Command input from an external ter-
minal or other source.
–
Check that a Run Command is not
being input from an external termi-
nal or other source.

SI-T WDT
Err
SI-T Watchdog Error Detected
A Watchdog error was detected when
the Run Command or a frequency ref-
erence was set from an option board
and continuous operation was set for
the E5 operation selection.
Synchronization error between master
controller and Inverter for control
data.
Check the communications timing
such as communications cycle.

SI-T
Address
Err
SI-T Station Number Setting Error

Command
An external baseblock signal was
input from a multi-function input ter-
minal, and the Inverter output was
shut down.
An external baseblock signal was
input from a multi-function input ter-
minal.
Check the external sequence.
HCA
(blinking)
High Cur-
rent Alarm
Current Alarm
The output current has exceeded the
overcurrent alarm level (over 150% of
the rated current).
The load is too heavy or the accel/
decel time is too short.
Increase the acceleration/decelera-
tion time.
Either a specialized motor or an
excessively large motor is being used.
Verify the setting for the Inverter
capacity.
The current has risen too high while
performing speed search either during
a momentary loss in power or during
a fault restart.
Momentary losses in power or fault
restarts may occasionally trigger an
overcurrent alarm, and are not nec-
essarily indicators of an overcurrent
problem.
