NOTE
• The protective function [E.OP1 (fault data: HA1)] is activated at error occurrences on the communication line. The
protective function [E.1 (fault data: HF1)] is activated at error occurrences in the communication circuit inside the
option.
• Fault output indicates the fault (ALM) signal and fault bit output.
• When the fault output setting is active, fault records are stored in the fault history. (A fault record is written to the fault
history at a fault output.)
• When the fault output setting is not active, fault record is overwritten to the fault history temporarily but not stored.
After the error is removed, the fault indication is reset, changing the display back to normal, and the last fault is
displayed in the fault history.
• When Pr.502 is set to "1 to 4", the normal deceleration time setting (such as Pr.8/Pr.44/Pr.45 setting) is applied.
• When a communication line error occurs while Pr.502 = "2 or 12", the motor re-accelerates if the error is removed
during deceleration. The operation command and the speed command before the fault occurred will be applied for
restarting. The normal acceleration time setting (such as Pr.7/Pr.44 setting) is applied for restart. (Acceleration is not
restarted if the error is that of the option unit itself.)
CAUTION
 When Pr.502 = "3" and a communication line error occurs, or Pr.502 = "4" and a communication line error or a communication
option fault occurs, the operation continues. When setting "3 or 4" in Pr.502, provide a safety stop countermeasure other than
via communication. For example, input a signal through an external terminal (RES, MRS, or X92) or press the PU stop on the
operation panel.
