Page 6: Wiring Precautions
Transportation Precautions Caution Do not hold by front cover or panel, instead, hold by the radiation fin (heat sink) while transporting the product. Doing so may result in injury. Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc- tion.
Page 7 Caution Install external breakers and take other safety measures against short-circuiting in external wiring. Not doing so may result in fire. Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup- ply voltage. An incorrect power supply may result in fire, injury, or malfunction. Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.
Page 8 WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while the RUN signal is turned ON may result in injury. Caution Be sure to confirm permissible ranges of motors and machines before operation be- cause the Inverter speed can be easily changed from low to high.

Page 43 Chapter 2 Design • A load can be started and stopped by opening and closing the magnetic contactor on the primary side. Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down. In order not to shorten the service life of the Inverter’s internal relays and electrolytic capacitors, it is recommended that the magnetic contactor is used in this way no more than once every 30 min- utes.
Page 44 Chapter 2 Design H Wiring on the Output Side of the Main Circuit D Connecting the Terminal Block to the Load Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W. Check that the motor rotates forward with the forward command. Switch over any two of the output ter- minals to each other and reconnect if the motor rotates in reverse with the forward command.
Page 45 Chapter 2 Design Induction Noise: Electromagnetic induction generates noise on the signal line, causing the con- troller to malfunction. Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting ra- dio receiver to make noise. D Countermeasures against Induction Noise As described previously, a Noise Filter can be used to prevent induction noise from being generated on the output side.
Page 46: Ground Wiring
Design Chapter 2 Also, adjust the carrier frequency (set in n46) according to the cable length between the Inverter and the motor, as shown in the following table. Cable length 50 m or less 100 m or less More than 100 m Carrier frequency 10 kHz max.
Page 47 Design Chapter 2 • When using more than one Inverter, be careful not to loop the ground wire. H Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from indus- trial machines has been causing problems recently. The Ministry of International Trade and Industry provided some guidelines in September 1994 for the suppression of harmonics from electrical household appliances and electri- cal equipment in Japan.
Page 48 Chapter 2 Design The following frequencies are harmonics of a 60- or 50-Hz commercial power supply. Second harmonic: 120 (100) Hz Third harmonic: 180 (150) Hz Second harmonic (120 Hz) Basic frequency (60 Hz) Third harmonic (180 Hz) Problems Caused by Harmonics Generation The waveform of the commercial power supply will be distorted if the commercial power supply contains excessive harmonics.
Page 49 Design Chapter 2 Inverter The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine. Voltage Time Rectified...
Page 50 Chapter 2 Design D Countermeasures with Reactors against Harmonics Generation DC/AC Reactors The DC reactor and AC reactor suppress harmonics and currents that change suddenly and greatly. The DC reactor suppresses harmonics better than the AC reactor. The DC reactor used with the AC reactor suppresses harmonics more effectively.

Page 240 Using the Inverter for a Motor Chapter 11 H Using Inverter for Existing Standard Motor When a standard motor is operated with the Inverter, a power loss is lightly higher than when operated with a commercial power supply. In addition, cooling effects also decline the low-speed range, resulting in an increase in the motor tem- perature.
Page 241: Synchronous Motor
Chapter 11 Using the Inverter for a Motor D Noise Noise is almost the same as when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz). H Using Inverter for Special Motors D Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors.
Page 242 Using the Inverter for a Motor Chapter 11 H Motor Burnout Caused by Insufficient Dielectric Strength of Each Phase of Motor Surge occurs among the phases of the motor when the output voltage is switched. If the dielectric strength of each phase of the motor is insufficient, the motor may burn out. The dielectric strength of each phase of the motor must be higher than the maximum surge voltage.
