Instructions On One-Touch Tuning - Mitsubishi Electric MR-J5 User Manual

Instructions on one-touch tuning

Instructions on user command method [B]
• When performing one-touch tuning, connect the servo system controller with the servo amplifier or set the servo amplifier to
the test operation mode. For one-touch tuning in the test operation mode, write the results of the one-touch tuning to the
servo parameter of the servo system controller, then connect the servo system controller with the servo amplifier.
Instructions on amplifier command method
• Once one-touch tuning using the amplifier command method is performed, control by commands from a controller will not
be available. To enable control from the controller again, reset the controller, cycle the power of the servo amplifier, or reset
software.
• Set a permissible travel distance that avoids collision with the machine. In addition, the permissible travel distance may be
exceeded because of an overshoot during one-touch tuning. Therefore, set the permissible travel distance with a margin to
avoid exceeding the range of a limit switch.
• When the manual mode is selected in [Pr. PA08.0 Gain adjustment mode selection], a load to motor inertia ratio is not
estimated. Optimum acceleration/deceleration commands are generated by [Pr. PB06 Load to motor inertia ratio/load to
mass ratio] at the start of one-touch tuning. When the load to motor inertia ratio is not accurate, optimum acceleration/
deceleration commands may not be generated, causing the tuning to fail.
• When one-touch tuning is started with a USB communication, both the servo motor and the tuning will stop if
communication between MR Configurator2 and the servo amplifier is interrupted during the tuning. In addition, the servo
parameters return to the status they had at the start of one-touch tuning.
• When one-touch tuning is started during velocity mode, the mode is switched to position mode automatically. As a result,
the tuning result may differ from the results obtained by using the speed command.
• If one-touch tuning using the amplifier command method is attempted before magnetic pole detection is performed, one-
touch tuning starts after magnetic pole detection is completed.
• For the MR-J5_-_B_, write the results of the one-touch tuning to the servo parameter of the servo system controller, then
connect the servo system controller with the servo amplifier.
• When one-touch tuning using the amplifier command method is performed in the MR-J5_-_B_, FLS (Upper stroke limit) and
RLS (Lower stroke limit) are disabled. Therefore, set the permissible travel distance within the range that surely avoids
collision of the moving part, or perform one-touch tuning in a state that an emergency stop can be enabled immediately.
