SLV Mode (Sensorless Vector Control)
Enter the motor data in parameter group 17 for SLV control mode (00-00) and perform auto-tuning.
In SLV mode, the V/F curve normally does not have to be re-adjusted after a successful auto-tune.
The maximum output frequency setting 01-02 (Fmax), base frequency 01-12 (Fbase), minimum output frequency 01-
08 (Fmin), maximum output voltage 01-03 (Vmax) or base output voltage 01-13 (Vbase) can be manually adjusted
but the voltage is automatically adjusted by the internal current controller.
Set the base frequency (01-12, Fbase) to the motor rated frequency on the motor nameplate.
Perform the auto-tuning procedure after adjusting parameters 02-19 or 17-04 to reduce the voltage at no-load
operation.
Motor jitter can be reduced by lowering the no-load voltage which will increase the current.

Torque Boost (01-10)
In V/F mode, the AC Drive automatically adjusts the output voltage to increase output torque during start or load
changes based on the calculated motor voltage loss.
Initial Setup
For Variable Torque / Normal Duty applications, set parameter 01-10 to an initial value of 0.5.
For Constant Torque / Heavy Duty applications, set parameter 01-10 to an initial value of 1.0.
01-10 Torque compensation gain
This parameter sets the torque boost for motor 1.
