It is recommended that you connect the inverter and motor to the power ground, and connect the upper computer separately to a ground stud.

Application of Modbus MSI350 series inverters use the RTU mode provided by the Modbus protocol, and RS485 interfaces are used. 9.3.1 RS485 RS485 interfaces work in half-duplex mode and transmit data signals in the differential transmission way, which is also referred to as balanced transmission.

The communication baud rate (P14.01) indicates the number of bits transmitted in a second, and the unit is bit/s (bps). A higher baud rate indicates faster transmission and poorer anti-interference capability.

  • Page 283 In a character frame, only the data bits carry information. The start bit, check bit, and end bit are used to facilitate the transmission of the data bits to the destination device. In practical applications, you must set the data bits, parity check bits, and end bits consistently. In RTU mode, the transmission of a new frame always starts from an idle time (the transmission time of 3.5 bytes).
  • Page 284 RTU communication frame error check modes During the transmission of data, errors may occur due to various factors. Without check, the data receiving device cannot identify data errors and may make a wrong response. The wrong response may cause severe problems. Therefore, the data must be checked. The check is implemented as follows: The transmitter calculates the to-be-transmitted data based on a specific algorithm to obtain a result, adds the result to the rear of the message, and transmits them together.

  • Page 361 Note: If the conductivity of the shield layer of the motor cables cannot meet the requirements, separate PE conductors must be used. To protect the conductors, the cross-sectional area of the shielded cables must be the same as that of the phase conductors if the cable and conductor are made of materials of the same type.
  • Page 362 For low-voltage digital signals, double-shielded cables are recommended, but shielded or unshielded twisted pairs (as shown in figure b) also can be used. For frequency signals, however, only shielded cables can be used. Relay cables need to be those with metal braided shield layers. Keypads need to be connected by using network cables.
