The electric
actuator does
not move to the
correct
position.
Incorrect origin
position
If it is a pushing operation,
repeat return to origin
operations several times
to check if the electric
actuator returns to the
origin correctly.
Perform the return to origin position
operation several times to check the origin
position.
Take measure to make the
electric actuator
operates normally (remove foreign matters
that interferes with the
electric actuator
movement, etc.)
Inappropriate
basic
parameters
Check that the parameter
values are appropriate
and the program is
correct.
Check the max. speed, acceleration speed,
and deceleration speed of the electric
actuator and be sure to input the correct
parameters.
→ 7. Setting Data Entry
Signal timing
For the single-pulse
mode, check whether the
pulse is input
simultaneously with
operational direction
switching.
Input the pulse after 15 ms or more (30 ms
is recommended) has passed after the
direction is switched.
Incorrect pulse
input
Check that the number of
input pulses recognized
by the LECPA is the same
as the number of pulses
output from the controller
setting kit or the teaching
box.
2.5 Procedure (until
operating the electric
actuator)
<When the number of pulses match>
Correct the calculation method for the
number of pulses and electric gear setting.
<When the number of pulses do not
match>
Correct the pulse counts, frequency, and
output mode of the pulses output from the
controller setting kit/teaching box to make
them compatible with the LECPA parameter
settings and specifications.
Incorrect pulse
detection
Check for equipment
which generates strong
electrical noise around the
product.
Reduce the amount of noise generated
from the surrounding equipment. Route the
LECPA I/O cable separately from the noise
source (surrounding equipment and their
cables).
The electric
actuator does
not move
correctly.
Wiring fault
Is the wiring connected
correctly?
Check if the wiring is connected correctly or
if there is broken wire or short-circuit by
referring to this Operation Manual. Correct
the wiring and check that the input/output of
each signal is correct.
Separate the power supply for the
CN1driver and the CN5 I/O signal power
supply.

→ 6.4 Parallel I/O Wiring Example
Inappropriate
specifications
Check that the
combination of the electric
actuator and driver is
correct?
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the driver.
→ 3. Product Specifications
Signal timing
Check the timing of the
signal from the PLC to the
driver.
PLC processing delay and drver scan delay
are generated. Please ensure an interval of
15ms (30 ms if possible) or more between
input signals, and maintain the signal state.
