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, 2", 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", 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 = "6", operation continues even if a communication line error or a fault of the communication option occurs. When setting "6" 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.
