■Operation
Inputting commands to the servo amplifier that satisfy the following conditions is recommended. If the one-touch tuning is
performed with commands that do not satisfy the condition are inputted to the servo amplifier, a one-touch tuning error may
occur.
Forward rotation
Servo motor
0 r/min
speed
Acceleration
time constant
Reverse rotation

■Command method and response mode selection
Select the user command method in the one-touch tuning window of MR Configurator2 and then select a response mode from
three modes. If no vibration sound occurs during tuning, perform the one-touch tuning again in the high response mode.

Description
Set 100 pulses or more in the encoder pulse unit. Setting less than 100 pulses causes the one-touch tuning error "C_04".
Set 50 r/min (mm/s) or higher. Setting less than 50 r/min may cause the one-touch tuning error "C_05".
Set the time to reach 2000 r/min (mm/s) to 5 s or less.
Set an acceleration time constant/deceleration time constant so that the acceleration/deceleration torque is 10 % or more
of the rated torque. The estimation accuracy of the load to motor inertia ratio improves as the acceleration/deceleration
torque is larger, and the one-touch tuning result is closer to the optimum value.
Set 200 ms or more. If the value is small, the one-touch tuning error "C_04" may occur.
Set 30 s or less. Setting over 30 s causes the one-touch tuning error "C_04".
Description
This mode is for a high-rigid system.
This mode is for a standard system.
This mode is for a low-rigid system.
