Alarm
name
Recovery
method
Content / Countermeasure
Memory error
Turn the power
off and on
again.
<Content of error> The internal memory fails.
Check if the conditions described below occurs.
(1) Power supply shut-off during data writing
(2) Power interruption of the power supply voltage
(3) Noise due to crossing of cables and power lines.
<Countermeasure> Turn off the power and then turn it on again.
Temperature
error
Turn the power
off and on
again or reset
using the
SVON input.
<Content of error> The rated temperature is exceeded due to increase in
temperature in the motor.
Check if the
conditions described below occurs.
(1) The product is used in a location where the specified ambient
temperature is exceeded.
(2) There is a heat generating source around the motor.
(3) The product is used with the force exceeding the allowable thrust setting
value.
<Countermeasure> Review the ambient temperature and check the
operation again after supplying power again or turning the SVON input
signal OFF temporarily.
Caution
Please refer to the manual or the catalogue of the actuator for
the allowable thrust setting value.
When the Card Motor is not connected to the controller,
temperature error can be generated due to unstable
temperature information.
Check the Card Motor and controller connection.
Over current
error
(Motor overload
error)
(Over current
error)
Turn the power
off and on
again or reset
using the
SVON input.
<Content of error> This alarm is generated when the Card Motor has
been overloaded causing an overcurrent to flow through the Card Motor,
and when overcurrent flows through the parallel output terminals.
Check if the conditions described below occur.
(1) The motor cannot reach the target position during positioning due to
obstacles.
(2) The connection of the output signal is not correct.
<Countermeasure> Check the motor type and rated value. Turn the
power off and on again
Check the operation again after turning the SVON input signal OFF.
Parameter
error
(Origin parameter
error)
(Step Data
parameter error)
(Invalid parameter
error)
Turn the power
off and on
again or reset
using the
SVON input.
<Content of error> The basic parameter setup and step data setup
settings are not correct. Check if any of the conditions described below
occur.
(1) Error related to the basic parameter data - [Card Motor product
number] has not been selected. (2) Error related to the step data
-
"Target Position" of the step data is set outside of the stroke range, or
the "positioning time", "speed", "acceleration" or "deceleration" is set to
0.
- It is not possible to achieve the [Target position] and [Positioning time]
using the Cycle Time Entry Method (or "Speed", "Acceleration" or
"Deceleration" using the Speed Entry Method) for the next step data from
the current table position.
<Countermeasure> Check the basic parameter data and step data.
Check the operation again after turning off and on the power supply or
turning the SVON input signal OFF.
Return to
origin position
non-execution
error
Turn the power
off and on again
or reset using the
SVON input.
<Content of error> The operation is instructed while return to origin
position has not been executed yet.
<Countermeasure> Perform the return to origin position after turning the
SVON input signal OFF.
