Chapter 1 Introduction|

RFI Jumper

RFI Jumper: The AC motor drive may emit the electrical noise. The RFI jumper is used to suppress

the interference (Radio Frequency Interference) on the power line.

Main power isolated from earth:

If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off.

Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage

(according to IEC 61800-3) and reduce earth leakage current.

CAUTION!

1. After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore,

please make sure that main power has been switched off before cutting the RFI jumper.

2. The gap discharge may occur when the transient voltage is higher than 1,000V. Besides,

electro-magnetic compatibility of the AC motor drives will be lower after cutting the RFI

jumper.

3. Do NOT cut the RFI jumper when main power is connected to earth.

4. The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and

motor must be separated if high voltage test is performed and the leakage currents are

too high.

5. To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC

motor drive is installed on an ungrounded power system or a high resistance-grounded

(over 30 ohms) power system or a corner grounded TN system.

CAUTION!

1. The wiring of main circuit and control circuit should be separated to prevent erroneous actions.

2. Please use shield wire for the control wiring and not to expose the peeled-off net in front of the

terminal.

3. Please use the shield wire or tube for the power wiring and ground the two ends of the shield

wire or tube.

4. Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it

comes in contact with high voltage.

5. The AC motor drive, motor and wiring may cause interference. To prevent the equipment

damage, please take care of the erroneous actions of the surrounding sensors and the

equipment.

6. When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals

U/T1, V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation,

switch over any of the two motor leads.

7. With long motor cables, high capacitive switching current peaks can cause over-current, high

leakage current or lower current readout accuracy. To prevent this, the motor cable should be

less than 20m for 3.7kW models and below. And the cable should be less than 50m for 5.5kW

models and above. For longer motor cables use an AC output reactor.

8. The AC motor drive, electric welding machine and the greater horsepower motor should be

grounded separately.

9. Use ground leads that comply with local regulations and keep them as short as possible.

10. No brake resistor is built in the VFD-EL series, it can install brake resistor for those occasions

that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11. Multiple VFD-EL units can be installed in one location. All the units should be grounded directly

to a common ground terminal, as shown in the figure below. Ensure there are no ground

loops.

Speed Search

Applications Purpose Functions

Windmill, winding machine, fan and all inertia loads

Restart freerunning motor

Before the free-running motor is completely stopped, it can be restarted without detection of motor speed. The AC motor drive will auto search motor speed and will accelerate when its speed is the same as the motor speed.

DC Brake before Running

Applications Purpose Functions

When e.g. windmills, fans and pumps rotate freely by wind or flow

Keep the freerunning motor at standstill.

If the running direction of the freerunning motor is not steady, please execute DC brake before start-up.

without applying power

Energy Saving

Applications Purpose Functions

Punching machines fans, pumps and precision machinery

Energy saving and less vibrations

Energy saving when the AC motor drive runs at constant speed, yet full power acceleration and deceleration For precision machinery it also helps to lower vibrations.

Revision August 2008, 2ELE, V1.02 4-31

Chapter 4 Parameters|

 This parameter sets the Mid-Point Voltage of any V/f curve. With this setting, the V/f ratio

between Minimum Frequency and Mid-Point Frequency can be determined. This parameter

must be equal to or greater than Minimum Output Voltage (Pr.01.06) and equal to or less than

Maximum Output Voltage (Pr.01.02).

01.05 Minimum Output Frequency (Fmin) Unit: 0.01

Settings 0.10 to 600.0Hz Factory Setting: 1.50

 This parameter sets the Minimum Output Frequency of the AC motor drive. This parameter

must be equal to or less than Mid-Point Frequency (Pr.01.03).

01.06 Minimum Output Voltage (Vmin) Unit: 0.1

Settings 115V/230V series 0.1 to 255.0V Factory Setting: 10.0

Output Frequency Lower Limit

Unit: 0.1

Settings 0.0 to 100.0% Factory Setting: 0.0

 The Upper/Lower Limits are to prevent operation errors and machine damage.

 If the Output Frequency Upper Limit is 50Hz and the Maximum Output Frequency is 60Hz, the

Output Frequency will be limited to 50Hz.

 If the Output Frequency Lower Limit is 10Hz, and the Minimum Output Frequency (Pr.01.05) is

set to 1.0Hz, then any Command Frequency between 1.0-10Hz will generate a 10Hz output

from the drive. If the command frequency is less than 1.0Hz, drive will be in ready status

without output.

 This parameter must be equal to or less than the Output Frequency Upper Limit (Pr.01.07).

 The Output Frequency Lower Limit value = (Pr.01.00 * Pr.01.08) /100.

01.19 Accel/Decel Time Unit

Factory Setting: 0

Settings 0 Unit: 0.1 sec

1 Unit: 0.01 sec

 The Acceleration Time is used to determine the time required for the AC motor drive to ramp

from 0 Hz to Maximum Output Frequency (Pr.01.00). The rate is linear unless S-Curve is

“Enabled”; see Pr.01.17.

 The Deceleration Time is used to determine the time required for the AC motor drive to

decelerate from the Maximum Output Frequency (Pr.01.00) down to 0 Hz. The rate is linear

unless S-Curve is “Enabled.”, see Pr.01.18.

 The Acceleration/Deceleration Time 1, 2, 3, 4 are selected according to the Multi-function Input

Terminals Settings. See Pr.04.05 to Pr.04.08 for more details.

Revision August 2008, 2ELE, V1.02 4-33

Chapter 4 Parameters|

 In the diagram shown below, the Acceleration/Deceleration Time of the AC motor drive is the

time between 0 Hz to Maximum Output Frequency (Pr.01.00). Suppose the Maximum Output

Frequency is 60 Hz, Minimum Output Frequency (Pr.01.05) is 1.0 Hz, and

Acceleration/Deceleration Time is 10 seconds. The actual time for the AC motor drive to

accelerate from start-up to 60 Hz and to decelerate from 60Hz to 1.0Hz is in this case 9.83

seconds. ((60-1) * 10/60=9.83secs).

 Only external terminal JOG (MI3 to MI12) can be used. When the Jog command is “ON”, the

AC motor drive will accelerate from Minimum Output Frequency (Pr.01.05) to Jog Frequency

(Pr.01.15). When the Jog command is “OFF”, the AC motor drive will decelerate from Jog

Frequency to zero. The used Accel/Decel time is set by the Jog Accel/Decel time (Pr.01.13,

Pr.01.14).

4-34 Revision August 2008, 2ELE, V1.02

1 Auto acceleration, linear Deceleration.

2 Linear acceleration, auto Deceleration.

3 Auto acceleration / deceleration (set by load)

4 Auto acceleration / deceleration (set by Accel/Decel Time setting)

 With Auto acceleration / deceleration it is possible to reduce vibration and shocks during

starting/stopping the load.

During Auto acceleration the torque is automatically measured and the drive will accelerate to

the set frequency with the fastest acceleration time and the smoothest starting current.

During Auto deceleration, regenerative energy is measured and the motor is smoothly stopped

with the fastest deceleration time.

But when this parameter is set to 4, the actual accel/decel time will be equal to or more than

parameter Pr.01.09 ~Pr.01.12.

 Auto acceleration/deceleration makes the complicated processes of tuning unnecessary. It

makes operation efficient and saves energy by acceleration without stall and deceleration

without brake resistor.

 In applications with brake resistor or brake unit, Auto deceleration shall not be used.

0.1 to 10.0/0.01 to 10.00 S-curve enabled (10.0/10.00 is the smoothest)

 This parameter is used to ensure smooth acceleration and deceleration via S-curve.

The S-curve is disabled when set to 0.0 and enabled when set to 0.1 to 10.0/0.01 to 10.00.

Setting 0.1/0.01 gives the quickest and setting 10.0/10.00 the longest and smoothest S-curve.

The AC motor drive will not follow the Accel/Decel Times in Pr.01.09 to Pr.01.12.

 The diagram below shows that the original setting of the Accel/Decel Time is only for reference

when the S-curve is enabled. The actual Accel/Decel Time depends on the selected S-curve

(0.1 to 10.0).

1 STOP: coast to stop E.F.: coast to stop

2 STOP: ramp to stop E.F.: ramp to stop

3 STOP: coast to stop E.F.: ramp to stop

 The parameter determines how the motor is stopped when the AC motor drive receives a valid

stop command or detects External Fault.

Ramp: the AC motor drive decelerates to Minimum Output Frequency (Pr.01.05)

according to the deceleration time and then stops.

Coast: the AC motor drive stops the output instantly upon command, and the motor

free runs until it comes to a complete standstill.

The motor stop method is usually determined by the characteristics of the motor load and

how frequently it is stopped.

(1) It is recommended to use “ramp to stop” for safety of personnel or to prevent

material from being wasted in applications where the motor has to stop after the

drive is stopped. The deceleration time has to be set accordingly.

(2) If motor free running is allowed or the load inertia is large, it is recommended to

select “coast to stop”. For example: blowers, punching machines, centrifuges

and pumps.

Signifi cant

 From the table, we see that the PWM carrier frequency has a significant influence on the

electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise.

 The PWM carrier frequency will be decreased automatically by the ambient temperature and

output current of the AC motor drives. It is used to prevent AC motor drive overheat and

extend IGBT’s life. Therefore, it is necessary to have this kind of protection method. Take an

example of 460V models, assume that the carrier frequency is 12kHz, ambient temperature is

50 degrees C with single AC motor drive. If the output current exceeds 80% * rated current,

the AC motor drive will decrease the carrier frequency automatically by the following chart. If

output current is around 100% * rated current, the carrier frequency will decrease from 12k Hz

to 8k Hz.

 Use this parameter to change frequency when (1) Pr.00.13 is not set to 0 and frequency

source is from communication or (2) Pr.02.10 is not set to 0.

02.19 User-defined Value 2 Unit: 1

Settings Read-only Factory Setting: 0

 For example: suppose that the frequency source is the first master frequency + second master

frequency command (first master frequency is from keypad and second master frequency is

from AVI), user-defined value 1 is set to 180.0(Pr.00.13 is set to 1800, Pr.00.14 is set to 1).

AVI=2V=180.0/(2V/10V)=36.0, frequency is 36.0/(180.0/60.0)=12.0Hz

Pr.02.18=30.0, frequency is 30.0/(60.0/180.0)=10.0Hz

At this moment, the keypad will display 66.0(36.0+30.0) and the output frequency is

22.0Hz(12.0+10.0). When reading the value from communication address, the value will be

shown as follows: 2102H and 2103H are 22.0Hz, 0212H(Pr.02.18) is 30.0, 0213H(Pr.02.19) is

Analog Output Signal (AFM)

Factory Setting: 0

Settings 0 Analog Frequency Meter (0 to Maximum Output Frequency)

 This parameter sets the function of the AFM output 0~+10VDC (ACM is common).

03.04 Analog Output Gain Unit: 1

Settings 1 to 200% Factory Setting: 100

 This parameter sets the voltage range of the analog output signal AFM.

 When Pr.03.03 is set to 0, the analog output voltage is directly proportional to the output

frequency of the AC motor drive. With Pr.03.04 set to 100%, the Maximum Output Frequency

(Pr.01.00) of the AC motor drive corresponds to +10VDC on the AFM output.

 Similarly, if Pr.03.03 is set to 1, the analog output voltage is directly proportional to the output

current of the AC drive. With Pr.03.04 set to 100%, then 2.5 times the rated current

corresponds to +10VDC on the AFM output.

NOTE

Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10V, Pr.

03.04 should be set using the following formula:

Pr. 03.04 = ((meter full scale voltage)/10) x 100%

Revision August 2008, 2ELE, V1.02 4-49

Chapter 4 Parameters|

For Example: When using the meter with full scale of 5 volts, adjust Pr.03.04 to 50%. If

Pr.03.03 is set to 0, then 5VDC will correspond to Maximum Output Frequency.

03.05 Terminal Count Value Unit: 1

Settings 0 to 9999 Factory Setting: 0

 This parameter sets the count value of the internal counter. To increase the internal counter,

one of Pr.04.05 to 04.08 should be set to 12. Upon completion of counting, the specified output

terminal will be activated. (Pr.03.00 set to 10).

 When the display shows c555, the drive has counted 555 times. If display shows c555•, it

means that real counter value is between 5,550 and 5,559.

03.06 Preliminary Count Value Unit: 1

Settings 0 to 9999 Factory Setting: 0

 When the counter value reaches this value, the corresponding multi-function output terminal

will be activated, provided one of Pr.03.00set to 11 (Preliminary Count Value Setting). This

multi-function output terminal will be deactivated upon completion of Terminal Count Value

Attained.

Example 8: Use negative slope

In this example, the use of negative slope is shown. Negative slopes are used in applications for

control of pressure, temperature or flow. The sensor that is connected to the input generates a large

signal (10V) at high pressure or flow. With negative slope settings, the AC motor drive will slow stop

the motor. With these settings the AC motor drive will always run in only one direction (reverse). This

can only be changed by exchanging 2 wires to the motor.
