  • Page 27: Installation Of The Inverter And Enclosure Design

    Installation of the inverter and enclosure design Installation of the inverter and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter unit uses many semiconductor devices.
  • Page 28 Installation of the inverter and enclosure design Humidity Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown.
  • Page 29: Cooling System Types For Inverter Enclosure

    Installation of the inverter and enclosure design Vibration, impact The vibration resistance of the inverter is up to 5.9 m/s (2.9 m/s or less for the FR-F840-04320(185K) or higher) at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.

Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.

Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output frequency and load.

  • Page 156 Speed control under PM motor control Adjusting the speed control gain manually • The speed control gain can be adjusted for the conditions such as abnormal machine vibration, acoustic noise, slow response, and overshoot. • Pr.820 Speed control P gain 1="25% (initial value)" is equivalent to 50 rad/s (speed response of a single motor). (Equivalent to the half the rad/s value with the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.)

  • Page 467: Message Format

    (N) Operation via communication and its settings 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 468 (N) Operation via communication and its settings Message frame (protocol) • Communication method Basically, the master sends a Query message (question), and slaves return the 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), bit7 (= 80 h) of the Function Code is turned ON, and the error code is set at Data Bytes.
