5. WIRING

• Wiring Instructions

(1) Always connect the power supply via a molded-case circuit breaker (MCCB) to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase). Never connect the power supply to U/T1, V/T2, W/T3,-,+1 or +2.

The single-phase (200V class) inverter can be connected to a 200V 3-phase input.

However, when a single-phase supply is used, never use the terminal T/L3 for other purposes.

(2) Connect the motor wiring to terminals U, V, and W 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

(n46)” on page 79.

(4) Control wiring must be less than 164ft(50m) in length and separate from the power wiring. Use twisted-pair shielded wire 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 checks while the power supply is turned ON.

inverters)

• Main Circuit Input Power Supply

Connect the power supply wiring to input terminals L1 (R), L2(S) and L3(T) [L1(R),

L2(S) for single-phase inverters]. Never connect them to U/T1, V/T2, W/T3, -, +1, or +2. Otherwise the inverter may be damaged. Single-phase voltage may be connected to inverter but do not use terminal T/L3 for any other purposes.

When several VS mini J7 units are used side by side, ground each unit as shown in examples. Do not loop the ground wires.

On Single-phase models, terminal

T/L3 is connected internally within the inverter. Never use the terminal for other purposes.

• Grounding (Use ground terminal .)

Make sure to ground the ground terminal according to the local grounding code.

Never ground the VS mini J7 to welding machines, motors, or other electrical equipment.

• Wiring the Main Circuit Terminals

Pass the cables through wiring hole and connect. Be sure to mount the cover in its original position.

Connect with a Phillips (plus) screwdriver.

42

• Recommended Peripheral Devices

It is recommended that the following periheral devices be mounted between the AC main circuit power supply and VS mini J7 input terminals R/L1, S/L2, and T/L3.

• MCCB (Molded-case circuit breaker):

A circuit breaker should be connected for wiring protection.

• Magnetic contactor:

Mount a surge suppressor on the coil (refer to the table shown below).

To assure optimum inverter life when using a magnetic contactor to start and stop

the inverter, do not exceed one stop per hour.

• Ground fault interrupter:

Select a ground fault interrupter not affected by high frequencies. To prevent malfunctions, the leakage current sensitivity should be 200mA or more and the operating time 0.1 sec. or more.

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

(600kVA 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.

• Typical setting of V/f pattern

Set the V/f pattern according to the application as described below. For 400V class, the voltage values (n10, n13, and n15) should be doubled. When running at a frequency exceeding 50Hz/60Hz, change the maximum output frequency (n09).

Note: Be sure to set the maximum output frequency according to the motor characteristics.

Increasing voltage of V/f pattern increases motor torque, but excessive increase may cause motor over excitation, motor overheat, or vibration.

59

When operating with frequency larger than 60Hz/50Hz, change only maximum output frequency (n09).

• Full-range automatic torque boost

Motor torque requirement changes according to load conditions. Full range automatic torque boost adjusts voltage of V/f pattern according to the requirement.

The VS mini J7 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.

Output voltage ∝ Torque compensation gain (n63)

×

Required torque

Operation

Normally, no adjustment is necessary for torque compensation gain (n63 factory setting: 1.0). When wiring distance between the inverter and motor is long or when motor generates vibration, change the automatic torque compensation gain. In these cases, it may also be beneficial to adjust the V/f pattern (n09 to n15).

• Switching LOCAL/REMOTE Modes

The following functions can be selected by switching the LOCAL or REMOTE mode. To select RUN/STOP commands or frequency reference, change the mode in advance depending on the following applications.

• LOCAL Mode:

Enables the digital operator for RUN/STOP commands and

FWD/REV run commands. Frequency reference can be set by

volume or

• REMOTE Mode:

61

• Selecting Run/Stop Commands

Refer to page 63 to select either the LOCAL mode or REMOTE mode.

Operation method (RUN / STOP commands, FWD / REV run commands) can be selected by the following method.

• LOCAL Mode

When Lo (local mode) is displayed on the digital operator (when is illuminated), or when the LOCAL / REMOTE changeover function is set as a multi-function input and the input terminal is turned ON, run operation is enabled by the or of the digital operator. FWD/REV is selected by illuminating and using or key to select FWD or REV.

• REMOTE mode

• Select remote mode

The following two methods are used to select remote mode:

1. Select rE (remote mode) for selection.

2. When the local / remote switching function is selected as multi-function input selection, turn OFF the input terminal to select remote mode.

• Select operation method by setting the parameter n02.

n02=0: Enables the digital operator (same with local mode)

=1: Enables the multi-function input terminal (see fig. below)

=2: Enables communications (refer to page 96)

• Example for using the multi-function input terminal as operation reference

(two-wire sequence) follows. For 3-wire sequencing, refer to page 85.

• Operating (RUN /STOP commands) by communications

(When option card is installed)

Setting parameter n02 to 2 in REMOTE mode can give RUN / STOP commands by communication (MEMOBUS). For details, refer to page 96.

62

• Selecting Frequency Reference

Frequency reference can be selected by the following methods.

• Setting by operator

Select REMOTE or LOCAL mode in advance. For the method of selecting the mode, refer to page 62.

LOCAL mode

Parameter n07 determines where the frequency reference is input from when in the local mode.

n07 =0: Enables the setting by volume on digital operator (initial setting)

Factory setting of the model with operator

(without volume) is n07=1.

=1: Enables the digital setting by digital operator, setting value is stored in parameter n21 (frequency reference 1).

• Digital setting by digital operator

Input frequency while FREF is illuminated (press ENTER after setting the desired frequency value).

Frequency reference setting is immediately effective when n08 = 1 The ENTER key does not have to be pressed to enter the reference.

n08 =0: Enables frequency reference acceptance by ENTER key.

=1: Disable frequency reference setting by ENTER key. It is not necessary to press the ENTER key to accept the reference.

REMOTE mode

Parameter n03 determines where the frequency reference is accepted from when in the REMOTE mode.

n03 =0: Enables frequency reference setting by volume on digital operator.

=1: Frequency reference 1 (parameter n21) is effective

=2: Voltage reference terminal “FR” is effective (0 to 10V)

(See the figure below)

=3: Current reference terminal “FR” is effective(4 to 20mA)

(Refer to page 90)*

=4: Current reference terminal “FR” is effective (0 to 20mA)

• Adjusting speed setting signal

The relationship between the analog input signal and internal (terminal “FR”) frequency reference can be set by parameters n41 and n42.

FREQUENCY REFERENCE

(a) Frequency reference gain (n41)

The analog input voltage level for the maximum output frequency (n09) can be set in units of 1%. (maximum output frequency n09=100%)

∗ Factory setting : 100%

(b) Frequency reference bias (n42)

The frequency reference provided when the analog input is 0V (4mA or 0mA) can be set in units of 1%. (Maximum output frequency n09=100%)

∗ Factory setting : 0%

Example settings:

• To operate the inverter with frequency reference of 0% to 100% at 0 to 5V input

Gain n41 = 200%

Bias n42 = 0%

67

68

• To operate the inverter with frequency reference of 50% to 100% at 0 to

10V input

Gain n41 = 100%

Bias n42 = 50%

Adjusting frequency upper and lower limits

Frequency reference upper (n30) and lower

(n31) limits determines the range over which the inverter will operate.

• Frequency reference upper limit (n30)

Sets the upper limit of the frequency reference in units of 1%.

(n09: Maximum output frequency = 100%)

Factory setting: 100%

• Frequency reference lower limit (n31)

Sets the lower limit of the frequency reference in units of 1%.

(n09: Maximum output frequency = 100%)

When operating at frequency reference 0, operation is continued at the frequency reference lower limit.

However, when frequency reference lower limit is set to less than the minimum output frequency (n14), operation is not performed.

Factory setting: 0%

Using two accel/decel times

* When “deceleration to a stop” is selected (n04 = 0)

Two acceleration times and two deceleration times can be selected via a multi-function input. Programming any of terminals S2 through S5 (parameter n36 to n39) to “11”

“Accel/Decel time select”, provides the ability to switch between the 2 acceleration times (n16 and n18) and deceleration (n17 and n19) through a contact closure applied to the appropriate terminal (See timing diagram above).

69

At OFF: n16 (accel time 1) are used.

n17 (decel time 1)

At ON: n18 (accel time 2) are used.

n19 (decel time 2)

• Accel time

Set the time needed for output frequency to reach 100% from 0%.

• Decel time

Set the time needed for output frequency to reach 0% from 100%.

(Maximum output frequency n09 = 100%)

Overtorque detection

If an excessive load is applied to the machine, output current increase can be detected to output alarm signals to multi-function output terminals MA and MB.

To output an overtorque detection signal, set output terminal function selection n40 to

“overtorque detection” [Setting:6 (NO contact) or 7 (NC contact)].

(1) To detect overtorque at accel/decel, set to 3 or 4.

(2) To continue the operation after overtorque detection, set to 1 or 3.

During detection, the operator displays “ ” alarm (blinking).

(3) To halt inverter by a fault at overtorque detection, set to 2 or 4. At detection, the operator displays “ ” fault (ON).

• Overtorque detection level (n60)

Sets the overtorque detection current level in units of 1%. (Inverter rated current =

100%)

Factory setting: 160%

• Overtorque detection time (n61)

If the time when the motor current exceeds the overtorque detection level (n61), the overtorque detection function operates.

Factory setting: 0.1sec.

73

Frequency detection (n58)

Effective when the multi-function output terminal MA-MB-MC (parameter n40) is set to “frequency detection” (setting: 4 or 5). “Frequency detection” turns ON when output frequency is higher or lower than the frequency detection level (n58).

• Frequency detection 1 (Output frequency > Frequency detection level n58)

(Set n40 to “4”.)

• Frequency detection2 (Output frequency < Frequency detection level n58)

(Set n40 to “5”.)

74

Jump frequencies (n49 to n51)

This function allows the prohibit or “jumping” of critical frequencies so that the motor can operate without resonance caused by machine characteristics. This function is also used for dead band control. Setting the value to 0.00Hz disables this function.

Set prohibited frequency 1, 2 or as follows: n49 > n50

If this condition is not satisfied the inverter displays for one second and restores the data to original settings.

Continuous operation is prohibited within the jump frequency range.

However, during accel/decel the output frequency ramps through the jump frequency range (without jumping).

Continuing operation by automatic fault reset (n48)

Sets the inverter to restart and reset fault detection after a fault occurs.

The number of self-diagnosis and retry attempts can be set with n48 (0 thru 10 restarts).

The inverter will automatically restart after the following faults occur:

• OC (overcurrent)

• GF (ground fault)

• OV (over voltage)

The number of retry attempts are cleared to 0 during the following cases:

(1) If no other fault occurs within 10 minutes after retry

(2) When the fault reset signal is ON after the fault is detected

(3) Input power is turned OFF

75

Starting into a rotating motor - Tripless Operation

To start into a coasting motor without trip, use the speed search command or DC injection braking at start.

• Speed search command

Speed matches into a coasting motor upon starting without stopping the motor.

This function enables smooth switching between motor commercial power supply operation and inverter operation.

Set input terminal function selection (n36 to n39) to “14” (search command from maximum output frequency) or “15” (search command from set frequency).

Build a sequence so that FWD (REV) run command is input at the same time as the search command or after the search command. If the run command is input before the search command, the search command becomes disabled.

• Time chart at search command input

• DC injection braking at start (n52, n54)

When starting into a coasting motor, use DC injection to gradually brake the motor before beginning the acceleration ramp. Set the DC injection braking time at start in n54 in units of 0.1 second. Set DC injection braking current in n52 in units of 1%

(inverter rated current = 100%). When the setting of n54 is “0”, DC injection braking is not performed and acceleration starts from the minimum output frequency.

When n52 is set to 0, acceleration starts from the minimum output frequency after base blocking for n54 setting time.

76

Accel/Decel Hold

To hold acceleration or deceleration, use a multi-function input that is set to a value of

“16: Accel/Decel Hold. The output frequency is kept constant when the accel/decel hold command is input during acceleration or deceleration.

When the run command is removed during an accel/decel hold condition, accel/decel hold is internally released and operation ramps to stop.

Set multi-function input terminal selection (n36 to n39) to 16 (accel/decel hold command).

Note: When the FWD (REV) run command is input along with the accel/decel hold command, the motor does not operate. However, when frequency reference lower limit

(n31) is set greater than or equal to minimum output frequency (n14), the motor operates at frequency reference lower limit (n31).

Description

Deceleration to stop

Coast to stop

• Deceleration to stop (n04 =0)

* When frequency reference is changed during running.

Upon removal of the FWD (REV) run command, the motor decelerates at the decel rate determined by the time set to decel time 1 (n17) and DC injection braking is applied immediately before stop. DC injection braking is also applied when the motor decelerates by setting the frequency reference lower than minimum output frequency while the(n14) with FWD (REV) run command remains ON.

If the decel time is short or the load inertia is large, an over voltage (OV) fault may occur during deceleration. In this case, increase the decel time.

82

• Coast to stop (n04=1)

* When frequency reference is changed during running.

Upon removal of the FWD (REV) run command, the motor starts coasting.

Applying DC injection braking

• DC injection braking current (n52)

Sets DC injection braking current level in units of 1%. (Inverter rated current=100%)

• DC injection braking time at stop (n53)

Sets the DC injection braking time at stopping in units of 0.1 second. When the setting of n53 is 0, DC injection braking is not performed but inverter output is shut

OFF at the timing of DC injection braking start.

When coast to a stop is selected as the stopping method selection (n04), DC injection braking at stop does not operate.

• Setting Frequency by Current Reference Input

When setting frequency by inputting current reference (4-20mA or 0-20mA) from the control circuit terminal FR, switch the DIP switch SW8 on the control circuit board to “I” side.

SW8 is accessed by removing the terminal cover.

SW8

Never input voltage reference to control circuit terminal FR when DIP switch SW8 is switched to “I” side. Damage to the inverter may result.

89

Current reference selection

After changing DIP switch (SW8) to the “I” side, PRESS PRGM on the digital operator, then set the following parameters.

4-20mA…n03 = 3

0-20mA…n03 = 4

Press the digital operator keys to run or stop the inverter. Switch run and stop direction by setting F/R LED.

• Preventing Motor from Stalling (Current Limit)

This function automatically limits the output current in response to load changes by adjusting the output frequency to prevent motor stalling.

• Stall prevention (current limit) level during acceleration (n56)

Sets the stall prevention (current limit) level during acceleration in units of 1%

(Inverter rated current = 100%).

Factory setting: 170%

A setting of 200% disables the stall prevention (current limit) during acceleration.

During acceleration, if the output current exceeds the value set for n56, acceleration stops and frequency is maintained. When the output current goes down to the value set for n56, acceleration continues.

* Stops the acceleration to prevent the motor from stalling.

† Release width (hysteresis) of stall prevention during accel is approx. 5% of inverter rated current.

*

In the constant horsepower area [output frequency > max. voltage output frequency

(n11)], following equation automatically decreases the stall prevention (current limit) level during acceleration.

*

*Note: The lower limit of the stall prevention level is 40% of the level set in n56.

91

• Stall prevention (current limit) level during running (n57)

Sets the stall prevention (current limit) level during running in units of 1% (Inverter current = 100%).

Factory setting: 160%

A setting of 200% disables the stall prevention (current limit) during running.

If the output current during speed agree exceeds the value set for n57 for longer than

100msec, deceleration starts.

As long as the output current exceeds the value set for n57 deceleration continues.

When the output current goes below the value set for n57, acceleration begins to the set frequency.

The accel/decel rates during stall prevention are determined by the accel time (n16 or n18) and decel time (n17 or n19) that is selected at the time of the stall prevention condition.

* Decreases frequency to prevent the motor from stalling.

† At acceleration start, output hysteresis is approx. 5% of inverter rated current.

• Stall prevention (current limit) function during deceleration (n55)

To prevent overvoltage during deceleration, the inverter automatically lengthen the deceleration time according to the value of main circuit DC voltage.

• Decreasing Motor Speed Fluctuation

Slip compensation

As the load becomes larger, rotor speed is reduced as motor slip increases. The slip compensating function regulates the motor shaft speed as the load increases by increasing the output frequency.

When inverter output current is equal to the motor rated current (n32), the compensation frequency is added to the output frequency.

Compensation frequency = Motor rated slip (n64)

Protection parameter selection

The electronic thermal overload function calculates motor temperature, based on inverter output current and time, to protect the motor from overheating. When the electronic thermal overload relay is enabled and excessive current is flowing to the motor, an “ ” error occurs, shutting OFF the inverter output and preventing excessive overheating in the motor. When operating with one inverter connected to one motor, an external thermal relay is not needed. When operating several motors with one inverter, install a thermal relay on each motor and disable the electronic overload protection (n33=2).

• General-purpose motor and inverter motor

Induction motors are classified as general-purpose motors (limited speed range) or inverter motors (wide speed range), based on their cooling capabilities. Therefore, the motor overload function operates differently between these two motor types.

(MEMOCON series) and MEMOBUS. In order to perform serial communications, RS-

485/422 interface card (optional) must be installed.

• MEMOBUS (MODBUS) communications

MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31

VS-mini units).

Transmission between master and slave (serial communication) is controlled according to the master program with the master initiating communication and the slave responding.

The master sends a signal to one slave at a time. Each slave has a pre-registered address No., and the master specifies the number and conducts signal communication. The slave receives the transmission to carry out designated functions and reply to the master.

Compliance

In order to conform to EMC standards, exclusive-use methods are required for line filter application, cable shielding and inverter installation. An outline of the methods follows.

The line filter and the inverter must be mounted on the same metal plate. The filter should be mounted as close to the inverter as practical. Keep cable as short as possible.

The metal plate should be securely grounded. The ground of the line filter and inverter must be bonded to the metal plate with as much area as possible.

For line power input cable, screened cable is recommended at least within the panel.

The screen of the cable should be connected to a solid ground. For the motor cable, screened cable (max. 20m) must be used and the screen of the motor cable is connected to ground at both ends by a short connection, using as large an area as practical.

For a more detailed explanation, please refer to Making YASKAWA Inverter Products

Safety Warnings and Operating Information for Inverters

Introduction

Depending on their protection rating configuration, parts of inverters can have live, uninsulated and hot surfaces during operation. If housing components, the control unit or terminal covers are removed, incorrect installation and operation can lead to serious injuries and damage to other installations. It is thus absolutely essential to observe all the warnings and instructions in the operating manual. Installation, setup and maintenance should only be performed by properly qualified staff. IEC 364 / Cenelec HD 384 or DIN VDE 0100 and IEC 664 or DIN VDE. The applicable national safety and accident prevention regulations must also be observed.) For the purpose of observance of the safety requirement qualified staff are defined as individuals who are familiar with the installation, setup and operation of the converters and who have the proper qualifications for this work.

Proper use for intended purpose

Inverters are designed for installation in electrical systems or machines. A converter installed in a machine may only be activated if the machine conforms to the provisions of EU directive 89/392/

EEC (machine directives). EN 60204 must also be observed. The converter may also only be operated if the requirements of the EMC directive (89/336/EEC) are also satisfied. This frequency converter conforms to the requirements of the low voltage directive, 73/23/EEC. The harmonized standards of the prEN 50178/DIN VDE 0160 series have been applied, in combination with EN 660439-1 / VDE

06600 Part 500 and EN 60146 / VDE 0558. The specifications on the ratings plate and the specifications and connection requirements described in the documentation must be observed at all times.

Transportation and storage

All instructions for transport, storage and proper handling must be observed. Climatic and environmental conditions must conform to the requirements of prEN 50178.

Installation

The converters must be installed and cooled in compliance with the regulations outlines and referred to in the documentation. The cooling air flow direction is an important requirement that must be observed. This means that the unit may only be installed and operated in the specified orientation (e.g. upright). All distances specified must also be observed. The converters must be protected against excessive stresses. No components may be bent and no distances required for proper insulation may be changed. To prevent the risk of static electricity damage never touch electronic components or contacts.

Electrical connections

All national safety regulations (e.g. VBG 4) must be observed when working on live equipment. The electrical installation of the units must conform to the applicable regulations. For further information please refer to the documentation. In particular, please take care to observe all installation instructions regarding proper EMC immunity, e.g. for shielding, earthing, location of filters and cable routing.

This also applies for equipment with CE approvals. Compliance with the EMC legislation limits is the responsibility of the machine or system manufacturer.

RCCBs

For information on the use of RCCBs with inverters please contact your supplier or Yaskawa representative.

Operation

In some systems it may be necessary to install additional monitoring and protective facilities to comply with the applicable safety and accident prevention regulations. The only changes permitted are to the operator software of the inverters. Please note that the capacitors can remain charged for up to around 5 minutes after the frequency converter has been disconnected from the power supply. You should thus always wait for a short period before opening the unit and touching the electrical connections.
