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 faults history. (A fault record is written to the
faults history at a fault output.)
When the fault output setting is not active, fault record is overwritten to the faults 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 faults history.
• When the Pr.502 setting is "1" or "2", the deceleration time is the ordinary deceleration time setting (e.g. Pr.8, Pr.44,
Pr.45).
• The acceleration time at a restart is the ordinary acceleration time setting (e.g. Pr.7, Pr.44).
• When the Pr.502 setting is "2", the operation/speed command at a restart is the one given before the error occurrence.
• When a communication line error occurs at the Pr.502 setting of "2", removing the error during deceleration causes
acceleration to restart at that point. (Acceleration is not restarted if the error is that of the option unit itself.)
• In order to continue the operation even if a communication line error occurs when Pr.502 = "3", provide a safety stop
measure other than via communication, for example by inputting a signal to the terminal RES.
