Precautions
•
Jog
frequencies using FJOG and RJOG commands are given priority over other frequency references.
•
When
both FJOG command and RJOG commands are ON for 500 ms or longer at the same time, the
Inverter
stops according to the setting in b1-03 (stopping method selection).

Errors
to
the
Inverter
(External
Error
Function)
The
external error function performs the error contact output, and stops the Inverter operation if the Inverter
peripheral
devices break down or an error occurs. The digital operator will display EFx (External error [input
terminal
Sx]). The x in EFx shows the terminal number of the terminal that input the external error signal. For
example,
if an external error signal is input to terminal S3, EF3 will be displayed.
To
use the external error function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05
(multi-function
contact input terminal S3 to S7 function selection).
Select
the value to be set in H1-01 to H1-05 from a combination of any of the following three conditions.

Operation
during external error detection
The
following table shows the relationship between the combinations of conditions and the set value in H1-
oo
.
Note1.Set
the input level to detect errors using either signal ON or signal OFF. (NO contact: External error when ON; NC contact: External error when OFF).
2. Set
the detection method to detect errors using either constant detection or detection during operation.
Constant
detection: Detects while power is supplied to the Inverter.
Detection
during operation: Detects only during Inverter operation.
