17.2 Position / Speed problems
Problems
Possible
causes
Investigation method
Countermeasures
The actuator
does not
move to the
correct
position.
Incorrect
origin
position
For a pushing operation, repeat the Return to
origin operation several times to check that
the actuator returns to the origin correctly.
Check the actuator operation (if foreign
matter is caught in the product etc.).
Incorrect
parameters
Check that the controller parameters are
appropriate and the program is correct.
Review the maximum speed, the
maximum acceleration and maximum
deceleration of the actuator.
Modify the parameters and test the
operation.
-> 9. Settings Data Entry
Unsuitable
specification
Check that the controller parameter
settings for the product model and power
supply specification are appropriate for the
actuator connected.
Check that the controller parameters for the
product number matches with the actuators.
Check that the power specification is correct.
-> 4. Product Specifications
The actuator
does not
move
correctly.
Incorrect
wiring
Check that the wiring is connected
correctly?
Refer to this operation manual to confirm
wiring, and check for broken wires and
short-circuits.
Correct the wiring so that the input/ output
of each signal is performed appropriately.
Prepare a separate power supply for the
main control, motor drive and motor
control, and input/ output signals.
-> 2.3 Product configuration
-> 6. Power supply connector
Unsuitable
specification
Check that the controller parameter
settings for the product modelandpower
supply specification are appropriatefor
the actuator connected.
Check that the controller parameters for
the product number matches with the
actuators. Check that the power
specification is correct.
-> 4. Product Specifications
Signal timing
Check the timing of the signal from the
PLC to the controller.
Leave an interval of 15ms or more
(recommendation is 30 ms) between
signals and maintain the state of the signal
for 15ms or more (recommendation is 30
ms), because PLC processing delays and
controller scanning delays can occur.
->10.7 PLC output signal response time
Data not
stored
correctly
Check that the data (step data, parameters)
is stored correctly. Do not turn off the
controller power supply or remove the USB
cable while data is being stored.
Input the correct data (step data,
parameters) again and confirm operation.
-> 4.2 Parts Description
-> 9. Settings Data Entry
Required
speed is not
achieved
Incorrect
parameters
Check that the parameter values are correct.
Review the maximum speed and the
maximum acceleration and deceleration of
the actuator.
Correct the parameter values and test the
operation.
-> 9. Settings Data Entry
Operation
pattern is not
suitable.
Check if a triangular 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 movement
distance longer or the acceleration higher.
-> 9. Settings Data Entry
Unsuitable
specification
Check that the controller parameter
settings for the product model and power
supply specification are appropriate for the
actuator connected.
Check that the controller parameters for the
product number of the actuator matches
the actuator connected. Check that the
power supply specification is correct.
-> 4. Product Specifications
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 the motor control 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 an “inrush-current protection”
type.
