Automatic Operation Mode - Mitsubishi Electric MR-JE-*C Instruction Manual

12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
No. Start-up sequence
5 Gain adjustment Rotation ripples (speed
fluctuations) are large
at low speed.
Large load inertia
moment causes the
servo motor shaft to
oscillate side to side.
Note. Refer to "MELSERVO-JE Servo Amplifier Instruction Manual (Troubleshooting)" for details of alarms and warnings.

12.5.2 Automatic operation mode

(1) Automatic operation mode
(a) Command method
Select the point table that has been set in advance with an input signal to start operation with ST1
(Forward rotation start) or ST2 (Reverse rotation start). [Pr. PT01] and the auxiliary function of the
point tables enable the absolute value command method or incremental value command method to
be selected.
1) Absolute value command method
As position data, set the target address to be reached.
Setting range: -999999 to 999999 [×10
-999999 to 999999 [×10
-999999 to 999999 [pulse]
-999999
Setting range of the position data
STM
[×10
2) Incremental value command method
As position data, set the travel distance from the current address to the target address.
Setting range: 0 to 999999 [×10
0 to 999999 [×10
0 to 999999 [pulse]
Current address
Position data = |Target address - Current address|
Fault
Make gain adjustment in the
following procedure.
1. Increase the auto tuning
response level.
2. Repeat acceleration and
deceleration several times to
complete auto tuning.
If the servo motor can be run
safely, repeat acceleration and
deceleration three times or more to
complete auto tuning.
