  • Page 50 MCCB Thermal relay Motor Power Inverter supply Line-to-line static capacitances Line-to-line leakage currents path  Countermeasure • Use Pr.9 Electronic thermal O/L relay. • If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting. Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.

  • Page 184: Message Format

     Outline • The MODBUS communication protocol was developed by Modicon for programmable controllers. • The MODBUS protocol uses exclusive message frames to perform serial communication between a master and slaves. These exclusive message frames are provided with a feature called "functions" that allows data to be read or written. These functions can be used to read or write parameters from the inverter, write input commands to the inverter or check the inverter's operating status, for example.
  • Page 185  Message frame (protocol) • Communication method Basically, the master sends a query message (inquiry), and slaves return a response message (response). At normal communication, the device address and function code are copied as they are, and at erroneous communication (illegal function code or data code), bit 7 (= H80) of the function code is turned ON, and the error code is set at data bytes.
