(2) Operation-cancellation level alarms
Code Error name Cause/Action
B0 Bank 30 data error Cause: Data in the parameter area is outside the input range or invalid.
(This alarm will not generate in normal parameter input operation, but may
occur during serial communication using the PLC’s communication
module.)
Action: Transfer data after confirming that the parameter values are valid.
B1 Bank 31 data error Cause: [1] A movement command was issued by selecting a number to which no
position data was registered.
[2] Position data value exceeds the soft limit setting.
[3] The position number was recognized wrongly due to an unstable start
signal or insufficient signal input period.
Action: [1] Revise the sequence in such a way that unregistered position
numbers will not be selected.
[2] Change the position data to a value inside the soft limit settings.
[3] The minimum timer setting may not be recognized depending on the
PLC. Pay attention to the timer setting.
BE Home return timeout Cause: Home return does not complete within the period set in the applicable
system parameter after the start of home return operation.
Action: This alarm will not generate in normal operation. Should you encounter the
alarm, please contact IAI.
C0 Excessive actual speed Cause: This alarm indicates that the motor speed exceeded the maximum speed
set in the applicable system parameter.
This alarm will not generate in normal operation, but may occur in the
following conditions:
[1] Large actuator slide resistance in certain area, or
[2] Instantaneous increase in load due to application of external force,
which may cause the load to decrease and actuator to move rapidly
before a servo error is detected.
Action: Check for abnormality in the assembly condition of mechanical parts.
If the actuator is suspected to be the cause, please contact IAI.
C1 Servo error This alarm indicates that after receiving a movement command the motor is unable
to operate for two seconds or more before reaching the target position.
Cause: [1] Brake cannot be released on a controller equipped with brake.
[2] Large load due to application of external force
[3] Large slide resistance of the actuator itself
Action: [1] Turn on/off the brake release switch to see if the brake makes “click”
sounds.
[2] Check for abnormality in the assembly condition of mechanical parts.
[3] If the load capacity is normal, cut off the power and move the
actuator by hand to check the slide resistance.
If the actuator is suspected to be the cause, please contact IAI.
C9 Excessive motor supply
voltage This alarm indicates that the motor supply voltage is excessive (24 V + 20%: 28.8
V or more).
Cause: [1] High voltage of the 24-V input power supply
[2] Faulty controller board component
Action: Check the voltage of the input power supply.
If the voltage is normal, please contact IAI.
