2. Connect the motor wiring to terminals U/T1, V/T2 and W/T3 on the main circuit output side (bottom of the Inverter)

3. If the wiring distance between Inverter and motor is long, reduce the

Inverter carrier frequency. For details, refer to Reducing Motor

Noise or Leakage Current Using Carrier Frequency Selection (n46) on page 64.

4. Control wiring must be less than 50 m in length and must be separated from the power wiring. Use shielded twisted-pair cable when inputting the frequency signal externally.

5. Tighten the screws on the main circuit and control circuit terminals.

6. Do not connect or disconnect wiring, or perform signal check while the power supply is turned ON.

7. For 400 V Class Inverters, always ground the supply neutral to conform to CE requirements.

8. Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals.

Additional insulation may be necessary in the end product to conform to CE requirements.

24

4. Wiring

9. Closed-loop connectors should be used when wiring to the main circuit terminals.

10.Voltage drop should be considered when determining the wire size.

Voltage drop can be calculated using the following equation:

Phase-to-phase voltage drop (V)

= Ω /km) × wiring distance (m) × current

(A) × 10 -3

Select a wire size so that voltage drop will be less than 2% of the normal rated voltage.

Full-range Automatic Torque Boost

The motor torque requirement changes according to load conditions.

The full-range automatic torque boost adjusts the voltage of the V/f pattern according to requirements. The VS mini automatically adjusts the voltage during constant-speed operation, as well as during acceleration.

The required torque is calculated by the Inverter.

This ensures tripless operation and energy-saving effects.

V/f pattern (n09 to n15).

„ Troubleshooting

Trouble

The motor does not operate when an external operation signal is input.

The motor stops. The torque is not output.

Cause

The operation method selection is wrong.

The run command (n02) is not set to

Control Circuit Terminal .

A 3-wire sequence is in effect.

The multi-function input method (n37) is set to 3-wire sequence, and the S2 control terminal is not closed.

Corrective Actions

Set the run command (n02) to

Control Circuit Terminal.

To use a 3-wire sequence, make the wiring so that the S2 control terminal is closed. To use a 2-wire sequence, set the multi-function input (n37) to a value other than 3-wire sequence.

Input a frequency reference greater than the min. output frequency (n14).

The frequency reference is too low.

The input frequency reference is lower than the setting for the min.output frequency (n14).

Local mode is in effect.

Set the LO/RE selection of the digital operator to RE.

For analog input, make sure that the frequency reference (n03) and SW8 settings are correct.

The SW setting for the reference selection is wrong.

Example: The reference 4-20 mA is input, but the SW is set to “V.”

The setting of NPN/PNP switch

(SW7) is not correct.

The stall prevention level during acceleration is too low.

Because the stall prevention level during acceleration (n56) is set too low, the output current reaches the set level, the output frequency is stopped, and the acceleration time is lengthened.

The stall prevention level during running is too low.

Because the stall prevention level during running (n57) is set too low, the output current reaches the set level, and the speed drops.

The load is too heavy.

If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened.

When the maximum frequency was changed, the maximum voltage frequency was also changed.

Set SW7 correctly.

Check if the stall prevention level during acceleration (n56) is set to an appropriate value.

Check if the stall prevention level during running (n57) is set to an appropriate value.

• Lengthen the set acceleration time

(n16).

• Reduce the load.

To increase the speed of a generalpurpose motor, only change the maximum frequency.

The V/f set value is too low.

Set the V/f (n09 to n15) according to the load characteristics.

104

8. Fault Diagnosis

Trouble

The motor speed is unstable. The motor speed fluctuates when operating with a light load.

Cause

The stall prevention level during running is too low.

Because the stall prevention level during running (n57) is too low, the output current reaches the set level and the speed drops.

The load is too heavy.

If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened.

The carrier frequency is too high.

If operating the motor with a light load, a high carrier frequency may cause the motor speed to fluctuate.

The V/f set value is too high for a low speed operation.

Because the set value for the V/f is too high, over-excitation occurs at low speeds.

The maximum frequency and base frequency were incorrectly adjusted.

Example: To operate a 60 Hz motor at

40 Hz or less, the maximum frequency and base frequency are set to 40 Hz.

The Inverter is used for an operation at 1.5 Hz or less.

Corrective Actions

Check if the stall prevention level during running (n57) is set to an appropriate value.

Reduce the load.

Decrease the carrier frequency (n46).

Set the V/f (n09 to n15) according to the load characteristics.

Set the maximum frequency and the base frequency according to the motor specifications.

Do not use the J7 Inverter for an operation that runs at 1.5 Hz or less.

For an operation at 1.5 Hz or less, use a different Inverter model.

Increase the set value for the filter time constant.

The Digital Operator does not turn ON.

The LED of the Digital

Operator is unlit.

The analog reference input is unstable and has noise interference.

The power is not being supplied.

The breaker or other component on the power input side is not turned ON, and the power is not being supplied.

Short-circuit bar for terminals

+1 and +2 is not connected.

Check if the power is being supplied.

Confirm that the short-circuit bar is connected properly.

• Ground Fault Interrupter:

Select a ground fault interrupter not affected by high frequencies. To prevent malfunctions, the current should be 200 mA or higher and the operating time 0.1 s or longer.

Example:

• NV series by Mitsubishi Electric Co., Ltd. (manufactured in 1988 and after)

• EGSG series by Fuji Electric Co., Ltd. (manufactured in 1984 and after)

• AC and DC Reactor:

Install an AC reactor to connect to a power supply transformer of large capacity (600 kVA or more) or to improve power factor on the power supply side.

• Noise Filter:

Use a noise filter exclusively for Inverter if radio noise generated from the Inverter causes other control devices to malfunction.

NOTE

1. Never connect a general LC/RC noise filter to the Inverter output circuit.

2. Do not connect a phase-advancing capacitor to the I/O sides and/or a surge suppressor to the output side.

3. When a magnetic contactor is installed between the

Inverter and the motor, do not turn it ON/OFF during operation.

For the details of the peripheral devices, refer to the catalog.

10 Conformance to CE Markings

10 Conformance to CE Markings

Points regarding conformance to CE markings are given below.

„ CE Markings

CE markings indicate conformance to safety and environmental standards that apply to business transactions (including production, imports, and sales) in Europe. There are unified European standards for mechanical products (Machine Directive), electrical products (Low Voltage

Directive), and electrical noise (EMC Directive). CE markings are required for business transactions in Europe (including production, imports, and sales).

The VS mini Series Inverters bear CE markings indicating conformance to the Low Voltage Directive and the EMC Directive.

• Low Voltage Directive: 73/23/EEC

93/68/EEC

• EMC Directive: 89/336/EEC

92/31/EEC

93/68/EEC

Machinery and installations that incorporate the Inverter are also subject to CE markings. It is ultimately the responsibility of customers making products incorporating the Inverter to attach CE markings to the finished products. The customer must confirm that the finished products

(machines or installations) conform to the European Standards.

„ Requirements for Conformance to CE Markings

† Low Voltage Directive

VS mini Series Inverters satisfy testing for conformance to the Low

Voltage Directive under the conditions described in European Standard

EN50178.

Requirements for Conformance to the Low Voltage Directive

VS mini Series Inverters must satisfy the following conditions in order to conform to the Low Voltage Directive.

• Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals.

Additional insulation may be necessary in the end product to conform to CE requirements.

129

130

• For 400 V Class Inverters, always ground the supply neutral to conform to CE requirements.

† EMC Directive

VS mini Series Inverters satisfy testing for conformance to the EMC

Directive under the conditions described in European Standard

EN61800-3.

Installation Method

In order to ensure that the machinery or installation incorporating the

Inverter conforms to the EMC Directive, perform installation according to the method below.

• Install a noise filter that conforms to European Standards on the input side. (Refer to EMC Noise Filter on page 133.)

• Use a shielded line or metal piping for wiring between the Inverter and Motor. Make the wiring as short as possible.

• For details of installation method, refer to Installation Manual (document No. EZZ008390.)
