Earth Fault Trip Time
Program Special Earth Fault
In the event that the Earth Fault Trip activation criteria is met, a timer begins
to count down to zero. Upon reaching zero, the Earth Fault Trip is activated.
This parameter sets the start-time of the count-down timer.
Acceleration/Deceleration Frequency Adjustment
Program Terminal Analog Input Functions
This parameter Enables/Disables the feature that allows for the external
adjustment of the Base Frequency. When enabled, either VI/II or RR may be
used as an input source for the modification of the Base Frequency setting.
Settings:
0 — Disabled
1 — VI/II
2 — RR
Upper-Limit Frequency Adjustment
Program Terminal Analog Input Functions
This parameter Enables/Disables the feature that allows for the external
adjustment of the Upper-Limit. When enabled, either VI/II or RR may be used
as an input source for the modification of the Upper-Limit setting.
Settings:
0 — Disabled
1 — VI/II
2 — RR
Acceleration Time Adjustment
Program Terminal Analog Input Functions
This parameter Enables/Disables the feature that allows for the external
adjustment of the Acceleration Time. Selecting either VI/II or RR enables this
feature. The selected input is used as a multiplier of the programmed
Acceleration Time setting. The multiplication factor may be from 1 to 10.
Note: An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Settings:
0 — Disabled
1 — VI/II
2 — RR
