The ST600 Series VFD carries two groups of relay output terminals, one open collector Y output
terminal and one high-speed pulse output (HDO) terminal. The function of all the digital output
terminals can be programmed by function codes, of which the high-speed pulse output terminal HDO
can also be set to high-speed pulse output or digital output by function code.

The table below lists the options for the above four function parameters, and users are allowed to
select the same output terminal functions repetitively.
Output terminal has no function
Output ON signal when there is frequency output
during running
Output ON signal when there is frequency output
during forward running
Output ON signal when there is frequency output
during reverse running
Output ON signal when there is frequency output
during jogging
Output ON signal when VFD fault occurred
Frequency level detection FDT1
Refer to P08.32 and P08.33
Frequency level detection FDT2
Refer to P08.34 and P08.35
Output ON signal when the VFD output frequency
and reference frequency are both zero.
