The Varispeed L7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance. Then wait for at least 5 minutes after all LEDs have gone out.

Do not perform a withstand voltage test on any part of the inverter. It contains semiconductors, which are not designed for such high voltages.

Do not remove the digital operator while the mains supply is switched on. The printed circuit board must also not be touched while the inverter is connected to the power.

Never connect general LC/RC interference suppression filters, capacitors or overvoltage protection devices to the inverter input or output.

To avoid unnecessary overcurrent faults, etc, being displayed, the signaling contacts of any contactor or switch fitted between inverter and motor must be integrated into the inverter control logic (eg baseblock).

This is absolutely imperative!

This manual must be read thoroughly before connecting and operating the inverter. All safety precautions and instructions for use must be followed.

The inverter must be operated with the appropriate line filters, following the installation instructions in this manual and with all covers closed and terminals covered.

Only then will adequate protection be provided. Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

Safety Precautions and Instructions for Use

1. General

Please read these safety precautions and instructions for use thoroughly before installing and operating this inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.

Live and hot inverter components may be accessible during operation. Removal of housing components, the digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installation or operation. The fact that frequency inverters control rotating mechanical machine components can give rise to other dangers.

The instructions in this manual must be followed. Installation, operation and maintenance may only be carried out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as individuals who are familiar with the installation, starting, operation and maintenance of frequency inverters and have the proper qualifications for this work. Safe operation of these units is only possible if they are used properly for their intended purpose.

The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power.

It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still carry dangerous voltages.

Children and other unauthorized persons must not be allowed access to these inverters.

Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with any form of access to the inverters.

2. Intended Use

Frequency inverters are intended for installation in electrical systems or machinery.

Their installation in machinery and systems must conform to the following product standards of the Low Voltage Directive:

EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices

EN 60204-1, 1997-12 Machine Safety and Equipping with Electrical Devices

Part 1: General Requirements (IEC 60204-1:1997)/

Please note: Includes Corrigendum of September 1998

EN 61010-1, A2, 1995 Safety Requirements for Information Technology Equipment

(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)

CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appropriate installation instructions.

3. Transportation and storage

The instructions for transportation, storage and proper handling must be followed in accordance with the technical data.

4. Installation

Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified direction. The inverter may therefore only be operated in the specified position (e.g. upright). Maintain the specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insulation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic components or contacts.

5. Electrical Connection

Carry out any work on live equipment in compliance with the national safety and accident prevention regulations. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding, grounding, filter arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of the manufacturer of the system or machine to ensure conformity with EMC limits.

Your supplier or OYMC representative must be contacted when using leakage current circuit breaker in conjunction with frequency inverters.

In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.

6. Notes

The Varispeed L7 frequency inverters are certified to CE, UL, and c-UL.

EMC Compatibility

1. Introduction

This manual was compiled to help system manufacturers using OYMC frequency inverters to design and install electrical switch gear. It also describes the measures necessary to comply with the EMC Directive. The manual's installation and wiring instructions must therefore be followed.

Our products are tested by authorized bodies using the standards listed below.

Product standard: EN 61800-3:1996

EN 61800-3; A11:2000

2. Measures to Ensure Conformity of OYMC Frequency inverters to the EMC Directive

OYMC frequency inverters do not necessarily have to be installed in a switch cabinet.

It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore has to be limited to general guidelines.

All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass this on to the environment like an aerial.

Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore allow HF or LF interference to get into the mains.

The basic countermeasures are isolation of the wiring of control and power components, proper grounding and shielding of cables.

A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding straps instead of cables is therefore definitely advisable.

Moreover, cable shields must be connected with purpose-made ground clips.

3. Laying Cables

Measures Against Line-Borne Interference:

Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as close to each other as possible, with cables kept as short as possible.

Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.

Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g.

metal plate).

Shielded Cable:

– Use a cable with braided shield.

– Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the cable to the ground plate with metal clips (see following figure).

Ground clip Ground plate

The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.

– Ground the cable shields at both ends.

– Ground the motor of the machine.

Observe the following precautions when mounting the Inverter.

•

Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a totally enclosed panel that is completely shielded from floating dust.

When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.

•

Do not install the Inverter on combustible material, such as wood.

Install the Inverter in a location free from radioactive materials and combustible materials.

Install the Inverter in a location free from harmful gasses and liquids.

Install the Inverter in a location without excessive oscillation.

Install the Inverter in a location free from chlorides.

Install the Inverter in a location not in direct sunlight.

Controlling the Ambient Temperature

To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme temperature increases. If the Inverter is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 45

°C.

Protecting the Inverter from Foreign Matter

Place a cover over the Inverter during installation to shield it from metal power produced by drilling.

Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be reduced, causing the Inverter to overheat.

Wiring Main Circuit Terminals

Installing a Moulded-case Circuit Breaker

When connecting the power input terminals (R/L1, S/L2, and T/L3) to the power supply using a moulded-case circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter.

•

Choose an MCCB with a capacity of 1.5 to 2 times of the inverter's rated current.

For the MCCB's time characteristics, be sure to consider the inverter's overload protection (one minute at

150% of the rated output current).

Installing an Earth Leakage Breaker

Inverter outputs use high-speed switching, so high-frequency leakage current is generated. If an earth leakage breaker should be used, select one that detects only the leakage current which is in the frequency range that is hazardous to humans but not high-frequency leakage currents.

•

For a special-purpose earth leakage breaker for Inverters, choose one with a sensitivity amperage of at least 30 mA per Inverter.

When using a general earth leakage breaker, choose one with a sensitivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

Installing a Magnetic Contactor at the Input

If the power supply for the main circuit is to be shut off by a control circuit, a magnetic contactor can be used.

The following things should be considered:

•

The Inverter 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.

Do not exceed one power up per hour.

When the Inverter is operated with the Digital Operator/Monitor, automatic operation cannot be performed after recovery from a power interruption.

Connecting Input Power Supply to the Terminal Block

Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence of input power supply is irrelevant to the output phase sequence.

Installing an Input AC Reactor

If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase advancing capacitor is switched, an excessive peak current may flow through the input power circuit, causing the inverter unit to break down.

To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals.

This also improves the power factor on the power supply side.

Installing a Surge Absorber

Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

-14

Wiring the Output Side of Main Circuit

Observe the following precautions when wiring the main output circuits.

Connecting the Inverter and Motor

Connect output terminals U/T1, V/T2, and W/T3 respective to the motor lead wires U, V, and W.

Check that the motor rotates forward with the forward run command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run command.

Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U/T1, V/T2, and W/T3. If voltage is applied to the output terminals, the internal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the Inverter case, an electric shock or grounding may occur. This is extremely hazardous. Do not short the output wires.

Do Not Use a Phase Advancing Capacitor

Never connect a phase advancing capacitor to an output circuit. The high-frequency components of the

Inverter output may overheat and be damaged and may cause other parts to burn.

Using a Magnetic Contactor

Check the control sequence to make sure, that the magnetic contactor (MC) between the Inverter and motor is not turned ON or OFF during inverter operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be created and the inverter’s overcurrent protection may operate.

Cable Length between Inverter and Motor

The cable between the Inverter and motor is 30 m max.

Ground Wiring

Observe the following precautions when wiring the ground line.

•

Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100

Ω and that of the 400 V Inverter with a ground resistance of less than 10

Ω.

•

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. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

When using more than one Inverter, be careful not to loop the ground wire.

Wire Sizes

For remote operation using analog signals, keep the control line length between the Analog Operator or operation signals and the Inverter to 30 m or less, and separate the lines from main power lines or other control circuits to reduce induction from peripheral devices.

When setting frequencies from an external frequency source (and not from a Digital Operator/Monitor), used shielded twisted-pair wires and ground the shield for the largest area of contact between shield and ground.

The terminal numbers and the appropriate wire sizes are shown in

•

Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,

W/T3, , 1, 2, and 3, PO, NO) and other high-power lines.

Separate wiring for control circuit terminals MA, MB, MC, M1, M2, M3, M4, M5, and M6 (contact outputs) from wiring to other control circuit terminals.

•

If using an optional external power supply, it shall be a UL Listed Class 2 power supply source.

Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.

Ground the cable shields with the maximum contact area of the shield and ground.

Cable shields have to be grounded on both cable ends.

Wiring Check

Checks

Check all wiring after wiring has been completed. Do not perform continuity check on control circuits. Perform the following checks on the wiring.

•

Is all wiring correct?

Have no wire clippings, screws, or other foreign material been left?

•

Are all screws tight?

Are any wire ends contacting other terminals?

Precautions

The wiring method is the same as the one used for straight solderless terminals. Refer to

page 2-17

. Observe

the following precautions when wiring.

•

Separate the control signal lines for the PG Speed Control Card from main power lines and other control circuits.

•

The shield must be connected to prevent operational errors caused by noise.

Connect the shield (green grounding cable of the option card) to the shield terminal (E).

•

Do not solder the ends of wires. Doing so may cause contact faults.

A separate power supply is required if the PG power supply consumption is higher than 200 mA. (If momentary power loss must be handled, use a backup capacitor or other method.)

Make sure not to exceed the PG cards maximum input frequency. The output frequency of the pulse generator can be calculated using the following formula.

PG (Hz) =

Motor speed at maximum output frequency (min

Verify Mode

The Verify mode is used to display any parameters that have been changed from their default settings in a programming mode or by autotuning. “None” will be displayed if no settings have been changed.

The parameter A1-02 is the only parameter from the A1- group, which will be displayed in the modified constant list if it has been changed before. The other parameters will not be displayed, even if they are different from the default setting.

In the verify mode, the same procedures can be used to change settings as they are used in the programming mode. Use the Increment, Decrement, and Shift/RESET keys to change a setting. When the DATA/ENTER key is pressed the parameter setting are written and the display returns to the Monitor display.

Autotuning Mode

Autotuning automatically measures and sets the required motor data in order to achieve the maximum performance. Always perform autotuning before starting operation when using the vector control modes.

When V/f control has been selected, stationary autotuning for line-to-line resistance can be selected only.

When the motor cannot be operated (e.g. if the ropes cannot be removed from the traction sheave), and Open

Loop or Closed Loop Vector Control shall be used, perform stationary autotuning.

Example of Operation for V/f control

The tuning method for V/f control is fixed to the measurement of the terminal resistance (T1-01=1). Input the the rated output power and the rated current specified on the nameplate of the motor and then press the RUN key. The motor data are measured automatically.

Always set the above items. Otherwise autotuning cannot be started, e.g. it cannot be started from the motor rated voltage input display.

A parameter can be changed from the setting displays using the Increment, Decrement, and Shift/RESET keys. The parameter will be saved when the DATA/ENTER key is pressed.

The following flowchart shows a V/f control Autotuning example.

Carrier Frequency Derating and

Current Limitation

Carrier Frequency Setting

The carrier frequency selection has a direct influence on the motor noise. The higher the carrier frequency the lower is the motor noise. On the other hand the overload capability of the inverter reduces with a higher carrier frequency. Both have to be considered when the setting is changed. Read the following for details.

Q Q Q

Carrier Frequency Selection

The factory setting is 8 kHz for units from 3.7 to 22 kW and 5 kHz for units from 30 to 55 kW. Usually the value has not to be changed. However, if it necessary to change it, observe the following precautions:

•

If speed and torque vary at low speeds: Lower the carrier frequency.

If Inverter noise is affecting peripheral devices: Lower the carrier frequency.

•

If leakage current from the Inverter too is large: Lower the carrier frequency.

If metallic noise from the motor is large: Increase the carrier frequency.

Carrier Frequency and Inverter Overload Capability

The inverter overload capability depends on the carrier frequency setting. The overload capability is 150% of the inverter rated current for 30 sec. After that an inverter overload fault (OL2) is shown.

If the carrier frequency is increased, a derating for the continuous output current like shown in

Fig 5.30

must be considered. The overload capability (OL2 Level) does not change. It will be 150% of the derated current for 30 sec.

RUN the normal brake sequence is used and the inverter accelerates to the inspection speed (d1-14).

To stop the inverter, the Inspection Run command or the Up/Down command must be removed. In this case:

•

The inverter output is cut by baseblock immediately

•

The brake open signal is removed immediately

The contactor control output is removed immediately

The falling edge of the inspection RUN command or UP/DOWN commands triggers the contactor open command, the motor brake close command and the base block.

Description

The inverter gets the direction signal (UP/DOWN)

The inverter gets the hardware base block disable signal (Not BB condition).

The inverter receives the speed reference signal.

The inverter sets the contactor closed signal.

The inverter waits for the contactor confirmation signal. If no digital input is set for “Contactor conformation signal”, the sequence is proceeded after exceeding the operation start delay time (S1-16).

Inverter will activate the output after passing the “RUN Delay Time” (S1-16).

DC Injection/zero servo or zero speed operation is started.

After passing the “Brake Open delay time” (S1-06), the inverter starts opening the brake.

The inverter keeps DC injection/zero servo or zero speed operation until

* the time S1-04 – S1-06 has exceeded if S1-06 < S1-04

* the time S1-06 has exceeded if S1-06 > S1-04 (try avoid this setting since the inverter could run against the brake)

The inverter starts to accelerate.

The inverter speed reaches the selected speed.

The speed is selection is changed to the leveling speed, the inverter starts to decelerate.

After reaching the leveling speed the inverter keeps operating at this speed.

The leveling signal is removed, the inverter ramps to stop.

The inverter reaches the zero speed.

The inverter starts DC injection/zero servo for the time set in S1-05.

After passing “Brake Close Delay Time” (S1-07), the inverter activates the brake close command.

The inverter continues DC Injection/zero speed or zero speed operation until S1-06 – S1-07 has time passed. Remove the direction signal.

The inverter shuts down the output voltage and the hardware base block signal must be set.

After the “Output contactor open delay time“(S1-19) has passed, the inverter releases the output contactor control signal.

Brake Sequence with torque compensation at start

This sequence works in Closed Loop Vector control only. To use the brake sequence with torque compensation at start,

•

the A1 function must be selected for “Torque compensation” (H3-15=1) or

•

one of the input channels Ch2 or Ch3 of the optional analog input card AI-14B must be set to “Torque

Remove the direction signal.

The inverter shuts down the output voltage and the hardware base block signal must be set.

After the “Output contactor open delay time” (S1-19), the inverter releases the output contactor control signal.

Torque compensation at start

If a load measuring device is installed in the elevator, in Closed Loop Vector mode an analog input can be used to give a torque compensation value to the inverter.

The adjusted torque compensation value is latched when the direction command is given. At start it is increased from zero to the latched value using the torque increase time set in parameter S1-22. The torque compensation value is kept during the whole ride and is cleared when the direction command is removed.

The torque compensation function can be adjusted using the parameters shown in the block diagram below.

Adjust the parameter so that the torque compensation value is zero when the elevator is balanced.

Principle

The short floor operation is activated when the leveling signal is set before the nominal speed was reached.

The inverter calculates the distance for deceleration from nominal speed to 0.4 x the nominal speed, which is equal to the area S in the figure below.

Speed speed

S eed x 0.4

speed t

There are two ways:

•

If the leveling speed is set when 40% of the nominal speed was reached already, the inverter keeps the reached speed until the distance equal to area S is reached. After that it decelerates to leveling speed.

•

If the leveling signal is set before 40% of the nominal speed was reached, the inverter accelerates to 40% of the nominal speed and keeps it until the distance is equal to area S is reached. After that it decelerates to leveling speed.

Acceleration and Deceleration Characteristics

Setting Acceleration and Deceleration Times

The acceleration time indicates the time to increase the speed from 0% to 100% of the maximum speed set in

E1-04. The deceleration time indicates the time to decrease the speed from 100% to 0% of E1-04.

Four separate acceleration and deceleration times can be set. It can be switched over between them

•

using digital input signals

•

using the automatic accel./decel. time switch over function with a changeable switching speed level

The display unit and the setting range for the times can be selected between 0.0 sec. or 0.00sec.

This function can be used to have a low acceleration at start. The parameter S1-26 must be set to a certain speed level (dwell speed) to activate the function.

When the inverter starts, the inverter accelerates to the S1-26 speed level using the acceleration time C1-07.

Once the motor speed exceeds the S1-26, the inverter will use the original acceleration time.

Stall Prevention During Acceleration

The Stall Prevention During Acceleration function prevents the motor from stalling if the load is too heavy.

If L3-01 is set to 1 (enabled) and the Inverter output current reaches 85% of the set value in L3-02, the acceleration rate will begin to slow down. When L3-02 is exceeded, the acceleration will stop.

If L3-01 is set to 2 (optimum adjustment), the motor accelerates so that the current is held at the level set in

L3-02. With this setting, the acceleration time setting is ignored.

Setting Precautions

•

Set the parameters as a percentage taking the inverter rated current to be 100%.

Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the inverter lifetime. Also do not disable the function.

If the motor stalls with the factory settings check the V/f pattern settings (E1-) and the motor setup

(E2-).

If the stall level has to be increased very much to get the elevator running, consider to use a one size bigger inverter.

Improving the Operation Performance

Reducing the Motor Speed Fluctuation (Slip Compensation Function)

When the load is large, the motor slip also grows and the motor speed decreases. The slip compensation function keeps the motor speed constant, regardless of changes in load. When the motor is operating at the rated load, parameter E2-02 (Motor Rated Slip)

× the slip compensation gain value in parameter C3-01 is added to the output frequency. The function can be used in V/f control or Open Loop Vector control.

Adjusting Slip Compensation Gain (C3-01)

The set value of C3-01 depends on the control method. The factory settings are:

•

Open Loop Vector control: 1.0

•

Closed Loop Vector control: 1.0

Set C3-01 to 1.0 to compensate the slip depending on the actual torque output status using the rated slip

(E2-02) as reference.

Adjust the slip compensation gain using the following procedure.

1. With Open Loop Vector control set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current). The motor rated slip can be calculated using the values on the motor nameplate and the following formula: slip (Hz) = –

120

The motor data can be set automatically using the autotuning function.

2. With V/f control set C3-01 to 1.0.

3. Apply a load and compare the speed reference and the actual motor speed during run with constant speed.

Adjust the slip compensation gain by 0.1 at a time. If the speed is less than the target value, increase the slip compensation gain, and if the speed is higher than the target value, reduce the slip compensation gain.

4. Setting C3-01 to 0.0 disables the slip compensation function.

Adjusting Slip Compensation Primary Delay Time Constant (C3-02)

The slip compensation delay time constant is set in ms. The setting value of C3-02 is 2000ms. Normally, there is no need to change these settings. When the slip compensation response is low, lower the set value. When the speed is unstable, increase the set value.

Improving the Operation Performance

Adjusting Slip Compensation Limit (C3-03)

Using parameter C3-03 the upper limit for the slip compensation can be set as a percentage, taking the motor rated slip as 100%.

If the speed is lower than the target value but does not change even after adjusting the slip compensation gain, the slip compensation limit may have been reached. Increase the limit, and check the speed again. Always make sure that the value of the slip compensation limit and reference frequency does not exceed the tolerance of the machine.

The following diagram shows the slip compensation limit for the constant torque range and fixed output range.

Selecting Slip Compensation Function During Regeneration (C3-04)

Enables or disables the slip compensation function during regeneration. The factory setting is enabled.

Operation Selection when Output Voltage Saturated (C3-05)

Generally the Inverter cannot output a voltage that is higher than the input voltage. If the output voltage reference for the motor (monitor parameter U1-06) exceeds the input voltage in the high-speed range, the output voltage becomes saturated, and inverter cannot respond to speed or load changes. This function automatically reduces the output voltage to avoid voltage saturation.

Thereby the speed control accuracy can be maintained even at high speeds (around the rated speed of the motor). By the lowered voltage the current can be around 10% higher compared to the operation without voltage limiter.

Torque Compensation Function Adjustments

The torque compensation function detects a rising motor load, and increases the output torque.

In V/f control the inverter calculates the motor primary loss voltage using the terminal resistance value (E2-

05) and adjusts the output voltage (V) to compensate insufficient torque at startup and during low-speed operation.

The compensation voltage is calculated by the calculated Motor primary voltage loss

× parameter C4-01.

In Open Loop Vector control the motor excitation current and the torque producing current are calculated and controlled separately. The torque compensation affects the torque producing current only.

The torque producing current is calculated by the calculated torque reference

Adjusting Torque Compensation Gain (C4-01)

Normally, there is no need to change this setting. If adjustments are necessary do the following:

Open Loop Vector control

•

If the torque response is slow increase the setting value.

•

If vibrations occur decrease the setting value.

V/f control

•

If the cable is very long, increase the set value.

•

If the motor capacity is smaller than the Inverter capacity (max. applicable motor capacity), increase the set value.

If the motor is vibrating, reduce the set value.

Setting precautions

•

Adjust this parameter so that the output current during low-speed rotation does not exceed the Inverter rated output current range.

•

Adjust the value in steps of 0.05 only.

Adjusting the Torque Compensation Delay Time Constant (C4-02)

The factory setting depends on the control mode. The factory settings are:

•

V/f control: 200 ms

•

Open loop vector control: 20 ms

Normally, there is no need to change this setting. If adjustments are necessary do the following:

•

If the motor is vibrating or if overshooting occurs, increase the set value.

•

If the torque response is slow, decrease the set value.

When this function is used, the following should be considered:

•

The compensation works for motoring operation only. It can not be used for regenerative operation.

If the starting torque compensation is used and a large shock is generated at the start, increase the starting torque compensation time constant (C4-05)

The function can be not be used unrestricted for elevators, since the load is not know before the start.

Adjusting ASR Proportional Gains (C5-01/03/09)

This gain adjusts the responsiveness of the speed control (ASR). The responsiveness of the ASR is increased when this setting is increased. Oscillation will occur if this setting is increased too much.

•

Increase C5-01 if the ASR is too slow at start or very low frequencies, decrease it if vibrations occur.

Increase C5-03 if the ASR is too slow at high speed or if overshooting occurs at speed changes in the high speed area, decrease it if vibrations occur

Increase C5-09 if ASR is slow in the low speed area or if undershooting occurs at leveling speed. If vibrations occur in the low speed area during deceleration decrease the value.

Adjusting ASR Integral Times (C5-02/04/10)

This parameter sets the speed control (ASR) integral time. Lengthening the integral time lowers the responsiveness and the speed accuracy when the load changes suddenly. Oscillation and overshooting can occur if this setting value is too low.

•

Decrease C5-02 if a speed deviation is compensated too slow at start or at very low frequencies, increase it if vibrations occur.

Decrease C5-04 if a speed deviation is compensated too slow at high speeds or if overshooting occurs at speed changes in the high speed area, increase it if vibrations occur.

Decrease C5-10 if a speed deviation is compensated too slow in the low speed area or if undershooting occurs at leveling speed. If vibrations occur in the low speed area during deceleration increase the value.

Motor acceleration time (n5-02)

The motor acceleration time n5-02 the time which is needed to accelerate the to the rated speed with the rated torque of the motor. The time can be estimated like follows:

•

Make the general setup (V/f pattern, Motor Setup, etc.)

Balance the elevator (car in middle position, Car weight = Counter weight)

•

Set the torque limits to 100% using the L7- parameters.

Set the acceleration time very short (the inverter must reach the torque limit very fast).

Start in any direction and measure the time from zero speed to top speed.

Set this time in n5-02.

Feed Forward Gain (n5-03)

This value usually has not to be changed.

•

Increase the time to improve the response to the speed reference

•

Improving the Leveling Accuracy by Slip compensation

This function can be used in V/f and Open Loop Vector control to compensate the motor slip influence at low speed under different load conditions. Thereby the leveling accuracy can be improved.

The inverter measures the current level or torque reference 1.0 sec after speed-agree condition (acceleration finished) for 0.5 sec and calculates the average value to estimate the load. This value is used for the calculation of slip which is added to the speed reference at leveling speed (see

Improving the Operation Performance

Adjustments

The Slip compensation values can be set separately for motoring and regenerative operation. Before adjusting this function the general setup should have been done (Motor Setup, V/f pattern, Speeds, ASR settings etc.).

To adjust the Slip compensation function do the following in motoring and regenerative mode:

•

Set the motor speed in S2-01 if V/f control is used.

Try to measure the actual motor speed during leveling.

•

If the motor speed is lower than the leveling speed reference increase S2-02 in motoring mode or decrease

S2-03 in regenerative mode.

If the motor speed is higher than the leveling speed reference decrease S2-02 in motoring mode or increase

S2-03 in regenerative mode.

Field Forcing

The field forcing function controls the motor flux and compensates the flux establishment delay of the motor.

Thereby it improves the motor responsiveness on changes in the speed reference or the load.

Field forcing is applied during all operation conditions except DC Injection.

Using parameter d6-06 a field forcing limit can be applied. A setting of 100% is equal to the no-load current set in parameter E2-03.

Protective Functions

Preventing Motor Stalling During Operation

Stall prevention during operation prevents the motor from stalling by automatically lowering the inverter output frequency when a transient overload occurs while the motor is operating at a constant speed.

Stall prevention during operation can be enabled in V/f control only. If the Inverter output current continues to exceed the setting in parameter L3-06 for 100 ms or longer, the motor speed is reduced. Enable or disable the stall prevention using parameter L3-05. Set the according deceleration times using C1-02 (Deceleration time

1) or C1-04 (Deceleration Time 2).

If the Inverter output current reaches the set value in L3-06 – 2%, the motor will accelerate again to the set frequency.

Precautions

If the motor capacity is smaller than the Inverter capacity or the motor stalls when operating at the factory settings, lower the stall prevention level during operation.

Setting Precautions

•

Set the parameters as a percentage taking the inverter rated current to be 100%.

Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the inverter lifetime. Also do not disable the function.

If the motor stalls with the factory settings check the V/f pattern (E1-) and the motor setup (E2-).

If the stall level has to be increased very much to get the elevator running check the mechanical system or consider to use a one size bigger inverter.

Motor Torque Detection / Car Stuck Detection

The inverter provides a torque detection function to detect overtorque (Car stuck) or undertorque. An alarm signal can be output to the digital output terminals M1-M2, M3-M4, or M5-M6.

To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection

NO/NC) in one of the parameter H2-01 to H2-03 (digital output terminals M1 to M6 function selection).

Overtorque/undertorque is detected by:

•

observing the output current in V/f control (the inverter rated output current is equal to 100%).

•

observing the torque reference value in Open Loop and Closed Loop Vector control (the motor rated torque is equal to 100%).

150% for 10 sec. The level can be adjusted in L6-02, the time in L6-03. The output is switched of and an OL3

Using a Digital Output to Signalize Operation at the Torque Limit

If a multifunction output is set for this function (H2-01 to H2-03 is set to “30”), the output is switched ON when the motor output torque reaches one of the torque limits.

Enabling Integral Torque Limit Operation (L7-06 and L7-07)

In Open Loop Vector control an integral operation can be applied to the torque limit function (P-control is standard). This improves the torque limit responsiveness and smoothes the torque limit operation. To enable the integral operation set parameter L7-07 to 1. The integral time constant can be set in parameter L7-06.

Setting Precautions

•

When the output torque reaches the torque limit, control and compensation of the motor speed is disabled to prevent the output torque from exceeding the torque limit. The torque limit has the priority.

The torque limit accuracy is ±5% at an output frequency of 10 Hz or above. When output frequency is lower than 10 Hz, the accuracy is lowered.

Setting Motor Rated Current (E2-01)

Setting Motor Overload Protection Characteristics (L1-01)

Set the overload protection function in L1-01 according to the used motor.

The induction motor's cooling abilities vary with the motor type. Consequently, you must select the electronic thermal protection characteristics.

Set L1-01 to:

0: to disable the thermal motor protection function.

1: to enable the thermal motor protection for a fan cooled general purpose motor (self-cooled).

2: to enable the thermal motor protection for an inverter motor (externally cooled).

3: to enable the thermal motor protection for a special vector motor (externally cooled).

Protective Functions

Setting Motor Protection Operation Time (L1-02)

The motor protection operation time is the time for that the motor can handle a 150% overload when it was running with the rated load before (i.e. operating temperature was reached before applying the 150% overload). Set the motor protection operation time in L1-02. The factory setting is 60 sec.

If the electronic thermal value reaches minimum

90% of the overload detection level, the output terminal that has been set will be turned ON.

Output Current Observation

The inverter can observe the output current and thereby detect if something is wrong in the sequence or with the motor connection. There are two observer functions, one for the start and one during run.

Inverter Protection

Inverter Overheat Protection

The Inverter is protected against overheating using a thermistor that detects the heatsink temperature.

When the overheat temperature level is reached the inverter output is switched off.

To prevent a suddenly and unexpected stop of the inverter due to an over temperature, an overheating prealarm can be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using parameter

L8-03 the inverter operation when an over temperature occurs can be selected.

If a multifunction output is programmed for this function the output is switched ON when the heatsink temperature exceeds the overheat pre-alarm level set in L8-02.

Blocking Inverter Outputs (Hardware Baseblock)

Using a baseblock command the inverter output can be cut immediately. When baseblock is activated the power supply of the IGBT driver circuit is cut off. In this case the motor will start coasting. If the baseblock command is cleared, the inverter output operation is resumed.

To use the baseblock function one of the digital input S8 must be used. The input is a NC input, i.e. if terminal

S8 is open, the inverter is baseblocked.

Stopping the Inverter on External Device Errors (External Error Function)

The external error function activates the error contact output and stops the Inverter operation. Using this function the inverter operation can be stopped on peripheral devices break down or other errors. The digital operator will display EFx (External error [input terminal Sx]). The x in EFx shows the number of the terminal at which the external error signal is input. For example, if an external error signal is input to terminal S3, EF3 will be displayed.

To use the external error function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selection).

Select the value to be set in H1-01 to H1-05 from a combination of any of the following three conditions.

Manual Setting of the Motor Parameters

Motor Rated Current Setting (E2-01)

Set E2-01 to the rated current value on the motor nameplate.

Motor Rated Slip Setting (E2-02)

Set E2-02 to the motor rated slip calculated from the number of rated rotations on the motor nameplate.

Rated speed (rpm) x No. of motor poles

Motor rated slip = Motor rated frequency (Hz) –

120

Motor No-Load Current Setting (E2-03)

Set E2-03 to the motor no-load current at the rated voltage and rated frequency. Normally, the motor no-load current is not written on the motor nameplate. Consult the motor manufacturer.

Factory setting is the no-load current value for a standard Yaskawa 4-pole motor.

Number of Motor Poles Setting (E2-04)

E2-04 is displayed only when Closed Loop Vector control method is selected. Set the number of motor poles as written on the motor nameplate.

Motor Line-to-Line Resistance Setting (E2-05)

E2-05 is set automatically when performing motor line-to-line resistance autotuning. When you cannot perform tuning, consult the motor manufacturer for the line-to-line resistance value. Calculate the resistance from

Motor and V/f Pattern Setup the line-to-line resistance value in the motor test report using the following formula, and then make the setting accordingly.

•

E-type insulation: [Line-to line resistance (

Ω) at 75°C of test report] × 0.92 (Ω)

B-type insulation: [Line-to line resistance (

Ω) at 75°C of test repor]t × 0.92 (Ω)

F-type insulation: [Line-to line resistance (

Ω) at 115°C of test report] × 0.87 (Ω)

Motor Leak Inductance Setting (E2-06)

Set the amount of voltage drop due to motor leakage inductance in E2-06 as percentage of the motor rated voltage. Make this setting when using high-speed motors because the standard value will be too high. (Normally, high speed motors have a low inductance compared to standard motors.) If the inductance is not written on the motor nameplate, consult the motor manufacturer.

Motor Iron Saturation Coefficients 1 and 2 Settings (E2-07)

E2-07 and E2-08 are set automatically during rotating autotuning.

Motor Iron Loss for Torque Compensation Setting (E2-08)

E2-10 is displayed only in V/f control method and can be set to increase the torque compensation accuracy.

The motor iron loss has to be set in kW.

Autotuning

Autotuning sets motor parameters automatically. Therefore some motor data which are usually written at the nameplate must be input and the autotuning has to be performed.

1. If the output contactors is controlled by the inverter it will be closed during autotuning. If the contactors are controlled by an external controller make sure to close the contacts during autotuning.

2. Make sure to close the baseblock contact during autotuning. Otherwise the autotuning can not be started and will terminate with a minor fault.

3. For rotating autotuning make sure to open the brake.

Setting the Autotuning Mode

One of the following three autotuning modes can be set.

•

Rotating autotuning

•

Non-rotating autotuning

Non-rotating autotuning for line-to-line resistance only

Rotating Autotuning (T1-01 = 0)

Rotating autotuning can be used for Open Loop and Closed Loop Vector control only. Set T1-01 to 0, input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The Inverter will operate the motor for approximately 1 minute and set the required motor parameters automatically.

Use this tuning mode only, if the motor can rotate freely which means that the ropes are removed.

The gearbox can be connected to the motor.

Non-rotating Autotuning (T1-01 = 1)

Non-rotating autotuning can be used for Open Loop and Closed Loop Vector control only. Set T1-01 to 1, input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The inverter will supply power to the non-rotating motor for approximately 1 minute and some of the motor parameters will be set automatically. The remaining motor parameters will be set automatically during the first time operation.

Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)

Non-rotating autotuning for line-to-line resistance can be used in any control mode. This is the only possible autotuning for V/f control.

To perform autotuning in V/f control, set T1-02 (Motor rated power) and T1-04 (Motor rated current) and then press the RUN key on the Digital Operator. The Inverter will supply power to the non-rotating motor for approximately 20 seconds and the Motor line-to-line resistance and cable resistance will be automatically measured.

Precautions Before Using Autotuning

Read the following precautions before using autotuning.

•

Use non-rotating autotuning whenever the load cannot be disconnected from the motor (e.g. the ropes can’t be removed).

Use rotating autotuning whenever performing autotuning when high precision is required or for a motor that is not connected to a load.

•

If the wiring between the Inverter and motor changes by 50 m or more perform non-rotating autotuning for line-to-line resistance.

If the motor cable is long (50 m or longer), perform non-rotating autotuning for line-to-line resistance.

If a mechanical brake is used, make sure that it is not opened for non-rotating autotuning. Make sure that it is opened for rotating autotuning.

Power will be supplied to the motor when non-rotating autotuning is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed

To cancel autotuning, press the STOP key on the Digital Operator.

Precautions for Rotating and Non-rotating Autotuning

If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown in

Fig 5.52

to prevent saturation of the Inverter’s output voltage. Use the following procedure to perform auto-

tuning:

1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).

2. Input the results of the following formula to T1-05 (Motor base frequency):

T1-05 = Base frequency from motor nameplate

Motor rated voltage

3. Perform autotuning.

Motor and V/f Pattern Setup

After the completion of autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s nameplate.

Output voltage

Rated voltage from motor name plate

T1-03

Base frequency from motor name plate x T1-03

Rated voltage from motor name plate

Output frequency

Base frequency from motor name plate

Fig 5.52 Motor Base Frequency and Inverter Input Voltage Setting

When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor rated voltage) to the input power supply voltage

× 0.9. In this case at high speeds the output current will increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current.

Precautions after Rotating and Non-rotating Autotuning

If the maximum output frequency and base frequency are different, set the maximum output frequency

(E1-04) after autotuning.

INFO

To set the V/f characteristics linear, set E1-07 and E1-09 to the same value. In this case, E1-08 will be ignored.

Setting Precautions

When the setting is to user-defined V/f pattern, beware of the following points:

•

When changing control method, parameters E1-07 to E1-10 will change to the factory settings for that control method.

Be sure to set the four frequencies as follows:

Monitor Selection (o1-01)

Using parameter o1-01 the third monitor item that is displayed in drive mode can be selected. This function has no effect on the optional LCD-operator (JVOP-160).

Monitor Display when the Power Supply is Turned ON (o1-02)

Using parameter o1-02 the monitor item (U1-) that is to be displayed on the Digital Operator/Monitor when the power supply is turned ON can be selected.

Changing Frequency Reference and Display Units (o1-03)

Set the Digital Operator/Monitor frequency reference and display units using parameter o1-03. The setting in o1-03 will affect the display units of the following monitor items:

•

U1-01 (Frequency Reference)

U1-02 (Output Frequency)

•

U1-05 (Motor Speed)

U1-20 (Output Frequency after Soft Start) d1-01 to d1-17 (Frequency references)

Changing the Units for Frequency Parameters Related to V/f settings (o1-04)

Using parameter o1-04 the unit for frequency parameters related to the V/f setting can be changed. If o1-04 is set to 0 it will be Hz. If o1-04 is set to 1 it will be rpm.

Changing the Display Contrast (o1-05)

Using o1-05 the contrast of the LCD display on the digital operator can be raised or lowered. Lowering the o1-

05 value will decrease the contrast and vice versa.

Enabling the LOCAL/REMOTE Key (o2-01)

Set o2-01 to 1 to enable the LOCAL/REMOTE Key on the Digital Operator.

If the key is enabled, frequency reference source or the RUN command source can be switched over between

LOCAL (Operator) and REMOTE (b1-01/02 setting).

Disabling the STOP Key (o2-02)

This parameter is used to set whether the STOP key on the operator is active during remote control (b1-02

≠ 0) or not.

If o2-02 is set to 1, a STOP command from the operators STOP key will be accepted. If o2-02 is set to 0 it will be disregarded.

Saving User Parameters (o2-03)

You can save the current Inverter parameter setting values as user-set parameter initial values. Therefore parameter o2-03 has to be set to 1.

To initialize the inverter parameters using the user-set initial values in memory set parameter A1-03 to 1110.

To clear the user-set initial values in memory, set o2-03 to 2.

Changing the Inverter Capacity Setting (o2-04)

The inverter capacity setting can be set using parameter o2-04. Refer to

page 4-53, Factory Settings that

Change with the Inverter Capacity (o2-04)

to see parameters that depend on this setting.

Normally it not necessary to change this setting, unless the control card has been changed.

Setting the Frequency Reference using the UP and DOWN Keys without Using the

Enter Key (o2-05)

This function is active when frequency references are input from the Digital Operator/Monitor. When o2-05 is set to 1, you can increment and decrement the frequency reference using the UP and DOWN keys without using the Enter key.

Operation Selection when the Digital Operator/Monitor is Disconnected (o2-06)

This function selects the operation when the digital operator gets disconnected when a RUN command is active.

If o2-06 is set to 0 the operation is continued.

If o2-06 is set to 1 the output is switched off and the motor coasts to stop. The fault contact is operated. When the operator is reconnected an OPR (Operator disconnected) is shown.

Cumulative Operation Time (o2-07 and o2-08)

The inverter has a function that counts the operation time of the inverter cumulatively.

Using parameter o2-07 the cumulative operation time can be changed, e.g. after a replacement of the control board. If parameter o2-08 is set to 0 the inverter counts the time whenever the power supply is switched ON. If o2-08 is set to 1 the time when a RUN command is active is counted only. The factory setting is 0.

Digital Operator/Monitor Functions

Cooling Fan Operation Time (o2-10)

This function counts the operating time of the inverter mounted fan cumulatively.

Using parameter o2-10 the counter can be reset, e.g. when the fan was replaced.

Fault Trace Initialize (o2-12)

This function can be used to initialize the fault trace by setting parameter o2-12 to 1.

“Number of Travels” counter Initialize (o2-15)

Using this parameter the lift operation counter monitor (U1-55) can be initialized.

Copying Parameters (JVOP-160 only)

The Digital Operator/Monitor can perform the following three functions using a built-in EEPROM (non-volatile memory).

•

Store Inverter parameter set values in the Digital Operator/Monitor by setting o3-01 to 1 (READ)

•

Write parameter set values stored in the Digital Operator/Monitor to the Inverter by setting o3-01 to 2

(COPY)

Compare parameter set values stored in the Digital Operator/Monitor with Inverter parameters settings by setting o3-01 to 3 (VERIFY)

The data saved in the operator can be protected from overwriting by setting parameter o3-02 to 0. In the case a

READ command can not be executed. If it is nevertheless still done, “PrE” will be displayed at the operator.

If A1-01 is set to 0, all parameters except A1-01 and A1-04 are write protected, U1-, U2- and U3-

will be displayed. If A1-01 is set to 1, only the parameters A1-01, A1-04 and A2- can be read or written, U1-, U2- and U3- will be displayed. All other parameters will not be displayed.

If you set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selection) to 1B

(write parameters permitted), parameters can be written from the digital operator when the terminal that has been set is ON. When the set terminal is OFF, writing parameters other than the frequency reference is prohibited. However, the parameters can be read.

Using PG Speed Control Card

There are two types of PG Speed Control Card that can be used in Closed Loop Vector control:

•

PG-B2: A/B-phase pulse input, compatible with complimentary outputs.

•

PG-X2: A/B/Z-phase pulse input, compatible with line drivers (RS-422).

For the mounting instructions, specifications and connection diagrams refer to

page 2-24, Installing and Wiring Option Cards

If Open Loop Vector control is used and a PG card is installed, the speed detected by the PG card is displayed in the monitor parameter U1-05. Therefore the PG constant has to be set in parameter F1-01. The direction of the speed detection can be changed by parameter F1-05.

To change the U1-05 value to the internally calculated value remove the PG card.

IMPORTANT

Setting Number of PG Pulses (F1-01)

Set the number of PG (Pulse Generator/Encoder) pulses in pulses per revolution.

Suit the PG Rotation Direction and Motor Rotation Direction (F1-05)

Parameter F1-05 suits the PG rotation direction to the motor rotation direction. If the motor is rotating forwards, set whether it is A-phase leads or B-phase leads.

With the used PG the A-phase leads (CCW) when motor rotation is forward.

Generally, the A-phase leads when the rotation direction is counter-clockwise (CCW) seen from the shaft side

(FWD command is input).

Setting PG Pulse Monitor Output Division Ratio (F1-06)

This function is enabled only when using PG speed control card PG-B2. Set the division ratio for the PG pulse monitor output. The set value is expressed as n for the higher place digit, and m for the two lower place digits.

The dividing ratio is calculated as follows:

Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32

F1-06 =

The division ratio can be set within the following range: 1/32

≤ F1-06 ≤ 1. For example, if the division ratio is

1/2 (set value 2), half of the number of pulses from the PG are output at the pulse monitor.

Detecting PG Open Circuit (F1-02 and F1-14)

Parameter F1-02 selects the stopping method when a PG disconnection is detected.

PG open (PGO) is only detected when the inverter is running at least with a frequency reference higher than

1% of the maximum output frequency or above the minimum frequency (E1-09) and the PG feedback signal is missing for the time set in F1-14 or longer.

Detecting Motor Overspeed (F1-03, F1-08 and F1-09)

An overspeed (OS) is detected when the motor speed continues to exceed the set frequency value in F1-08 for a time longer than set in F1-09. After detecting an overspeed (OS), the Inverter stops according to the setting in F1-03.

PG Option Cards

Detecting Speed Difference between the Motor and Speed Reference (F1-04, F1-10 and F1-11)

Speed deviation is detected when the speed deviation (i.e., the difference between the speed reference and the actual motor speed) is too large. Speed deviation (DEV) is detected only after a speed agreement (speed reference and actual motor speed are within the setting range of L4-02) and if a speed deviation higher than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the Inverter stops according to the setting in F1-04.

Protective and Diagnostic Functions

This section describes the fault and alarm functions of the Inverter. These functions include fault detection, alarm detection, operator programming error detection and auto-tuning error detection.

Fault Detection

When the Inverter detects a fault, the fault contact output operates and the Inverter output is switched OFF causing the motor to coast to stop. (The stopping method can be selected for some faults.) A fault code is displayed on the Digital Operator/Monitor.

The faults can be categorized in two groups:

•

Faults that can be rested using an input or the reset key at the Digital Operator without cycling the power

(resetable faults)

Faults that require to cycle the power (non-resetable faults)

When a fault has occurred refer to the following identify the fault and to correct the causes.

To reset a fault it is necessary to remove the fault and the RUN signal. Only then a Reset signal is accepted.

See the following tables for the faults and corrective actions.

Troubleshooting

Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started. If that occurs, use this section as a reference and perform the appropriate countermeasures.

If the contents of the fault are displayed, refer to

page 6-2, Protective and Diagnostic Functions

If A Parameter Cannot Be Set

Use the following information if a parameter cannot be set.

The display does not change when the Increment and Decrement keys are pressed.

The following causes are possible:

The Inverter is operating (drive mode).

There are some parameters that cannot be set during operation. Turn off the RUN command and then set the parameters

Passwords do not match. (Only when a password is set.)

If the parameter A1-04 (Password) and A1-05 (Password Setting) settings are different, the parameters for the initialize mode cannot be changed. Enter the correct password in A1-04.

If you cannot remember the password, display A1-05 (Password Setting) by pressing the Shift/RESET key and the MENU key simultaneously while in the A1-04 display. Then set the password and input the set password in parameter A1-04.

OPE01 through OPE11 is displayed.

The set value for the parameter is wrong. Refer to

Table 6.23

in this chapter and correct the settings.

CPF00 or CPF01 is displayed.

This is a Digital Operator/Monitor communication error. The connection between the Digital Operator/Monitor and the Inverter may be faulty. Remove the Digital Operator/Monitor and then re-install it.

If the Motor Does Not Operate Properly

The following causes are possible:

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

The frequency reference is 0.00 Hz or a no speed is selected by the digital inputs. Check the input signals and the frequency reference settings.

Also make sure to set the Baseblock signal. The inverter does not accept any input if it is base blocked.

The load is too heavy

Check the motor current. If it is at the limit of the inverter rated current the load might be too high. Check the inverter size and the mechanical system. Check also if the brake is operating or not.

If the Direction of the Motor Rotation is Reversed

If the motor rotates in the wrong direction, the motor output wiring may be incorrect. When the Inverter operates in the forward direction, the forward direction of the motor will depend on the manufacturer and the motor type, so be sure to check the motor specification

The direction of the motor rotation can be reversed by switching two wires among U, V, and W. If using an encoder, the polarity will also have to be switched. If the Inverter is operated in V/f mode also parameter b1-

04 can be used to change the rotation direction.

If the Motor Stalls or Acceleration is Slow

The torque limit has been reached.

When a torque limit has been set in parameters L7-01 to L7-04, the output torque will be limited according these settings. Therefore the motor may not develop enough torque to accelerate or the acceleration time might be very long.

The stall prevention level during acceleration is too low.

If the value set for L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be increased. Check that the set value is suitable and that the load is not too large for the motor.

The stall prevention level during running is too low.

If the value set for L3-06 (Stall Prevention Level during Running) is too low, the motor speed and torque will be limited. Check that the set value is suitable and that the load is not too large for the motor.

Auto-tuning has not been performed for vector control

Vector control will not work properly if auto-tuning has not been performed. Perform auto-tuning, or set the motor parameters through calculations.

Troubleshooting

If Motor Deceleration is Slow

The following causes are possible:

The deceleration time is too long

The following causes are possible:

The deceleration time setting is too long.

Check the deceleration time setting (parameters C1-02, C1-04, C1-06, and C1-08).

Motor torque is insufficient.

If the parameters are correct and there is no overvoltage fault, then the motor's power may be insufficient.

Consider increasing the motor and Inverter capacity.

The torque limit has been reached.

When a torque limit is reached (L7-01 to L7-04), the motor torque will be limited. This can cause the deceleration time to be extended. Check to be sure that the value set for the torque limit is suitable.

If the Motor Overheats

The following causes are possible:

The load is too large.

If the motor load is too large and the torque exceeds the motor’s rated torque, the motor may overheat. Reduce the loads by either reducing the load or increasing the acceleration/deceleration times. Also consider increasing the motor size.

The ambient temperature is too high.

The motor rating is determined by a particular ambient operating temperature range. The motor will overheat if it is run continuously at the rated torque in an environment where the maximum ambient operating temperature is exceeded. Lower the motor's ambient temperature to be within its acceptable range.

Auto-tuning has not been performed for vector control

Vector control may not perform efficiently if auto-tuning has not been performed. Perform auto-tuning, or set the motor parameters through hand calculations. Alternatively, change the Control Mode Selection (A1-02) to

V/f Control (0 or 1).

If Peripheral Devices are Influenced by the Starting or Running Inverter

The following solutions are possible:

•

Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. This will help to reduce the amount of transistor switching noise.

•

Install an Input Noise Filter at the Inverter's input power terminals.

Install an Output Noise Filter at the Inverter's motor terminals.

Use shielded motor cables or a conduit. Metal shields electrical noise.

Check the grounding of the Inverter and motor.

Separate main circuit wiring from control circuit wiring.

If the Earth Leakage Breaker Operates When the Inverter is Running

The Inverter’s output is pulse modulated, i.e. the output voltage consists of high frequency pulses (PWM).

This high frequency signal causes a certain amount of leakage current which may cause the earth leakage breaker to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or higher, with an operating time of 0.1 s or more), or one that incorporates high frequencies countermeasures (i.e., one designed for use with Inverters). It will also help to some extent to lower the Inverter's Carrier Frequency Selection (C6-02). In addition, remember that the leakage current increases as the cable is lengthened.

Troubleshooting

If There is Mechanical Oscillation

Use the following information when there is mechanical vibration:

Oscillation and hunting occur with V/f control

The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01

(Torque Compensation Gain) and C4-02 (Torque Compensation Delay Time). Decrease C4-01 carefully in steps of 0.05 and/or increase C4-02.

Furthermore the Slip Compensation Delay Time (C3-02) can be decreased.

Oscillation and hunting occur with Open Loop Vector control.

The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01

(Torque Compensation Gain), C4-02 (Torque Compensation Delay Time Parameter) and C3-02 (Slip Compensation Delay Time) in order. Lower the gain parameters and raise the delay time parameters.

If auto-tuning has not been performed, proper performance may not be achieved for Vector Control. Perform auto-tuning or set the motor parameters through hand calculations.

Oscillation and hunting occur with Closed Loop Vector control

The gain adjustment may be insufficient. Adjust the speed control loop (Automatic Speed Regulator, ASR) by changing C5- gain parameters. If the oscillation points overlap with those of the machine and cannot be eliminated, increase the ASR Delay Time, and then readjust the ASR gains.

If auto-tuning has not been performed, proper performance may not be achieved for Closed Loop Vector Control. Perform auto-tuning or set the motor parameters through hand calculations.

Check the following items during periodic maintenance.

•

The motor should not vibrate or make unusual noises.

•

There should be no abnormal heat generation from the Inverter or motor.

The ambient temperature should be within the Inverter’s specifications.

•

The output current value shown in U1-03 should not be higher than the motor or the Inverter rated current for extended period of time.

The cooling fan in the Inverter should be operating normally.

Before attempting any maintenance checks, make sure that the three-phase power is disconnected. With power removed from the unit, the DC bus capacitors will stay charged for several minutes. The Charge LED in the

Inverter will glow red until the DC bus voltage is below 10VDC. To ensure that the DC bus is completely discharged, measure between the positive and negative bus with a DC voltmeter set to the highest scale. Be sure not to touch terminals immediately after the power has been turned off. Doing so can result in electric shock.

Inverter Application Precautions

Selection

Observe the following precautions when selecting an Inverter.

Installing Reactors

A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a compensating capacitor. Excessive peak current can destroy the converter section. To prevent this, install a DC or AC reactor to improve the power supply power factor.

If a thyristor convertor, such as a DC drive, is connected in the same power supply system, connect a DC or

AC reactor regardless of the power supply conditions shown in the following diagram.

Fig 9.4

Installation

Observe the following precautions when installing an Inverter.

Installation in Enclosures

Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter on wood or other combustible materials.

Installation Direction

Mount the Inverter vertically to a wall or other vertical surface.

Settings

Observe the following precautions when making settings for an Inverter.

Upper Limits

The maximum output frequency can be set up to 120Hz. Setting the output frequency too high can damage the machine. So pay attention to the mechanical system and observe required limits for the output frequency.

Inverter Application Precautions

DC Injection Braking

If the DC Injection Braking Current or the Braking Time are set too high the motor can overheat what can damage the motor

Acceleration/Deceleration Times

The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load torque, and the load's inertial moment (GD

/4). If the stall prevention functions are activated during acceleration or deceleration, it might be necessary to increase the acceleration or deceleration time.

To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.

Handling

Observe the following precautions when wiring or performing maintenance for an Inverter.

Wiring Check

The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.

Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully.

Magnetic Contactor Installation

If a magnetic contactor is installed in the power supply line do not exceed one start per hour. Switching more often can damage the inrush current prevention circuit.

Maintenance and Inspections

After turning OFF the main circuit power supply it can take several minutes before the DC bus is discharged completely. The CHARGE LED, indicating if the DC bus is charged, glows above a voltage of 10VD.

Motor Application Precautions

Using the Inverter for an Existing Standard Motor

Observe the following precautions when using an Inverter for an existing standard motor.

Low Speed Ranges

If a standard cooled motor is used at low speed the cooling effects are diminished. If the motor is used in constant torque applications in low speed area the motor may overheat. If full torque is required at low speed continuously an externally cooled motor must be used.

Installation Withstand Voltage

If the inverter is used with an input voltage of 440 V or higher and long motor cables, voltage spikes at the motor terminals may occur which can damage the motor windings. Please ensure that the motor insulation class is sufficient.

Noise

The noise generated in the motor depends on the carrier frequency. The higher the setting the less the generated noise is.

Using the Inverter for Special Motors

Observe the following precautions when using a special motor.

Pole-changing Motor

The rated input current of pole-changing motors differs from that of standard motors. Select an appropriate

Inverter according to the maximum current of the motor.

Single-phase Motor

Do not use an Inverter for a single-phase capacitor motor. Any capacitors directly connected to the inverter output may damage the Inverter.

User Constants

Factory settings are given in the following table. These are factory settings for a 200 V Class Inverter with

3.7 kW (open loop vector control).
