IAI RCP2 Series User Manual

103
Code Error name Cause/Action
ED Absolute encoder error
(1)
Cause: (1) The battery voltage was 4.4 V or below when the power
was input.
(2) The current position has changed due to the effect of
vibration, etc., when the power was input.
Action: Reset the alarm.
If code “7A” is displayed after the reset, the battery voltage is
low. Charge the batteries for at least 48 hours.
If “7A” is not displayed, turn off the power, and then turn it on
again by making sure the actuator does not vibrate.
EE Absolute encoder error
(2)
The absolute counter data in the FPGA is damaged.
Cause: (1) The power was input for the first time after connecting the
batteries. (This message is always displayed at the initial
power on.)
(2) The parameter for home return direction or home return
offset was changed.
(3) The power supply was cut off for a prolonged period and
the battery voltage has dropped to a level at which the
absolute counter data can no longer be retained.
(4) The actuator was moved by hand and the followable
speed was exceeded while the power supply was cut off.
(5) The encoder cable or battery cable became open while
the power supply was cut off.
Action: Check the cables for loose connections.
Reset the alarm. Then, execute home return after confirming
that the *ALM signal has turned ON again.
If the battery voltage is low, supply the power for at least 48
hours.
EF Absolute encoder error
(3)
Cause: The actuator was moved by hand and the motor speed
exceeded 150 rpm while the power supply was cut off.
Action: Reset the alarm. Then, execute home return after confirming
that the *ALM signal has turned ON again.
Be careful not to move the actuator while the power supply is
cut off.
F7 EEPROM write error A current-position write signal (PWRT) was input in the teaching mode
when the controller was unable to receive the signal.
Cause: (1) The signal was input when home return was not yet
completed.
(2) The signal was input during jogging.
Action: (1) Input the signal after confirming that home return has
completed (HEND is ON).
(2) Input the signal after confirming that the JOG button is not
pressed or the actuator is stopped (MOVE is OFF).
