For Auto-Tuning enter the Auto-Tuning menu and perform the steps shown in the figure below. The number of name
plate data to be entered depends on the selected type of Auto-Tuning. This example shows Rotational Auto-Tuning.
If Auto-Tuning can not be performed for some reason (no-load operation impossible etc.), then set up the maximum
frequency and voltage in the E1- parameters and enter the motor data manually into the E2- parameters.
NOTICE: The Safe Disable inputs must be closed during Auto-Tuning.
 External Reference Selection and Acceleration/ Deceleration Times
 Frequency Reference Selection (b1-01)
Set parameter b1-01 according to the frequency reference used.
Rotational Auto-
Tuning for V/f
Control
T1-01 = 3
• Recommended for applications using Speed Estimation
Speed Search or using the Energy Saving function in V/f
Control.
• Assumes motor can rotate while Auto-Tuning is
executed. Increases accuracy for certain functions like
torque compensation, slip compensation, Energy Saving,
and Speed Search.
YES YES N/A N/A
CAUTION
Never touch the motor until the Auto-Tuning is finished. Even thought the motor may not be rotating when Auto-
Tuning, voltage is still applied to the motor during the tuning process.
b1-01 Reference source Frequency reference input
0 Operator keypad
Set the frequency references in the d1- parameters and used digital inputs to switch over
between different reference values.
1 Analog input Apply the frequency reference signal to terminal A1, A2, or A3.
2 Serial Comm. Serial Communications using the RS422/485 port
3 Option Board Communications option card
