Problem
Possible
cause
Investigation method and location of
possible cause
Countermeasure
Required
speed is
not
achieved
Incorrect
parameters
Check that the parameter values are correct.
Review the maximum speed and the
maximum acceleration of the actuator.
Modify the values of the parameters and test
the operation.
Operation
pattern is not
suitable.
Check if a trapezoidal
acceleration/deceleration is programmed for
the actuator operation. In case of such
operation, the actuator may start slowing
down before it reaches the maximum speed.
Modify the setting to make the moving
distance longer or the acceleration larger.
Influence
of a
magnetic
force
Check if there is equipment which generates
a 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.
Unsuitable
specification
Check if the controller’s specifications are
appropriate, the power supply is suitable and
the controller is compatible with the actuator.
If a blank controller is used, check that the
written data is identical with the actuator
used.
Check that the product number of the actuator
used matches with the actuator which is
applicable to the controller before use.
If a blank controller is used, write the data,
which is identical with the product number of
the actuator used.
Voltage
drop
Check for a 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
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 if the power supply is
"inrush-current control" type.
If necessary, replace the power supply.
