EMC and leakage currents Propagation Measures Path 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 drive unit or when their signal cables are run near the drive unit, the devices may malfunction due to air-propagated electromagnetic noises.
EMC and leakage currents 3.1.3 Power supply harmonics The drive unit 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. Take the following countermeasure suppression techniques.

Inspection items The drive unit is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.
Inspection items 6.1.4 Display of the life of the drive unit parts The self-diagnostic warning is output when the life span of each part such as the control circuit capacitor, the cooling fan, or the inrush current limit circuit is near its end. It gives an indication of replacement time. The life alarm output can be used as a guideline for life judgement.
Inspection items 6.1.5 Checking the drive unit and converter modules <Preparation> (1) Disconnect the external power supply cables (R/L1, S/L2, T/L3) and motor cables (U, V, W). (2) Prepare a tester. (Use 100 range.) <Checking method> Change the polarity of the tester alternately at the drive unit terminals R/L1, S/L2, T/L3, U, V, W, P/+ and N/-, and check for electric continuity.
Inspection items 6.1.7 Replacement of parts The drive unit consists of many electronic parts such as semiconductor devices. The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced performance or fault of the drive unit. For preventive maintenance, the parts must be replaced periodically. Use the life check function as a guidance of parts replacement.

Inspection items Reinstallation 1) After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of "AIR FLOW" faces up. AIR FLOW <Fan side face> 2) Reconnect the fan connectors. 3) When wiring, avoid the cables being caught by the fan. 4) Reinstall the fan cover.
Inspection items (2) Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc.
Measurement of main circuit voltages, currents and powers Measurement of main circuit voltages, currents and powers Since the voltages and currents on the drive unit power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured.

Measurement of main circuit voltages, currents and powers 6.2.1 Measurement of powers Use electro-dynamometer type meters (for inverter) for the both of drive unit input and output side. Alternatively, measure using electrodynamic type single-phase wattmeters for the both of drive unit input and output side in two-wattmeter or threewattmeter method.
Measurement of main circuit voltages, currents and powers 6.2.3 Measurement of currents Use moving-iron type meters on the input side of the drive unit, use approximate effective-value rectifier type AC ammeter on the output side. Since current on the drive unit input side tends to be unbalanced, measurement of three phases is recommended. Correct value can not be obtained by measuring only one or two phases.
Measurement of main circuit voltages, currents and powers 6.2.7 Measurement of drive unit output frequency A pulse train proportional to the output frequency is output across the frequency meter signal output terminal FM-SD of the drive unit. This pulse train output can be counted by a frequency counter, or a meter (moving-coil type voltmeter) can be used to read the mean value of the pulse train output voltage.

Specifications of the dedicated PM motor [MM-GKR motor] X indicates the direction of the motor's output shaft, and Y indicates the direction vertical to the motor's output shaft. Usually, the indicated value is of the non-load side bracket where the vibration is the greatest. Bearing is subject to fretting while the motor is stopped.
Specifications of the dedicated PM motor [MM-GKR motor] This value is a value at the shaft of the motor with a reduction gear. If the value exceeds the described value, please contact your sales representative. The reduction gear efficiency differs depending on the reduction ratio. Additionally, the reduction gear efficiency varies depending on operating conditions, such as the output torque, rotation speed, and temperature.
