Operation

intermittently
Alarm
generated
Check if the controller has generated an
alarm? Check the type of alarm, referring
to this manual.
Refer to thismanual and take appropriate
measures.
-> 11. Alarm detection
Incorrect
wiring
Check that the wiring is connected
correctly?
Refer to this 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.

-> 5. Power supply connector
-> 6.4 Parallel I/O Wiring Example
Electrical
noise
Connect to Ground correctly.
Avoid bundling the cables.
Refer to this manual and take appropriate
measures.
-> 4.4 Mounting
Incorrect
parameters
Check that the parameter values are
correct.
Check that the appropriate parameters
are used for the actuators connected.
Modify the values of the parameters and test
the operation.
-> 7. Settings Data Entry
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 in 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.
-> 4. Product Specifications
Failure of
pushing
operation.
Check that the INP output turns on during
a pushing operation.
(If completion of the pushing operation is
detected by the INP output, the PLC
cannot confirm the completion).
Check the INP output signal before the
energy saving mode is turned on.
-> 6.3 Parallel I/O signals
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
matches with the actuator product number.
Check that the power supply 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 input
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.
-> 8.7 Controller input signal response time
SVON time
Check that the Operation was sent after
SVON input is ON and SVRE output is
ON.
When the power is supplied, it may take up
to 20 seconds from servo ON to SVRE ON
depending on the actuator position or
conditions. Send an operation only when the
SVRE output is ON.
