LCD display, the LED display text will be shown in parentheses under the LCD display text.
Alarm Codes, Causes, and Possible Solutions
u
Alarms are drive protection functions that do not necessarily cause the drive to stop. After removing the cause of an alarm,
the drive will return to its previous status before the alarm occurred.
When an alarm has been triggered, the ALM light on the digital operator display blinks and the alarm code display flashes. If
a multi-function output is set for an alarm (H2-oo = 10), that output terminal will be triggered.
Note: If a multi-function output is set to close when an alarm occurs (H2-oo = 10), it will also close when maintenance periods are reached,
triggering alarms LT-1 through LT-4 (triggered only if H2-oo = 2F).

Station Address Setting Error (CC-Link, CANopen, MECHATROLINK)
AEr
Option card node address is outside the acceptable setting range.
• Set parameter F6-10 to the proper value if a CC-Link option card is used
• Set parameter F6-20 to the proper value if a MECHATROLINK option card is used.
• Set parameter F6-35 to the proper value if a CANopen option card is used.
Analog Feedback Lost
Analog feedback has not been detected and the network PID feedback signal is now used.
Confirm that the PID feedback source is installed and working properly. If there is no feedback source,
set P9-02 to 3 so the drive will read the network PID feedback from another drive.
Set H3-0o to B if the analog input source is to be used for PID feedback.
Set P9-02 to 3 if the drive does not have an analog PID feedback source.
• Alarm will clear when function is complete.
• Drive response to this condition is controlled by P7-01, Anti-jam Operation Selection.
Digital Operator Battery Voltage Low
bAT
Replace the digital operator battery.
Baseblock
bb
Drive output interrupted as indicated by an external baseblock signal.
Check external sequence and baseblock signal input timing.
Option Communication Error
• The connection was lost after initial communication was established.
