Wiring 2-2-4 Chapter 2-2 Wiring around the Main Circuit Wire Size, Terminal Screw, Screw Tightening Torque, and Molded-case Circuit Breaker Capacities For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables. If any cable is long and may cause voltage drops, increase the wire size according to the cable length.

Wiring Chapter 2-2 Wiring on the Input Side of the Main Circuit Installing a Molded-case Circuit Breaker Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded case circuit breaker (MCCB) suitable to the Inverter. • Install one MCCB for every Inverter used. • Choose an appropriate MCCB capacity according to the Circuit breaker capacity column in the table on the previous page.
Wiring Chapter 2-2 Connecting Input Power Supply to the Terminal Block Input power supply can be connected to any terminal on the terminal block because the phase sequence of input power supply is irrelevant to the phase sequence (R/L1, S/L2, and R/L3).
Wiring Chapter 2-2 Wiring on the Output Side of the Main Circuit 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 terminals to each other and reconnect if the motor rotates in reverse with the forward command. Never Connect a Power Supply to Output Terminals Never connect a power supply to output terminals U/T1, V/T2, or W/T3.
Wiring Chapter 2-2 Countermeasures against Induction Noise As described previously, a Noise Filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise. Power supply MCCB CIMR-J7AZ Metal pipe VARISPEED 30 cm min.
Wiring Chapter 2-2 Ground Wiring • Always use the ground terminal with the following ground resistance: 200-V Inverter: 100 W or less 400-V Inverter: separate ground,10 W or less • Do not share the ground wire with other devices such as welding machines or power tools. • Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Inverter.
Wiring Chapter 2-2 Harmonics ■ Definiton Harmonics consist of electric power produced from AC power and alternating at frequencies that are integral multiples of the frequency of the AC power. The following frequencies are harmonics of a 60- or 50-Hz commercial power supply.
Wiring Causes of Harmonics Generation Chapter 2-2 Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC power. Such AC power, however, contains harmonics due to the difference in current flow between DC and AC. Obtaining DC from AC Using Rectifiers and Capacitors DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and smoothing the pulsating one-side voltage with capacitors.
Wiring Chapter 2-2 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. The input power factor of the Inverter is improved by suppressing the harmonics of the input current of the Inverter.
Wiring 2-2-5 Chapter 2-2 Wiring Control Circuit Terminals A control signal line must be 50 m maximum and separated from power lines. The frequency reference must be input into the Inverter through shielded, twisted-pair wires. Wiring of Control I/O Terminals Wire each control I/O terminal under the following conditions. Wires and Tightening Torque Multi-function Contact Output (MA, MB, and MC) Terminal Tightening Wire Wire size screw size torque N•m M3 0.5 to 0.6 Single wire 0.5 to 1.
Wiring Chapter 2-2 Wiring Method 1. Loosen the terminal screws with a thin-slotted screwdriver. 2. Insert the wires from underneath the terminal block. 3. Tighten each terminal screw firmly to a torque specified in the previous tables. Note 1. Always separate the control signal line from the main circuit cables and other power cables. 2. Do not solder the wires to the control circuit terminals. The wires may not contact well with the control circuit terminals if the wires are soldered. 3.
Wiring 2-2-6 Chapter 2-2 Conforming to EC Directive The following description provides the wiring method of the Inverter to meet DC Directive requirements. If the following requirements are not satisfied, the whole equipment incorporating the Inverter will need further confirmation.
Wiring Chapter 2-2 Wiring the Power Supply Make sure that the Inverter and Noise Filter are grounded together. • Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a dedicated Noise Filter. • Reduce the length of the ground wire as much as possible. • Locate the Noise Filter as close as possible to the Inverter. Make sure that the cable length between the Noise Filter and the Inverter does not exceed 40 cm. • The following Noise Filters are available.
Wiring Grounding the Shield Chapter 2-2 In order to ground the shield securely, it is recommended that a cable clamp be directly connected to the ground plate as shown below. Ground plate Cable clamp Cable Shield LVD Conformance • Always connect the Inverter and power supply via a molded case circuit breaker (MCCB) suitable to the Inverter for protecting the Inverter from damage that may result from short-circuiting. • Use one MCCB per Inverter. • Select a suitable MCCB from the following table.

Using the Inverter for a Motor Chapter 11 Using the Inverter for a Motor 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 temperature. Therefore, motor torque should be reduced in the low speed range. The following figure shows allowable load characteristics of a standard motor.
Using the Inverter for a Motor Chapter 11 H Using Inverter for Special Motors Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped. Otherwise, the overvoltage protective or overcurrent protective mechanism will be actuated, resulting in an error.
