CT100G Series Inverter
Safety precautions
Keep the signal cables of the inverter away from the power cables as far as
»
possible, or distribute the two categories of cables vertically-crossed if the
distance is not far enough, otherwise it may cause signal interference.
» Ensure that all the screws are tightened when wiring, otherwise damage to
the inverter may occur.
» The encoders and sensors should be applied with the shielded cables and
the shielded layer should be grounded reliably.
Operation
» Confirm that the wiring is completed and correct and then cover the plate
before power on.
» Do not open the plate after power on, otherwise electric shock may occur.
» Operate the inverter appropriately, otherwise damage to the inverter may
occur.
» Non-professionals are not allowed to test the signals when the inverter is
running. Otherwise, physical injury or damage to the devices may occur.
» Do not change the parameters of the inverter at random, otherwise damage
to the inverter may occur.
» Do not touch the fans and brake resistors, otherwise it may cause
mechanical injury or burn.
» Do not start up or stop the inverter by power on or off, otherwise damage to
the inverter may occur.
» Ensure that the circuit breakers or contactors at the output sides of the
inverter are not in output state before switching, otherwise damage to the
inverter may occur.

  • Page 61: Chapter 5 Communication Protocol

    CHAPTER 5 COMMUNICATION PROTOCOL CHAPTER 5 COMMUNICATION PROTOCOL The CT100G series inverters provide RS485 communication interface. You can realize centralized control via PC/PLC (set the run commands and function parameters of the inverter, read the work state and fault information of the inverter) to meet the specific requirements.
  • Page 62 5. Communication data format The Modbus protocol communication data format of CT100G series inverters is as follows: In RTU mode, the minimum interval time should be at least 3.5 bytes for message transmission, which is the easiest way to achieve a variety of character time at the baud rate.
