SBT Electric AC Drive
SBT- L450U / L450S User Manual
SBT-L450 is a general AC drive produced by Sana Barque Tavan company, capable of driving AC
motors up to 24A. The drive provides necessary functions to ensure smooth and reliable operation of
the motor at various speeds. In this manual, all functions are introduced and explained in detail. The
first chapter is dedicated to the initial settings and Auto-tuning, which calculates control parameters
required to drive the AC motor. The second chapter explains the drive parameters and features. In the
third chapter, procedures required to set the drive for elevator applications are explained. Fault
diagnosis is also included in this chapter. Please read the manual carefully to tune the drive correctly.

 Menu structure
The drive panel has four display screens that cover user-accessible drive features. Hereafter, these
menus are explained:
■ Monitoring:
Monitor parameters let the user view various aspects of drive performance using the digital operator
display. The values are updated online according to the drive condition.
■ Auto-tuning
Based on the required motor parameters shown in this menu, the drive is capable of calculating
necessary control parameters to run the motor efficiently.
■ Setting
In the setting menu, the user can edit and verify parameter settings. The number of accessible
parameters is based on the control method set in A1-02.

10
■ Modified Parameters
The parameters which have been modified and changed since the startup of the panel are shown in
this menu. If the driver turns off or the panel resets, the list will be cleared.
 Auto-Tuning
The drive offers Auto-Tuning for induction motors. The type of Auto-Tuning used differs further
based on the control mode and other operating conditions.
Note: The drive will only show Auto-Tuning parameters that are valid for the control mode which has
been set in A1-02.
■ Auto-Tuning for Induction Motors
This feature automatically sets the motor parameters E1-** and E2-** for an induction motor.

■ Basic Auto-Tuning Preparations and Precautions
WARNING! Electrical Shock Hazard. Do not touch the motor during Auto-Tuning. Lethal
voltages may be present on the motor case. Failure to comply may result in serious injury from
electrical shock.
WARNING! Electrical Shock Hazard. When executing Stationary Auto-Tuning for motor data,
the motor does not rotate, however, power is applied. Do not touch the motor until Auto-Tuning
is completed. Failure to comply may result in death or serious injury from electrical shock.
Note: In the automatic calculation of encoder offset, although the test is in static mode, the
mechanical brake must be in open condition and if the motor is connected to a load, it must be
adjusted to be balanced on both sides. ( Do not move to the desired position by opening the brakes )
• When using a motor contactor, make sure it remains closed during the Auto-Tuning process.
• Ensure Base_Block signal is ON when performing Auto-Tuning.
• Ensure the motor is securely mounted and bolted in place prior to Auto-Tuning.
• To cancel Auto-Tuning, press the STOP key on the digital operator.

11
• Make sure motor nameplate data is readily available before Auto-Tuning the drive. Auto-
Tuning requires the user to input data from the motor nameplate or motor test report.

will be performed by the drive in this situation.
Setting 1: Enable
If this parameter is set to 1, the driver will perform a light load direction test in rescue mode. Any
direction command issued from the control center will be ignored by the driver.
C: Tuning
C parameters are used to set the acceleration and deceleration characteristics, as well as jerk. Other
parameters in this group cover setting for torque compensation and PI controller in closed-loop
control.
 C1: Acceleration and Deceleration Ramps
■ C1-01 to C1-04 and C1-09: Accel, Decel Ramps 1 and 2 and Fast Stop Ramp
Five parameters can be set in the drive for tuning acceleration and deceleration ramp. Acceleration
ramp parameters always set the ramp or time to accelerate from 0 to the maximum speed.
Deceleration ramp parameters always set the ramp or time to decelerate from the maximum speed to
0.
In this version (SBT-L450U), C1-01 is used for acceleration time. C1-02 is used when the motor
decelerates from any speed to any other speed (except nominal and leveling speed to zero speed). C1-

16
04 is used when the motor decelerates from leveling speed to zero speed. C1-09 determines the
deceleration ramp from nominal speed to zero speed.
Note 1: If C1-02=0, drive coast to stop
Note 2: If C1-04=0, deceleration from leveling speed will be set according to the value set in
C1-02.
Note 3: By setting C1-09 to zero, if the motor speed shifts from its nominal speed, the drive
immediately applies the brake and coasts to stop.

The transition time between accelerating and decelerating ramps is expressed by discrete numbers in
SBT-L450U. Eight S-curve settings are available, and are expressed as below:
0: No S Curve
1: Very low
2: Low
3: Intermediate 1
4: Intermediate 2
5: Intermediate 3
6: High
7: Very high
Adjusting low numbers leads to shock while high numbers slow the operation. The optimum
operation can be obtained by setting these parameters to 3 or 4.
C4: Torque Compensation
The torque compensation function compensates for insufficient torque production at start-up or when
a load is applied.
Note: Set the motor parameters (E2-**) and V/f pattern properly before setting torque compensation
parameters.

Although this parameter rarely needs to be changed, it may be necessary to adjust the torque
compensation gain in small steps of 0.05 in the following situations:
• Increase this setting when using a long motor cable, or when the starting torque is not high enough
to accelerate the motor.
• Decrease this setting when motor oscillation occurs.
Adjust C4-01 so that the output current does not exceed the drive rated current.

Although C4-02 rarely needs to be changed, adjustments may be necessary in the following situations:
• Increase this setting if the motor vibrates.
• Decrease this setting if the motor responds too slowly to changes in the load.
C5: Speed Control Loop
These parameters are accessible only in the closed-loop control mode (A1-02=3).
The Speed control Loop Controls the motor speed in CLV and CLV/PM control modes. It adjusts
torque reference in order to minimize the difference between speed reference and actual motor speed.

which after the auto-tuning, they will be adjusted by the drive automatically.

Setting 0: Normal V/f
In this mode, the drive uses V/f curve based on Maximum Voltage (E1-05) and Maximum frequency
(E1-04). In all reference speeds, this ratio is kept constant.
Setting 1: Torque Compensation
In this mode, the torque is increased to prevent motor stall under heavy loads.
Setting 2: Manual Curve
In this mode, the user can adjust the voltage-speed curve by setting parameters E1-05 through E1-13.
Be careful to set these parameters correctly, otherwise, the motor will show unexpected behavior or
overload fault will occur due to the saturation of the motor magnetic core.
Setting 3: Boost Manual Curve (Recommended)
In this mode, the voltage-speed curve is set according to parameters E1-05 through E1-13, and
starting torque is increased to prevent motor stall under heavy loads. Besides, voltage offset could be
added to all points in the curve by using E1-03. The voltages-speed curve will be according to Fig.
2.2. Use this option when the motor is under heavy loads, or high starting torque is required.

The voltage-speed curve set by parameters E1-05 through E1-13 could be further modified by adding
a constant voltage. The amount of added voltage could be set in E1-03. If the motor stalls, increase
voltage offset to increase the torque. Note that E1-03 is used when E1-02 is set to 3 or 1.

 E2: Motor Parameters
These parameters contain the motor data for induction motors. They are set automatically when Auto-
Tuning is performed.
■ E2-01: Motor Rated Current
Used to protect the motor and calculate drive control parameters. Set E2-01 to the full load amps
(FLA) stamped on the motor nameplate. If Auto-Tuning completes successfully, the value entered to
T1-04 will automatically be saved to E2-01.

■ E2-03: Motor No-Load Current
Sets the no-load current for the motor in amperes when operating at the rated frequency. The drive
sets E2-03 during the Auto-Tuning process. Please note that if this parameter is set to 0, output phase
loss fault detection will be disabled.
