•
Make sure that a mechanical brake on the motor shaft is not locked
•
The maximum motor load must be 30% of the rated load.
•
Keep a constant speed of 30% of
E1-06 [Base Frequency]
(default value =
maximum frequency) or more for 1 second or longer.
3.
After the motor stops, examine the values of
E2-02
and
E2-03
again in the Verify
Menu or Parameter Setting Mode.
4.
Make sure that the input data is correct.
When the settings in
E2-02
and
E2-03
are different than in step 1, the drive set the
values automatically.

Precautions before Stationary Auto-Tuning for Line-to-Line Resistance
and Stator Resistance Auto-Tuning
In V/f control, when the motor cable is 50 meters (164 feet) or longer, do Stationary Auto-
Tuning for Line-to-Line Resistance.
WARNING
Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage
when the motor is stopped. Do not touch the motor until Auto-Tuning is complete. If you touch a motor that
is energized, it can cause serious injury or death.
■
Precautions before Using Deceleration Rate Tuning and KEB Tuning
Before Deceleration Rate Tuning or KEB Tuning, check these items:
Note:
•
Do not do Deceleration Rate Tuning if you use a braking resistor unit or a regenerative converter.
•
Do Deceleration Rate Tuning and KEB Tuning with the load attached to the motor.
•
Do not do Deceleration Rate Tuning or KEB Tuning for these applications:
In Deceleration Rate Tuning and KEB Tuning, the drive will automatically rotate the motor forward and
accelerate and decelerate the motor again and again.
–
On a machine that does not let the motor rotate forward
–
In applications with a small range of operation (trolleys and other such applications that can only move
linearly)
–
Applications where sudden acceleration and sudden deceleration are not applicable.
•
To do KEB Tuning with the external main circuit capacitors connected to the drive, set
L3-26 [Additional DC
Bus Capacitors]
then do KEB Tuning.
•
Do not do KEB Tuning or Deceleration Rate Tuning if the drive is set to use
H1-xx = 16 [MFDI Function
Select = Motor 2 Selection]
. Failure to obey can cause an
ov [Overvoltage]
fault.
