Solutions

Insufficient
speed
Inappropriate
basic
parameters
Check that the parameter values
are correct.
Check the max. speed and acceleration
speed of the electric actuator and be
sure to input the correct parameters.

7. Setting Data Entry P.37
Inappropriate
step data
Is the operation pattern
trapezoidal?
In case of such operation, the electric
actuator may start slowing down before it
reaches the maximum speed. Modify the
setting to make the moving distance
longer or the acceleration larger.

7. Setting Data Entry P.37
Inappropriate
specifications
Check that the combination of
the electric actuator and
controller is correct?
If the blank controller is used,
check that the written data is
identical with the actuator used.
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.
→
3. Product Specifications P.16
If the blank controller is used, write the
data, which is identical with the product
number of the actuator used.
Influence of a
magnetic
force
Check if there is equipment
which generates the magnetic
force, such as a magnet or
electro-magnetic coil around the
actuator.
The equipment, which generates the
magnetic force, should be kept away
from the motor.
For example, keep 40 mm minimum
distance from the cylinder with auto
switch.
Voltage drop
Check if there has been any
temporary voltage drop in the
power supply.
(If there is a temporary voltage
drop in the power supply, the EMG
terminal of CN1 power connector
will turn OFF so the electric
actuator will stop. However, this
stop will be released when the
voltage recovers.)
There is a possibility of a momentary
voltage drop because the capacity of the
power supply is insufficient, or the power
supply has inrush current restraining
specification.
