Absolute encoder system
MR-J3A corresponds to the absolute encoder system. Therefore, BS system can also
be equivalent to the absolute encoder system.
13.1.
Setup
13.1.1.
Setup to BS controller
In the tool type of absolute encoder system, "A" is attached to the end of tool
type form.
13.1.2.
Setup to MR-J3A
PA03 is set as 0002 by parameter setup. In the 1st power supply injection after
performing this setup, the alarm of AL.25-" absolute position disappearance"
will be generated at MR-J3A. The release method of the alarm is mentioned
later.
13.1.3.
Wearing of a backup battery
Please equip CN4 of MR-J3A with the backup battery of exclusive use.
13.2.
The alarm release method
The alarm of AL.25 "absolute position disappearance" will occur in MR-J3A by
a power supply injection of the first time after absolute encoder system setup,
consumption of a backup battery and disconnection of an encoder cable. AL.25
will be canceled if the power supply of MR-J3A is re-switched on after
removing some causes of alarm.
Important
If wiring connection of the BS system is made normally and the
power supply of BS controller is switched on when AL.25 occur, BS controller
will be in the state where origin is not completed. In this case, execution of a
program etc. cannot be performed unless origin operation is completed. When
AL.25 occurs, please perform origin operation after re-switching on a power
supply.
