◆ T: Motor Tuning
Enter data into the following parameters to tune the motor and drive for optimal performance
S6: Power KEB Function
S6 parameters determine how the Power KEB type of KEB operates.
S6-01 DC Bus Capacity Sets the size of any external capacitors that were added. 0 to 65000
<11> AA A6D0228
S6-02
Motor Acceleration
Time
The time required for the motor to accelerate from zero
up to the maximum frequency at the rated torque. If E2-
11 is changed by the user or by performing Auto-
Tuning, then S6-02 will automatically be set to the value
of a Yaskawa 4-pole motor.

S6-03 Load / Inertia Ratio
Enter the ratio between the inertia of the load and the
inertia of the motor the drive is running.

S6-04
DC Bus Adjustment
Gain
Sets the gain to keep the voltage in the DC bus at the
target level. If overvoltage or undervoltage is a problem
at the start of Power KEB, gradually increasing S6-04 in
increments of 0.1 may help.

Accel/Decel Calculation
Gain
Sets the gain used to calculate the acceleration and
deceleration rates used for Power KEB, overvoltage
suppression, and “intelligent” method of Stall
Prevention during deceleration (L3-04 = 2).

<2> Default setting is determine by the control mode set in parameter A1-02. The value shown is for A1-02 = 0-V/f Control.
<9> Default setting is determined by the motor code set to parameter E5-01.
<11> Default setting is determined by the drive model selection set in parameter o2-04.
<15> Parameter can be changed during run.
<17> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<28> Parameter value is changed if E2-11 is manually changed or changed by Auto-Tuning.
<33> Default setting is determined by the drive model selection set in parameter o2-04. and C6-01, Drive Duty Selection.

Selection
Selects which set of motor parameters are used and set during
Auto-Tuning. If Motor 2 selection (H1- = 16) is not
selected, this parameter will not be displayed.
