3.4 Absolute Reset Procedure
B3-10
ME0384-4A
[When performing absolute reset from host]
Perform the following procedure.
(1) Supply the control power and motor power (24V DC).
(2) Turn on the STOP signal input to cancel the drive shutoff status and set to conductive
status.
(3) Confirm that the absolute encoder error alarm is output.
(Confirm that the alarm signal “ALM” is ON.)
(4) Input the reset signal “RES” and reset the alarm.
The RES signal is processed with ON edge, but if the cause of the other alarm is not
removed, the alarm (ALM signal ON) will recur. Check the causes of the other alarms and
take appropriate actions.
(5) After confirming that the ALM signal is OFF, input the servo ON signal “SON”.
(6) After confirming that the operation ready signal “SV” is ON, input the home return signal
“HOME”. Home return motion begins. When home return is completed, the home return
complete signal HEND is output.
For the EC connection unit, confirm that the gateway status signal 0 "RUN" and operation
standby complete signals "E0RD" to "E3RD" are turned on, and then input either forward
or backward signal "ST0/ST1". The home-return operation starts. Once the home-return
operation ends and moved to the backward (or forward) end, the forward/backward signal
"LS0/LS1" should be output.
Note: For the EC connection unit, the alarm signal "*ALM" turns on in normal condition and
turns off when an alarm is generated.
Also, there is no "LNK*" or "SON" signal for the EC connection unit.
Once the power is supplied, the servo on ELECYLINDER automatically turns on.
