Caution For One-Touch Tuning - Mitsubishi MR-JE-10B Instruction Manual

6. NORMAL GAIN ADJUSTMENT

6.2.3 Caution for one-touch tuning

(1) Caution common for user command method and amplifier command method
(a) The tuning is not available in the torque control mode.
(b) The one-touch tuning cannot be executed while an alarm or warning which does not continue the
motor driving is occurring.
(c) The one-touch tuning cannot be executed during the following test operation mode.
1) Output signal (DO) forced output
2) Motor-less operation
(d) If one-touch tuning is performed when the gain switching function is enabled, vibration and/or
unusual noise may occur during the tuning.
(2) Caution for amplifier command method
(a) Starting one-touch tuning while the servo motor is rotating displays "C006" at status in error code,
and the one-touch tuning cannot be executed.
(b) One-touch tuning is not available during the test operation mode. The following test operation modes
cannot be executed during one-touch tuning.
1) Positioning operation
2) JOG operation
3) Program operation
4) Machine analyzer operation
(c) After one-touch tuning is executed, control will not be performed by commands from the servo
system controller. To return to the state in which control is performed from the servo system
controller, reset the controller or cycle the power of the servo amplifier.
(d) During one-touch tuning, the permissible travel distance may be exceeded due to overshoot, set a
value sufficient to prevent machine collision.
(e) When Auto tuning mode 2, Manual mode, or 2 gain adjustment mode 2 is selected in [Pr. PA08 Auto
tuning mode], the load to motor inertia ratio will not be estimated. An optimum
acceleration/deceleration command will be generated by [Pr. PB06 Load to motor inertia ratio] at the
start of one-touch tuning. When the load to motor inertia ratio is incorrect, the optimum
acceleration/deceleration command may not be generated, causing the tuning to fail.
(f) When one-touch tuning is started by using USB communication, if the USB communication is
interrupted during the tuning, the servo motor will stop, and the tuning will also stop. The parameter
will return to the one at the start of the one-touch tuning.
(g) When one-touch tuning is started via the controller, if communication between the controller and the
servo amplifier or personal computer is shut-off during the tuning, the servo motor will stop, and the
tuning will also stop. The parameter will return to the one at the start of the one-touch tuning.
(h) When one-touch tuning is started during the speed control mode, the mode will be switched to the
position control mode automatically. The tuning result may differ from the one obtained by executing
tuning by using the speed command.
