Page 44: Emc Measures
EMC and leakage currents 3.1.2 EMC measures Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
Page 45 EMC and leakage currents Propagation Path Measures When devices that handle low-level signals and are liable to malfunction due to electromagnetic 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 electromagnetic noises.

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 50: Precautions For Use Of The Inverter
Precautions for use of the inverter 3.4 Precautions for use of the inverter The FR-A701 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 51 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 52: Failsafe Of The System Which Uses The Inverter
When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,...
Page 53 Failsafe of the system which uses the inverter 4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal. The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor. Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse signal is STR signal).
Page 54: Driving The Motor
Step of operation 4 DRIVING THE MOTOR 4.1 Step of operation The inverter needs frequency command and start command. Frequency command (set frequency) determines the rotation speed of the motor.
