Page 39: Enclosure Design
Enclosure design 2.1 Enclosure design When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout.
Page 40 Enclosure design (3) Dust, dirt, oil mist Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to moisture absorption of accumulated dust and dirt, and in-enclosure tempearture rise due to clogged filter. In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.
Page 41: Cooling System Types For Inverter Enclosure
Enclosure design 2.1.2 Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter.

Page 43: Precautions For Use Of The Inverter
Precautions for use of the inverter 2.2 Precautions for use of the inverter The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
Page 44 Precautions for use of the inverter (13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.
Page 45: Noise And Leakage Currents
Noise and leakage currents 2.3 Noise and leakage currents 2.3.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Page 46 Noise and leakage currents (3) Selection of rated sensitivity current of earth leakage breaker When using the earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency: ⋅ Breaker designed for harmonic and surge suppression Example of leakage current Leakage current example of Rated sensitivity current:...
Page 47: Inverter-Generated Noises And Their Reduction Techniques
Noise and leakage currents 2.3.2 Inverter-generated noises and their reduction techniques Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to be insusceptible to noises, it handles low-level signals, so it requires the following basic techniques.
Page 48 Noise and leakage currents Noise Propagation Measures Path When devices that handle low-level signals and are liable to malfunction due to noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated noises.
Page 49: Power Supply Harmonics
Noise and leakage currents 2.3.3 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Page 50: Installation Of A Reactor
Noise and leakage currents 2.4 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000kVA or more and wiring length 10m max.) or when a power capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit.
Page 51: Inverter-Driven 400V Class Motor
Noise and leakage currents 2.6 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures: Measures It is recommended to take either of the following measures:...

Page 191 Communication operation and setting (2) Outline The Modbus protocol is the communication protocol developed by Modicon for PLC. The Modbus protocol performs serial communication between the master and slave using the dedicated message frame. The dedicated message frame has the functions that can perform data read and write. Using the functions, you can read and write the parameter values from the inverter, write the input command of the inverter, and check the operating status.
Page 192 Communication operation and setting (4) Message frame (protocol) Communication method Basically, the master sends a query message (question) and the slave returns a response message (response). When communication is normal, Device Address and Function Code are copied as they are, and when communication is abnormal (function code or data code is illegal), bit 7 (= 80h) of Function Code is turned on and the error code is set to Data Bytes.
Page 193 Communication operation and setting (5) Message format types The message formats corresponding to the function codes in Table 1 on page 181 will be explained. Read holding register data (H03 or 03) Can read the description of 1) system environment variables, 2) real-time monitor, 3) alarm history, and 4) inverter parameters assigned to the holding register area (refer to the register list (page 188)).

Page 197 Communication operation and setting Error response An error response is returned if the query message received from the master has an illegal function, address or data. No response is returned for a parity, CRC, overrun, framing or busy error. CAUTION No response message is sent in the case of broadcast communication also.
