and isolated from the auxiliary and power supply, the communication speed reaches 921.600Kbit/s. Among the implemented functions is the 23 0x17 Read/Write Multiple registers which allows in a single transaction to read and write multiple registers at the same time and can be used, for example, to update the position set point and read the encoder quota in a single operation.
