3) One-touch tuning execution
After the response mode is selected in (4) (b) 2) in this section, clicking the start button will start
one-touch tuning. If the start button is clicked while the servo motor stops, "C002" or "C004" will
be displayed at status in error code. (Refer to (4) (b) 5) in this section for error codes.)
Click the start button to start the one-touch tuning in the amplifier command method with the
servo-off, the servo-on will be automatically enabled, and the one-touch tuning will start. In the
one-touch tuning by the amplifier command method, an optimum tuning command will be
generated in the servo amplifier after servo-on. Then, the servo motor will reciprocate, and the
one-touch tuning will be executed. After the tuning is completed or canceled, the servo amplifier
will be the servo-off status. When the servo-on command is inputted from outside, the amplifier
will be the servo-on status.
POINT
For equipment in which overshoot during one-touch tuning is in the permissible
level of the in-position range, changing the value of [Pr. PX14 One-touch tuning
overshoot permissible level] will shorten the settling time and improve the
response.
When executing one-touch tuning in the amplifier command method, turn on
EM2. When you turn off EM2 during one-touch tuning, "C008" will be displayed
at status in error code, and the one-touch tuning will be canceled.
When executing the one-touch tuning in the amplifier command method, FLS
(Upper stroke limit) and RLS (Lower stroke limit) will be disabled. Thus, set a
permissible travel distance within a range where moving part collision never
occurs, or execute the one-touch tuning in a state in which the servo motor can
immediately stop in emergency.
When one-touch tuning is executed in the amplifier command method while
magnetic pole detection is not being performed, magnetic pole detection will be
performed, and then one-touch tuning will start after the magnetic pole detection
is completed.
