Startup Frequency

Startup Frequency
Program Special Controls
The output of the ASD will remain at 0.0 Hz until the programmed speed value
exceeds this setting during startup. Once exceeded during startup, the output
frequency of the ASD will accelerate to the programmed setting.
Output frequencies below the Startup Frequency will not be output from the
ASD during startup. However, once reaching the Startup Frequency, speed
values below the Startup Frequency may be output from the ASD.

ST Terminal Delay

Program Terminal Delays
This parameter delays the response of the ASD to any change in the ST
terminal input by the programmed value (see waveforms at
The delay may be increased to provide additional electrical noise immunity or
to prevent the ASD from responding to contact bounce or chatter.

ST Terminal

Program Input Terminals
This parameter selects the functionality of the ST discrete input terminal.
In addition, the input terminal must be specified as Normally Open or
Normally Closed.
This parameter sets the programmable ST terminal to 1 of the 69 possible
functions that are listed in
