b) Interrupted before HEND becomes ON in the home position return
The home position return interrupts in the following situations;
○
Make the servo OFF in the home position return with the operation
○
Perform the deviation counter clearing in the home position return with the operation
○
Input the drive restriction and perform the deviation counter clearing in the home position return with the operation
○
Alarms occur and servo OFF in the home position return with the operation
c) “Incremental system” is selected to “Selection of an encoder system” after the power is supplied to the drive
d) “Absolute system” is selected for “Selection of an encoder system”, but the multi-rotation data of the encoder disappear.
・
The minimum OFF time of the signal is 3ms.
2) MEND completion (15 pins)(Note 1)
・
When perform the home position return at servo ON, confirm if you can start the home position return or not. Please make
sure this signal is ON before home position return.
・
OFF at servo OFF.
・
The minimum OFF time of the signal is 3ms.
3) MEND/T-LIMIT completion / torque limit (Valid when positioner I/O is set to Item 1).
・
This parameter is valid when positioner I/O is set to Item 1.
(For the setting of Item 1, refer to
「
Appendix 3 SV-E3 special I/O setting
」)
・
Be ON either MEND or T-LIMIT is ON.
・
This signal, used in the device of torque limit, including stopper, is T-LIMIT. And the other operations is used as MEND signal.
As T-LIMIT, the torque limit TLSEL1 is ON and as MEND, TLSEL1 is OFF.
Set the following parameters first when using this signal.
“Torque command limit override selection”(No. 144. 0): “1: Enable”
“Selection of Torque limit state output mode(No. 144. 1)”: “2 : Torque command limit Override 2”
Note 1) Action at home position return completion(No. 647. 1
)
: HEND and MEND
1) When set the Action at home position return completion(No. 647. 1
)
to “1 = Move”
After the base signal for home position is detected, it will decelerate to stop and HEND is ON at home position return
completion.
Then shift to home position according to the action of home position return completion, the MEND becomes ON after the
operation has been completed. The ABS position command becomes the home position return position data after the
operation has been completed.
