•
With this setting, the multi-function input resets faults that have occurred.
•
When a fault has occurred, be sure to find out what kind of fault occurred, take steps to correct the
cause of the fault, and restart the Inverter. It is possible to damage the Inverter by repeatedly resetting
a fault without correcting the cause.
•
To resume operation after a fault has occurred, turn the run command OFF, turn the fault reset input
from ON to OFF, and then turn the run command ON again. A fault cannot be reset while the run com-
mand is ON.
•
If a fault hasn’t occurred, turning the fault reset ON and OFF will have no effect on operation.
D
PID Disable (Setting: 19)
OFF
Enables PID control.
ON
Disables PID control. (Normal Inverter control)
•
With this setting, the multi-function input switches between PID control and normal Inverter control.
•
This function can be used to perform trial operation or jog operation with normal inverter control (open-
loop control) and then switch to PID control (closed-loop control using feedback) after adjusting the
system. The PID disable function can also be used to switch to open-loop control when there is a prob-
lem with the feedback value.
D
Program Lockout (Setting: 1B)
OFF
Write-protects all parameters except for frequency monitor.
ON
Allows parameters specified in Initialize mode to be changed.
•
With this setting, the multi-function input can be used to write-protect the Operator’s parameters.
•
When the input is OFF, the Operation mode’s frequency can be monitored and the frequency can be
changed but other changes are prohibited.
D
Trim Control Increase and Decrease (Settings: 1C and 1D)
Trim Control
Increase
Trim Control
Decrease
Output frequency
ON
OFF
Reference fre trim control level (d4-02)
OFF
ON
Reference frequency – trim control level (d4-02)
ON
ON
Reference frequency
OFF
OFF
Reference frequency
•
The trim control increase function adds the level in d4-02 to the analog frequency reference and the
trim control decrease function subtracts the level in d4-02 to the analog frequency reference.
•
These functions are effective when the frequency reference is input from an analog input.
•
These functions can be used independently or together.
•
The analog frequency reference won’t be changed when both the trim control increase and decrease
inputs are ON.
•
The output frequency is limited to zero when the trim control decrease input is ON and the result of the
subtraction is less than zero.
Note Select and set one of the following functions for multi-function input. Do not set more than one of
them, otherwise a setting error (OPE3) will result.
