(factory setting)

Closed Loop Vector control

Fixed voltage/frequency ratio control

Fixed voltage/frequency ratio control with speed compensation using a PG

Current vector control without a PG

Closed Loop Vector control

Variable speed control, particularly control of multiple motors with one

Inverter and replacing existing inverters

Applications requiring high-precision speed control using a PG on the machine side

Variable speed control, applications requiring speed and torque accuracy.

Very high-performance control with a

PG (simple servo drives, high-precision speed control, torque control, and torque limiting)

Note With Open Loop or Closed Loop Vector control, the motor and Inverter must be connected 1:1. The motor capacity for which stable control is possible is 50% to 100% of the Inverters capacity.

V/f Control without PG (A1-02 = 0)

• Set either one a fixed V/f pattern (E1-03=0 to E) or specify a user-set V/f pattern (E1-03=F) as required for the motor and load characteristics using E1-04 to E1-13 in advanced programming mode.

Simple operation of a general-purpose motor at 50 Hz:

E1-03 = 0 or F (default)

If E1-03 = F, the default setting in the user setting from E1-04 to E1-13 are for 00 Hz

Simple operation of a general-purpose motor at 60 Hz:

E1-03 = 1

• Perform non-rotating autotuning for the line-to-line resistance if the motor cable is 50 m or longer for the

actual installation or if a heavy load causes motor stalling. Refer to the following section on Autotuning

for details on non-rotating autotuning.

V/f Control with PG (A1-02=1)

Additionally to the V/f control without PG settings the following settings have to be made:

• Set the number of motor poles in E2-04 (Number of Motor Poles)

• Set the number of pulses per rotation in F1-01 (PG Constant). If there is a reduction gear between the motor and PG, set the reduction ratio in F1-12 and F1-13 in advanced programming mode.

Open Loop Vector Control (A1-02 = 2)

Always perform autotuning. If the motor can be operated, perform rotating autotuning. If the motor cannot be operated, perform non-rotating autotuning. Refer to the following section on

Autotuning for details on auto-

tuning.

Closed Loop Vector Control (A1-02=3)

Always perform autotuning. If the motor can be operated, perform rotating autotuning. If the motor cannot be operated, perform non-rotating autotuning. Refer to the following section on

Autotuning for details on auto-

tuning.

Autotuning

Autotuning sets motor parameters automatically when using Open Loop or Closed Loop Vector control, when the cable length is long or the installation has changed.

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 is 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.

Non-rotating Autotuning (T1-01 = 1)

Non-rotating autotuning is 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 and V/f control with PG.

It can be used to improve the performance when the motor cable is long, the cable length has changed or when the motor and inverter have different capacities.

To perform autotuning in V/f control or V/f control with PG, 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 nonrotating 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.

• Autotuning an Inverter is fundamentally different from autotuning a servo system. Inverter autotuning automatically adjusts parameters according to detected motor data, whereas servo system autotuning adjusts parameters according to the detected size of the load.

•

When speed precision or torque precision is required at high speeds (i.e., 90% of the rated speed or higher), use a motor with a rated voltage that is ~20 V less than the input power supply voltage of the Inverter for

200 V-class Inverters and ~40 V less for 400 V-class Inverters. If the rated voltage of the motor is the same as the input power supply voltage, the voltage output from the Inverter will be unstable at high speeds and sufficient performance will not be possible.

Use non-rotating autotuning whenever the load cannot be disconnected from the motor.

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

If rotating autotuning is performed for a motor connected to a load, the motor data will not be found accurately and the might be poor. Never perform rotating autotuning for a motor 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 .

The status of the multi-function inputs and multi-function outputs during autotuning will be as shown in the following table.

Multi-function Outputs

Same as during normal operation

Maintain same status as when autotuning is started.

• 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 4.3

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

autotuning.

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.

After the completing 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 4.3 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.

* 3. Stable vector control will be possible when the setting is between 50% and 100%.

* 4. For an inverter motor or vector control motor, the voltage and frequency may be lower than for a general-purpose motor. Always confirm setting on the nameplate or in test reports. Also, if you know the no-load values, set the no-load voltage in T1-03 and the no-load frequency in T1-05 to obtain better accuracy.

* 5. The setting range is valid if Heavy Duty is selected (C6-01=0, default setting). If Normal Duty 1 or 2 is selected (C6-01=1 or 2) the setting range will be

Application Settings

Parameters can be set as required in advanced programming mode (i.e. “ADV” is displayed on the LCD screen). All the parameters which can be set in quick programming mode are also displayed and can be set in the advanced programming mode.

Setting Examples

•

The following points are examples of settings for applications.

When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor overheating protection.

To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.

To increase the speed of a 50 Hz motor by 10%, set E1-04 to 55.0 Hz.

To use a 0 to 10 V analog signal for a 50 Hz motor for variable-speed operation between 0 and 45 Hz (0% to 90% speed deduction), set H3-02 to 90.0%.

To limit the speed range between 20% and 80% set d2-01 to 80.0% and set d2-02 to 20.0%.

No-load Operation

This section describes trial operation in which the motor is in no-load state, that means the machine is not connected to the motor. To avoid failures caused by the wiring of the control circuit it is recommended to use the

LOCAL mode. Press the LOCAL/REMOTE key on the Digital Operator to change to LOCAL mode (the SEQ and REF indicators on the Digital Operator should be OFF).

Always confirm safety around the motor and machine before starting Inverter operation from the Digital

Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter. For applications, at which the machine can be driven in one direction only, check the motor rotation direction.

Operation with Jog frequency reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the JOG key on the Digital Operator. If the external control circuit prevents operation from the Digital Operator, confirm that emergency stop circuits and machine safety mechanisms are functioning, and then start operation in REMOTE mode (i.e., with a signal from the control signal terminal). The safety precautions must always be taken before starting the inverter and the motor connected.

NOTE

Both, a RUN command (forward or reverse) and a frequency reference (or multi-step speed command) must be provided to start Inverter operation.

Loaded Operation

Connecting the Load

•

After confirming that the motor has stopped completely, connect the mechanical system.

Be sure to tighten all the screws when connecting the motor shaft to the mechanical system.

412

Operation using the Digital Operator

•

Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.

If fault occurs during operation, make sure that the STOP key on the Digital Operator is accessible easily.

At first, set the frequency reference to a low speed, e.g. to one tenth of the normal operating speed.

Checking Operating Status

•

Having checked that the operating direction is correct and that the machine is operating smoothly at slow speed, increase the frequency reference.

After changing the frequency reference or the rotation direction, check that there is no oscillation or abnormal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too high.

Refer to Table 4.4

if hunting, vibration, or other problems originated by the control system occur.

Check and Recording Parameters

Use the verify mode (“VERIFY” is displayed on the LCD screen) to check parameters that have been changed for trial operation and record them in a parameter table.

Any parameters that have been changed by autotuning will also be displayed in the verify mode.

If required, the copy function in parameters o3-01 and o3-02 displayed in advanced programming mode can be used to copy the changed settings from the inverter to a recording area in the Digital Operator. If changed settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system recovery if for any reason the inverter has to be replaced.

The following functions can also be used to manage parameters.

• Saving user initial parameter values

•

Setting access levels for parameters

Setting a password

Saving User Initial Parameter Values (o2-03)

• If o2-03 is set to 1 after completing trial operation, the settings of parameters will be saved in a separate memory area in the inverter. When the Inverter settings have been changed for any reason, the parameters can be initialized to the settings saved in the separate memory area by setting A1-03 (Initialize) to 1110.

Parameter Access Levels (A1-01)

• A1-01 can be set to 0 (monitoring-only) to prevent parameters from being changed. A1-01 can also be set to 1 (User-specified Parameters) to display only parameters required by the machine or application in a programming mode. These parameters can be determined by setting the A2-XX parameters.

Password (A1-04 and A1-05)

• When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that parameters will be displayed only when the correct password has been input.

Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using Open

Loop Vector control.

If speeds are inaccurate during regeneration in Open Loop Vector control, enable Slip Compensation during regeneration (C3-04 = 1).

Use slip compensation to improve speed control during V/f control (A1-02 = 0).

Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-load Current (E2-03), and then adjust the Slip Compensation Gain (C3-01) between 0.5 and 1.5. The default setting for V/f control is

C3-01 = 0.0 (slip compensation disabled).

To improve speed response and stability in V/f control with a PG (A1-02 = 1), set the ASR parameters

(C5-01 to C5-05) to between 0.5 and 1.5 times the default value. (Normally it is not necessary to adjust this setting.)

Application

Sets the maximum torque and overload capability.

Used for heavy loads or large machine backlashes.

By adjusting the acceleration and deceleration times the torque is influenced indirectly.

Used to prevent shock at the acceleration/deceleration start and end.

Used to avoid continuous operation at possible machine resonance frequencies.

Used to prevent fluctuations in analog input signals caused by noise.

Used to prevent OV (overvoltage errors) and motor stalling for heavy loads or rapid acceleration/deceleration. Stall prevention is enabled by default and the setting normally has not to be changed. When using a braking resistor disable the stall prevention during deceleration by setting

L3-04 to 0 or set it to 3 (enabled with braking resistor).

Sets the maximum torque during Open Loop and Closed Loop Vector control. If a setting is reduced too much, stalling can occur under heavy loads.

Used to increase response for acceleration/deceleration or to reduce overshooting when there is low machine rigidity and the gain of the speed controller (ASR) cannot be increased. The inertia ratio between the load and motor and the acceleration time of the motor running unloaded must be set.

Speed Calculation:

When the search is started, the motor speed is calculated and acceleration/deceleration is performed from the calculated speed to the specified frequency

(motor direction is also searched).

Current Detection:

The speed search is started from the frequency when power was momentarily lost or the maximum frequency. The speed is detected by observing the current.

Speed search operating current

Adjust the strength of the zero-servo lock.

Enabled when the “zero-servo command” is set for a multifunction input. When the zeroservo command has been input and the frequency reference drops below DC Injection level (b2-01), a position control loop is created and the motor stops. Increasing the zero-servo gain increases the strength of the lock. Increasing it by much causes oscillations.

Sets the bandwidth of the Zero

3: Vector motor protection

When the Inverter power supply is turned off, the thermal value is reset, so even if this parameter is set to 1, protection may not be effective.

When several motors are connected to one Inverter, set to

L1-01 to 0 and ensure that each motor is installed with a protection device.

Sets the electric thermal detection time in seconds units.

Usually changing this setting is not necessary.

The factory setting is 150% overload for one minute.

When the motor's overload capability is known, also set the overload resistance protection time for when the motor is hot started.

Selects the operation when the input motor temperature (thermistor) input exceeds the alarm detection level (1.17 V) (H3-09 must be set to E).
