One-Touch Tuning Error - Mitsubishi Electric MELSERVO J5 Series User Manual

One-touch tuning error

On MR Configurator2
If a tuning error occurs during the tuning, the one-touch tuning is stopped. At this time, as the error code is displayed in the
error code status, check the cause of the tuning error. Stop the servo motor before executing one-touch tuning again. In
addition, perform the one-touch tuning after the moving part is returned to the tuning start position.

Error description
The "Stop" button was clicked during one-touch
tuning.
The overshoot amount is larger than the value set in
[Pr. PA10 In-position range] and [Pr. PA25 One-
touch tuning - Permitted overshoot level].
The one-touch tuning in the user command method
was attempted during servo-off.
The servo amplifier was set to the servo-off status
during the one-touch tuning.
The one-touch tuning was attempted when the
torque mode was selected in the control modes.
Control switching from the position mode to the
speed mode was attempted during one-touch tuning.
One cycle time during the operation exceeds 30 s.
The command speed is slow.
The dwell time during continuous operation (stop
time between commands) is short.
The estimation of the load to motor inertia ratio at the
one-touch tuning has failed.
The load to motor inertia ratio cannot be estimated
due to the effect of oscillation or others.
One-touch tuning was attempted to start by the
amplifier command method under the following
speed condition.
• Servo motor speed: 20 [r/min] or higher
• In MR-J5W-G, servo motor speed of other axes:
20 [r/min] or higher
Handling example

Increase the in-position range or the overshoot permissible
level.
Perform the one-touch tuning in the user command method in
servo-on status.
Do not turn the servo off during one-touch tuning.
Select the position mode or velocity mode for the control mode,
and then perform the one-touch tuning without control
switching.
Set one cycle time during the operation (time from the
command start to the next command start) to 30 s or less.
Set the servo motor speed to 100 r/min (mm/s) or higher. An
error is less likely to occur if the command speed is higher.
Set the dwell time to 200 ms or more.
An error is less likely to occur as the setting time is longer.
Drive the servo motor under the following conditions:
• Time to reach 2000 r/min (mm/s) is the acceleration/
deceleration time constant of 5 s or less.
• Speed is 50 r/min (mm/s) or higher.
• The load to motor inertia ratio to the servo motor is 100 times
or less.
• The acceleration/deceleration torque is 10 % or more of the
rated torque.
Set [Pr. PA08.0 Gain adjustment mode selection] to "3" (manual
mode), and set the correct value of load inertia moment ratio to
[Pr. PB06 Load to motor inertia ratio], then execute the one-
touch tuning.
Perform the one-touch tuning in the amplifier command method
when the servo motor is at a stop.
