Page 55: Emc And Leakage Currents
EMC and leakage currents EMC and leakage currents 3.1.1 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 static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Page 56 EMC and leakage currents Line-to-line leakage currents Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external thermal relay unnecessarily. When the wiring length is long (50m or more) for the 400V class small-capacity model (7.5kW or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.

EMC and leakage currents Selection of rated sensitivity current of earth (ground) leakage current breaker When using the earth leakage current breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency.  Breaker designed for harmonic and Ig1, Ig2: Leakage currents in wire path during commercial surge suppression...
Page 58: 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 59 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 malfunction due to air-propagated electromagnetic noises.
Page 60: Power Supply Harmonics
EMC and leakage currents 3.1.3 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. Take the following countermeasure suppression techniques.

Installation of power factor improving reactor Installation of power factor improving reactor When the inverter is connected near a large-capacity power transformer (500kVA or more) 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. To prevent this, always install a Filterpack or an optional AC reactor (FR-HAL).

Set parameters after confirming the function of each terminal.  When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different setting may cause a fault, failure or malfunction.
Page 261 Special operation and frequency control PID output suspension function (SLEEP function) (SLEEP signal, Pr. 575 to Pr. 577 ) The inverter stops operation if the output frequency after PID operation remains at less than the Pr. 576 Output interruption detection level setting for longer than the time set in Pr. 575 Output interruption detection time. This function can reduce energy consumption in the low-efficiency, low-speed range.
Page 262 Special operation and frequency control PID monitor function The PID control set point, measured value and deviation value can be displayed on the operation panel and output from the terminal FM. In the deviation monitor, a negative percent can be displayed as an integer, like 0% as 1000 and so on. (The deviation monitor cannot be output from the terminal FM.) For each monitor, set the following value in Pr.

Page 265 Special operation and frequency control NOTE  If the multi-speed (RH, RM, RL, REX signal) or Jog operation (JOG signal) is entered with the X14 signal ON, PID control is stopped and multi-speed or Jog operation is started.  If the setting is as follows, PID control becomes invalid. Pr.

Page 267: Regeneration Avoidance Function (Pr. 665, Pr. 882, Pr. 883, Pr. 885, Pr. 886)
Special operation and frequency control 4.21.2 Regeneration avoidance function (Pr. 665, Pr. 882, Pr. 883, Pr. 885, Pr. 886) This function detects a regeneration status and increases the frequency to avoid the regenerative status.  Possible to avoid regeneration by automatically increasing the frequency to continue operation if the fan happens to rotate faster than the set speed due to the effect of another fan in the same duct.
Page 268 Special operation and frequency control REMARKS  The acceleration/deceleration ramp while the regeneration avoidance function is operating changes depending on the regeneration load.  The DC bus voltage of the inverter is about times of normal input voltage. (However, it varies with the input power supply waveform.) When the input voltage is 220VAC, bus voltage is approximately 311VDC.
