INVERTER SETTING
 Operation at error removal
Error Definition
Communication line
Communication
option itself
CAUTION
• Communication line error [E.OP1 (fault data: HA1)] is an error that occurs on the communication line.
Communication option itself error [E. 1 (fault data: HF1)] is an error that occurs in the communication circuit
inside the option.
• Fault output indicates the fault signal (ALM signal) output and fault bit output.
• When the fault output setting is active, fault records are stored in the faults history.
When the fault output setting is not active, fault record is overwritten to the faults history temporarily but
not stored.
After the fault 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 normal deceleration time setting (e.g. Pr. 8,
Pr. 44, Pr. 45).
• The acceleration time at a restart is the normal 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 fault
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.)
