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.

Figures 1.2 (a) and 1.2 (b) show the connection between the power connector and drive control
circuits in SBT L450U and L450S models, respectively. In L450S model, the drive can be used in a
single phase. It is also possible to set and run the drive via the digital operator without connecting
digital I/O wiring. Refer to chapter 2 for further details.

 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.
