27. Input Filter Gain : This is a parameter setting to
regulate the response time of the drive compared
to the analog input signal.
28. For a rapid response time, it is necessary to set
the lower filter gain, while setting the higher filter
gain when there is a higher ripple in input voltage.
Setting range : 50 ~ 100 %
29. Input Gain : Input signal multiplier. In order to
fine-tune the input signal for a desired output level,
this value must be adjusted so that the maximum

Frequency jump, Band
Setting range : 0 ~ Max. Freq.
0 ~ 30 Hz
36. This is to skip certain frequency range to avoid mechanical stress that the motor is connected to.
37. As shown in the picture below, if it has a preset jump frequency of 10 Hz and a bandwidth of 5 Hz, it is not possible to set the target frequency within the range of 5.01 - 14.9 Hz. If the preset frequency increases, the driving frequency jumps when the preset frequency reaches over 15 Hz after running at 5 Hz. On the contrary, if the preset frequency decreases, the driving frequency changes when the preset frequency comes to below 5 Hz after running at 15 Hz.
38. This function is to prevent undesirable resonance that can be caused by the vibration of the gear case / motor and the output frequency of the drive.

Slip compensation, Rated slip, Rated current, No-load current
Setting range : 0 ( NO), 1 ( YES )
Setting range : 0 ~ 5 Hz
Rated slip : It is set on the basis of the rated number of rotations shown on the motor slip and the number of poles. If the rated number of rotation is 1740rpm(based on 60Hz), rated slip can be calculated as follows.
Rated slip frequency = ( 1800 - 1740 ) x No. of pole / 120 = 2 Hz
Setting range : 0.1 ~ 60 A
Motor rated current : Rated current shown on the nameplate of motor.
Setting range : 0.1 ~ 60 A

The number of retry : Number of retrial attempts
by the drive after resetting itself from a trip.
Setting range: 0 ~ 10 sec
Retry time : Time delay before the drive resets
the trip and then engages retry..
This is to prevent the motor from stopping itself due to a trip. If there is a trip, it is desirable to get into normal run by using speed search functions (F48 - F50) along with retry sequence. If the trip condition still exists after a complete set of retries, the drive stops generating the output. In this case, the drive must be reset by using ‘RST’ terminal or the Keypad of the drive. This feature enables hoist and crane to over-ride nuisance trips for its continuous operation.
Fault relay mode
Setting range : 0 ~ 3
0 : The relay does not close when there is a Lv (low input voltage) trip and during the auto retry sequence. However, it will close when the retry sequence has been completed and the fault condition remains.

Steady Speed..
7 : Prevents stall during Accel.,
Steady Speed and Decel.
Note: In case of using Dynamic Braking resistor, don’t set at .
When the stall prevention function is selected, the acceleration and deceleration time can be longer than not selected.
Setting range: 30 ~ 150 %
Function related : F35
[pic]
[pic]
Stall level: This is a ratio based on the drive rated current.
Stall prevention during Accel. : If drive detects its output current at the programmed stall level, it stops further acceleration until the output current falls below the stall level.
Stall prevention during Steady-speed operation : The drive will start to decelerate the speed if the output current of the drive reaches the stall level during Steady-Speed operation. Once the output current falls below the stall level, the drive will accelerate back to its steady-speed level.
Stall prevention during deceleration : The drive temporarily stops decelerating if DC link voltage reaches over permitted level during deceleration. Once DC link voltage falls, the drive will decelerates again. For hoisting applications, this mode is not recommended since the load is fixed. Increasing the deceleration time is rather recommended.
This function is to prevent the motor from stalling caused by overload during operation.
Overload warning level, Warning time
Setting range: 30 ~ 150 %
[pic]
Function : F35, H2
Warning level : This is a ratio based on the drives rated current. The drive will turn ON the open collector output once this level is detected.
Setting range : 0 ~ 30 sec

Function related : F35
ETH level : This is the ratio of rated motor and drive output current times constant ‘k’.
Setting range : 0 ( General), 1 ( Special)
Motor type : Set to , if a fan is attached to the motor shaft. If separate power drives the motor fan, set to .
It is recommended to consider methods for separate motor cooling effect, especially when operating at low speed. ETH level is set according to the rated current shown on motor’s nameplate. The standard value of ETH operation is 60Hz, 1 min. Based on ETH level setting value.
Setting level(%) = k x x 100
( k = 1.0 : 50 Hz power source, = 1.1 : 60 Hz power source )
Example :
If the drive is 2.2kW (11Amp.) and the motor is 2.2kW (8.6Amp.), the ETH level is set to 86% when running with 60Hz. Drive will cease output and make ETH trip if the output current lasts more than 1 minute over 8.6 Ampere.
Retry selection in case of IPF, Accel./Decel. time, Block time
Setting range:0 (No), 1 (Yes)
Retry selection in IPF : The drive will engage in to Auto Retry mode after instantaneous power failure(IPF). This will enable the hoist to lift its load without interruption during instantaneous power failure.

[pic]
Setting range : 0 ~ 5 sec
Block time : A time delay before the drive engages in speed-search mode after IPF, also used when the trip takes place during auto-retry.
This function is to restore the motor speed back to its previous speed prior to its IPF (more than 15msec.) trip. This mode is not valid if there is low voltage or less than 15msec of IPF.

If trip is removed by using RESET key, information such as the trip content, frequency output, and current at the time of the trip are saved in ‘H17’. It is possible to get the information about the frequency and by using FUNC keys.
5.4 Protective function
|Protective function |Description |
|Over-current protection |Drive output is cut off, if the output current reaches over 200% of the drive’s rated current |
| |! Caution : There is a possibility of damage in power module(IGBT). Be sure to check the drive|
| |completely before power up sequence |
|Over-voltage protection |Drive output is cut off, if regenerative energy due to the motor deceleration or generative load|
| |makes DC voltage (DC Link voltage) over its limit. |
|Current limit protection |Drive output is cut off, if the current reached over 180% of the drive’s rated current during |
| |the time set at F43. (refer to F43). |
| | |
|Heat-Sink over-heat |Drive output is cut off. Overheat caused by failed cooling effect is detected by the temperature|
| |element which is attached to a heat-sink. |
|ETH |Drive output is cut off when there is any over-current 100% greater than that of rated current |
| |(F44 - F46). Overload capacity: 150% / 1 min. |
|External fault signal |External Trip terminal is set. Check ‘H1’. |
| | |
|Under-voltage protection |Since there is a lack of torque or motor overheat caused by the voltage drop of the drive, Drive|
| |output is cut off when DC voltage (DC Link Voltage) of control circuit falls below 200V. |
|BX protection |BX terminal is closed. Drive will restart when BX is open. |
| | |
|CPU error |It cuts off the output of the drive when there is an error in main CPU caused by system noise. |
| |It is possible to remove the error by pressing STOP/RESET key. |
|Communication error |Error in the communication between the main unit and the key-pad, which has no influence to the |
| |drive operation. It can be removed by replacing the key-pad. |

7. Maintenance
Since the iG series is an industrial electronic product with advanced semiconductor element, it is likely to be influenced by temperature, humidity, and vibration and also there can be some trouble caused by aging parts.
To avoid them, it is recommended to perform routine inspection.
7.1 Precautions
Be sure to check the drive power input while performing maintenance.
Be sure to operate only after checking discharge of power, because bus capacity in electronic circuit is still charged even after the power is turned off.
It is possible to measure correct output voltage only by using rectifier voltage meter. Other voltage meters including digital voltage meter are likely to display error value caused by high frequency PWM output voltage of the drive.
7.2 Routine inspection
Be sure to check the following before operation.
4. The condition of the place to install.
5. The condition of the cooling facilities.
6. Abnormal vibration.
7. Abnormal over-heat.
7.3 Periodical inspection
Any loose bolt and nut or rust caused by surrounding conditions?
Tighten up or replace.
Any deposit in inside of the drive or cooling fan.
Remove the deposit by using air.
Any deposit in the drive’s PCB.
Remove the deposit by using air.
Any abnormal contact in various connectors of the drive‘s PCB.
Check the connection of the connector.
Check the rotating condition of the cooling fan, the size and capacity of capacitor, and the connection of magnetic contactor.
Replace it if there is any abnormality.
