Step data ALM2
(1-051)
B
RESET
input
<Contents>
For an operation for a specific step data no., the requested
number of the step data is not registered. (When operation is
commanded through PLC, this alarm will be generated
depending on the input signal interval and the holding time of
signals)
<Countermeasure>
(1)
Make sure that the “Movement MOD” of the st
ep
data is not
“Blank (Disabled)”.
(2) Process delay of PLC or scanning delay of the controller
may occur. Keep the input signal combination for 15 ms (30
ms if possible) or longer.
“
9.1 Positioning operation
”
Stroke limit
(1-052)
B
RESET
input
<Contents>
The electric actuator goes out the stroke limit specified by the
basic parameters, “Stroke (+)” and “Stroke (-)” if it performs the
requested operation.
(Including JOG operation after return to
origin)
<Countermeasure>
Make sure that the basic parameter
,
“Stroke (+)” and “Stroke
(-
)” are consistent with the distance of the electric actuator
movement specified in the step data.
Caution
If the operation method of step data is INC, take care with the
position where operation starts and the travel distance.
Pushing ALM
(1-096)
C
RESET
input
<Contents>
In the pushing operation, if push back is bigger than pushing
operation, the push back is requested.
<Countermeasure>
Increase the distance from the pushing operation origin position
to the object being pushed. Or, increase the pushing force.
ORIG ALM
(1-097)
C
RESET
input
<Contents>
Return to origin is not completed within the set time.
<Countermeasure>
- If the ORIG mode of the return to origin parameter is 1, the
models of the controller and the electric actuator may not
match. Check the product model. Also, the motor shaft may
be loosened. Please refer to the operation manual for the
electric actuator.
- If the ORIG mode of the return to origin parameter is 2 or 3,
check if the sensor mounting and the cable connection of the
sensor are correct.
Servo off ALM
(1-098)
C
RESET
input
<Contents>
While the servo is off (when EMG terminal is not energized), the
return to origin operation, positioning operation, pushing
operation or JOG operation is requested. When the
“Maximum
speed
” of the basic parameter is set low, change the speed to
the maximum speed of the electric actuator to check the
operation.
<Countermeasure>
Command operation while the servomotor is on (SVRE output
is on). Apply 24 VDC to the EMG terminal.
