Detail Drive Configuration and Operation Chapter 1
[Mtr TrqCurr Ref ] is a real parameter expressed in per unit. Therefore a value of
1 corresponds to 100% motor torque. [Anlg Out1 Real] is used because [Mtr
TrqCurr Ref ] is a real parameter.
[Anlg Out1 Scale] is set to 0.1 per 1V so that when [Mtr TrqCurr Ref ] = 1p.u.,
the analog output = 1 / 0.1 = 10V.
Example Configuration 2:
This configuration sends [Position Error] out to a 0-10V analog output signal.
• [Anlg Out1 Integer] is linked to [Position Error]
• [Anlg Out1 Scale] is set to 214748664.8 per Volt
[Position Error] is an integer parameter with a range from -2147483648 to
+2147483648. [Anlg Out1 Integer] is used because [Position Error] is an integer
parameter.
[Anlg Out1 Scale] is set to 214748364.8 per Volt so the analog output will give -
10V when the position error is -2147483648 and will give +10V when the
position error is +2147483648.
Auto/Manual The Auto/Manual function on the LCD HIM is not functional for the
PowerFlex 700S drive.
Autotune Auto-tuning is a procedure that involves running a group of tests on the motor/
drive combination. Some tests are checking the drive hardware while others
configure the drive parameters to maximize the performance of the attached
motor.
The auto-tuning procedure can be completed using the Start-Up menu of the
HIM. Please refer to Chapter 2 - Start-Up of the PowerFlex 700S High
Performance AC Drive Phase I Control - User Manual, publication
20D-UM001 , for information on starting-up the PowerFlex 700S AC drive and
running the auto-tune procedure.
Autotune - Start-Up Menu
The Start-Up menu prompts you for information and yes/no responses as
required. The “Motor Control,” “Motor Data,” “Feedback Configuration,”
“Power Circuit Test,” “Direction Test,” “Motor Tests,” and “Inertia Measure”
submenus of the Start-Up Menu are all related to the autotuning of the drive/
motor combination and will be covered in this section.
