Control Tuning automatically sets the parameters in
Parameters Automatically Set
C1-02 [Deceleration Time 1]
C1-08 [Deceleration Time 4]
C1-09 [Fast Stop Time]
L2-06 [Kinetic Energy Backup Decel Time]
L3-25 [Load Inertia Ratio]
*1 The drive automatically sets C1-08 [Deceleration Time 4] only when C1-11 [Accel/Decel Time Switchover Freq] ≠ 0.
*2 When L2-29 = 0 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 1], the drive will automatically adjust C1-09 [Fast
Stop Time] and will not adjust L2-06 [Kinetic Energy Backup Decel Time]. If you must not change the Fast Stop time, do not do KEB
Tuning.
*3 When L2-29 = 1, 2, or 3 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 2, System KEB Ride-Thru 1, or System
KEB Ride-Thru 2], the drive will automatically adjust L2-06 [Kinetic Energy Backup Decel Time].

Precautions before Auto-Tuning

Examine the topics in this section before you start Auto-Tuning.
■
Prepare for Basic Auto-Tuning
• You must input data from the motor nameplate or motor test report to do Auto-Tuning. Make sure that this data
is available before you do Auto-Tuning.
• For best performance, make sure that the drive input supply voltage is equal to or more than the motor rated
voltage.
Note:
Better performance is possible when you use a motor with a rated voltage that is less than the input supply voltage (by 20 V for 200 V
class models or by 40 V for 400 V class models). This is very important when you operate the motor at more than 90% of base speed,
where high torque precision is necessary. If the input power supply is equal to the motor rated voltage, the drive output voltage will not
be sufficient and performance will decrease.
• Push
on the keypad to cancel Auto-Tuning.
• If a Safe Disable input signal is input to the drive during Auto-Tuning, Auto-Tuning measurements will not
complete successfully. If this occurs, cancel the Auto-Tuning, then do it again.
•
Table 4.16 shows the status of multi-function input/output terminals during Auto-Tuning.

*1 When you set a terminal to H2-xx = E [MFDO Function Selection = Fault], it will function the same as during usual operation.
WARNING! Crush Hazard. Wire a sequence that will not let a multi-function output terminal open the holding brake during
Stationary Auto-Tuning. If the holding brake is open during Stationary Auto-Tuning, it can cause serious injury or death.
WARNING! Sudden Movement Hazard.. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load
can move suddenly and cause serious injury or death.
