Phase Det ALM
(1-193)
E
Power off
<Contents>
Unable to find the motor phase within the set time.
(When the servo motor is turned on (SVON is turned ON) first
time after the power is applied, the electric actuator needs to
move a little to find the motor phase. However, if this electric
actuator movement is prevented, this alarm will be activated.)
<Countermeasure>
Make sure there are no obstructions that
interfere with the electric actuator movement and then, turn on
the servo motor (SVON is turned on).
Over current
(1-194)
E
Power off
<Contents>
The output current of the power circuit is extraordinarily high.
<Countermeasure>
Make sure that there are no short circuits of actuator cables,
connectors, etc. In addition, make sure that the electric actuator
conforms to the controller.
I sens ALM
(1-195)
E
Power off
<Contents>
An abnormality is detected by the current sensor that is checked
when the controller is reset.
<Countermeasure>
Make sure that the electric actuator conforms to the controller.
When a command to turn on servo is given, check if BK RLS is
energized by installing the electric actuator vertically in order to
check if the motor is driven by an external force.
Even after this measure, if the alarm regenerates when the power
is reapplied, please contact SMC.
Err overflow
(1-196)
E
Power off
<Contents>
An overflow of the position error counter inside of the controller is
occurred.
<Countermeasure>
Make sure there are no obstructions that interfere with the
electric actuator movement. Also, make sure that the load,
speed, acceleration and deceleration are within the range of the
electric actuators.
Memory ALM
(1-197)
E
Power off
<Contents>
An error of the EEPROM is occurred.
<Countermeasure>
Please contact SMC.
(The write limit of the EEPROM is roughly 100,000 times)
CPU ALM
(1-198)
E
Power off
<Contents>
The CPU is not operating normally.
(It is possible that the CPU or surrounding circuits is failed or a
malfunction of the CPU is occurred due to an electric noise).
<Countermeasure>
If the alarm cannot be deactivated even after the power is
reapplied, please contact SMC.
CC-Link
Communication
error
(01-206)
E
control
power
supply off
<Contents>
This alarm is generated when a CC-Link communication error
has occurred and the WDT (Watch Dog Timer) in the controller
has reached the time limit.
<Countermeasure>
Please contact SMC when this alarm is generated.
*1) When an alarm for the remote register (RWr) is generated, only the portion of "
" in the code
"01-
" is output.
Please refer to
"10.1.2 Remote register (RWr and RWw)"
for details on the remote register.
