Inverter Overheat Alarm (Setting : 11)
•
When the inverter detects a overheat signal “ON”, the digital operator will
change its display as “Overheat Alarm”. And the inverter still maintains its
operation. When the overheat signal is “OFF”, the digital operator will restore its
previous display automatically. No RESET-key pressing is required.
•
FJOG Command (Setting : 12)
•
RJOG Command (Setting : 13)
•
The jogging can be performed in forward or reverse rotation.
Setting = 12:FJOG command “ON”: Run forward at the jog frequency (An-17).
= 13:RJOG command “ON”: Run reverse at the jog frequency (An-17).
•
The forward jog and reverse jog commands have priority over other frequency
command commands.
•
The inverter will stop running with the stopping method set by the setting of Sn-
06 if the forward jog and reverse jog commands are both ON for more than 500
ms.
•
PID Integral Reset (Setting : 14)
•
In the application of PID control, the integral can be reset to zero (ground)
through the multi-function input terminal
g
~
j
(Sn-25
～
28= 14).
•
PID Control Invalid (Setting : 15)
OFF PID control valid (close-loop)
ON PID control invalid (open-loop)
•
This setting can be used in the changeover of test run. To disable the PID function
(PID control invalid is “ON”)
，
an open-loop operation or jog operation can be
performed in the test. The system can be set up properly after some test runs.
Then, the system can be changed into PID control mode. Moreover, if the
feedback signal is not usable, the PID function is disabled through this setting.
•
The setting of Sn-64 can be used to enable or disable the PID function.
•
External Fault Contact A (Setting : 16)
•
External Fault Contact B (Setting : 17)
•
The external fault input terminal is set to “ON”, an external fault then occurs. If
the external input terminal
h
is set for the external fault input terminal use, a
message of “Fault Ext. Fault 6” will be displayed.
•
There are 5 terminal to be assigned as external fault inputs, they are terminal
e
,
g
,
h
,
i
,
j
•
When an external fault occurs, the inverter will be blocked from output and the
motor will coast to stop.
