Page 30: Peripheral Devices
NOTE • To prevent an electric shock, always earth (ground) the motor and inverter. • Do not install a power factor correction capacitor, surge suppressor, or capacitor type filter on the inverter's output side. Doing so will cause the inverter shut off or damage the capacitor or surge suppressor. If any of the above devices is connected, immediately remove it.

Page 38: 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 39 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 40  Vibration, impact The vibration resistance of the inverter is up to 5.9 m/s (2.9 m/s or less for the FR-A840-04320(160K) 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.

 Arrangement of the ventilation fan and inverter Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance.
Page 46  Mount point change of installation frame from the rear to the front The upper and lower installation frames are attached on the inverter (one for each position). Change the mount point of the upper and lower installation frames from the rear to the front as shown in the figure. When reattaching the installation frames, make sure that the installation orientation is correct.

Page 135: 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 252 NOTE • Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.  Setting the torque limit values during acceleration/deceleration individually (Pr.816, Pr.817) • The torque limit during acceleration and deceleration can be set individually. Torque limit using the setting values of Pr.816 Torque limit level during acceleration and Pr.817 Torque limit level during deceleration is as follows.
Page 253 • Use Pr.85 Excitation current break point to change the low-speed range, and use Pr.86 Excitation current low-speed scaling factor to change the torque in the low-speed range. When Pr.85 = "9999 (initial value)", a predetermined frequency is used. When Pr.86 = "9999 (initial value)", a predetermined scaling factor is used (refer to page 711).
Page 254 • When a high load is applied and the torque limit is activated under speed control or position control, the motor stalls. At this time, if a state where the rotation speed is lower than the value set in Pr.865 Low speed detection and the output torque exceeds the level set in Pr.874 OLT level setting continues for 3 seconds, Stall prevention stop (E.OLT) is activated and the inverter output is shut off.

Page 258  Adjusting the speed control gain manually (Pr.819 = "0" No easy gain tuning) • The speed control gain can be adjusted for the conditions such as abnormal machine vibration, acoustic noise, slow response, and overshoot. • Setting 60% (initial value) in Pr.820 Speed control P gain 1 is equivalent to 120 rad/s (speed response of a single motor). (Equivalent to the half the rad/s value during Real sensorless vector control or with the FR-A820-03800(75K) or higher and the FR-A840-02160(75K) or higher during Vector control.) Setting this parameter higher speeds up the response, but setting this too high causes vibration and acoustic noise.
Page 259 Movement / condition Adjustment method Set Pr.820 and Pr.821 higher. If acceleration is slow, raise the setting by 10% and then set the value to 80 to 90% of the Pr.820 Load inertia is too high. setting immediately before vibration/noise starts occurring. If overshoots occur, set about 80 to 90% of the maximum value without overshooting while Pr.821 increasing the setting value by twice.
Page 260  Compensating the speed control P gain in the constant output range (Pr.1116) • In the constant output range (rated speed or higher), the response of speed control is reduced due to weak field. Thus, the speed control P gain is needed to be compensated using Pr.1116 Constant output range speed control P gain compensation.
Page 261 • To input the X44 signal, set "44" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the function to a terminal. • The shock of P/PI control switchover is absorbed by setting Pr.1115 Speed control integral term clear time. When the X44 signal is turned ON, integration is stopped and the accumulated integral term is reduced and cleared according to the setting of Pr.1115 Speed control integral term clear time (initial value is 0 ms).

Page 689  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 690  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.

Page 902 FR-A800/A800 Plus Series Instruction Manual Supplement Emergency drive Magnetic flux Sensorless Sensorless Sensorless Magnetic flux Magnetic flux This function is used in case of emergency such as a fire to forcibly continue inverter operation to drive a motor without activating protective functions even if the inverter detects a fault. Using this function may cause damage of the motor or the inverter because driving the motor is given the highest priority.

Page 906  Emergency drive operation selection (Pr.523, Pr.524) • Use Pr.523 Emergency drive mode selection to select the emergency drive operation. Set a value in the hundreds place to select the operation when a valid protective function is activated (critical fault) during emergency drive.
Page 907  Electronic bypass during emergency drive (Pr.136, Pr.139, Pr.57) • For selecting the commercial mode (Pr.523 = "3[][], 4[][]"), setting is required as follows. Set Pr.136 MC switchover interlock time and Pr.139 Automatic switchover frequency from inverter to bypass operation and assign MC2 and MC3 signals to output terminals.
