Page 37: 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 38 NOTE • For the amount of heat generated by the inverter unit, refer to page  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 39  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 in X, Y, and Z directions. Subjecting the product to vibration and impacts over a long period of time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.

Page 98: Power Supply Harmonics
Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Page 99 3.2.2 Harmonic suppression guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products"...

Page 102: Installation Of A Reactor
Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor correction capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this, always install an AC reactor (FR-HAL), which is available as an option.
Page 103: Power Shutdown And Magnetic Contactor (Mc)
Power shutdown and magnetic contactor (MC)  Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes. (Refer to page 28 for selection.) • To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).
Page 104 NOTE • Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open.
Page 105: Countermeasures Against Deterioration Of The 400 V Class Motor Insulation
Countermeasures against deterioration of the 400 V class motor insulation In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals.

Page 107 Refer to Check by Checkpoint Countermeasure page user When using a switching circuit as shown below, chattering due to misconfigured sequence or arc generated at switching may allow undesirable current to flow in and damage the inverter. Miswiring may also damage the inverter. (Note that a PM motor cannot be driven by the commercial power supply.) Interlock When using the electronic bypass...
Page 108 Refer to Check by Checkpoint Countermeasure page user When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or specific inverter settings (high carrier frequency and EMC filter ON).
Page 109: Failsafe System Which Uses The Inverter
Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function activates and outputs the Fault signal. However, the Fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason.
Page 110  Checking the inverter operating status by using the start signal input to the inverter and the Inverter running signal output from the inverter ... (c) The Inverter running (RUN) signal is output when the inverter is running. (The RUN signal is assigned to terminal RUN in the initial setting.) Check if the RUN signal is output while a start signal (the STF/STR signal for forward/reverse rotation command) is input to the inverter.
Page 111  Command speed and actual operation check Check for a gap between the actual speed and commanded speed by comparing the inverter's speed command and the speed detected by the speed detector.

(While the RT signal is range 9999 ON, the second function is enabled.)
Page 231 NOTE • If the acceleration/deceleration time is set, the actual motor acceleration/deceleration time cannot be made shorter than the shortest acceleration/deceleration time determined by the mechanical system J (moment of inertia) and motor torque. • If the Pr.20 setting is changed, the Pr.125 and Pr.126 (frequency setting signal gain frequency) settings do not change. Set Pr.125 and Pr.126 to adjust the gains.
Page 232 NOTE • The reference frequency during acceleration/deceleration depends on the setting of Pr.29 Acceleration/deceleration pattern selection. (Refer to page 231.) • The RT signal can be assigned to an input terminal by setting Pr.178 to Pr.189 (Input terminal function selection). Changing the terminal assignment may affect other functions.
Page 233  Linear acceleration/deceleration (Pr.29 = "0 (initial value)") • When the frequency is changed for acceleration, deceleration, etc. during inverter operation, the output frequency is changed linearly (linear acceleration/deceleration) to reach the set frequency without straining the motor and inverter. Linear acceleration/deceleration has a uniform frequency/time slope.
Page 234 NOTE • When the RT signal turns ON during acceleration or deceleration with the S-pattern acceleration/deceleration B enabled, a pattern of acceleration or deceleration changes to linear at the moment.  Backlash measures (Pr.29 = "3", Pr.140 to Pr.143) • Reduction gears have an engagement gap and have a dead zone between forward rotation and reverse rotation. This dead zone is called backlash, and this gap disables a mechanical system from following motor rotation.

Page 236  Acceleration/deceleration operation • The running frequency changes as follows when the set frequency is changed by the remote setting function. Frequency Time setting Description Set frequency Pr.44/Pr.45 The set frequency increases/decreases by remote setting according to the Pr.44/Pr.45 setting. Running frequency Pr.7/Pr.8 The running frequency increases/decreases by the set frequency according to the Pr.7/Pr.8 setting.
Page 237 NOTE • When switching the start signal from ON to OFF, or changing frequency by the RH or RM signal frequently, set the frequency setting value storage function (write to EEPROM) invalid (Pr.59 = "2, 3, 12, 13"). If the frequency setting value storage function is valid (Pr.59 = "1, 11"), the frequency is written to EEPROM frequently, and this will shorten the life of the EEPROM.
Page 238 • When the remotely-set frequency is cleared by turning ON the RL (clear) signal after turning OFF (ON) both the RH and RM signals, the inverter operates at the frequency in the remotely-set frequency cleared state if power is reapplied before one minute has elapsed since turning OFF (ON) both the RH and RM signals.

This function will be usable in a case where the inverter does not reply to external command signals during operation due to the operation mode accidentally unswitched from the PU operation mode to the External operation mode.
Page 249  Switching operation mode by external signal (X16 signal) • When External operation and the operation from the operation panel are used together, the PU operation mode and External operation mode can be switched during a stop (during motor stop, start command OFF) by using the PU/External operation switchover (X16) signal.
Page 250 When the X16 signal is OFF, the PU operation mode is selected. Also, when "0" is set for Pr.550 NET mode operation command source selection and the communication option is not connected (communication option is the command source), the PU operation mode is selected.

Page 405 5.11.1 Electronic bypass function Magnetic flux Magnetic flux Magnetic flux The inverter contains complicated sequence circuits for switching between the commercial power supply operation and inverter operation. Therefore, interlock operation of the magnetic contactor for switching can be easily performed by simply inputting start, stop, and automatic switching selection signals.
Page 406 • When switching between inverter operation and commercial power supply operation, commercial power supply may be accidentally applied to the output side of the inverter. To avoid such situation, provide an interlock where the magnetic contactor at the commercial power supply side turns ON at turn OFF of the magnetic contactor at the inverter output side. The inverter's electronic bypass sequence that outputs timing signals for the magnetic contactors can act as a complicated interlock between the commercial power supply operation and the inverter operation.
