1. All functions on terminals 18 and 19 are controlled
by an interrupter, which means that the repetitive ac-
curacy of the response time is constant. Can be used
for start/stop, set-up switch, and especially for chang-
ing digital preset, i.e., to obtain a reproducible stop
point when using creep speed. For further information,
see VLT 2800 Precise Stop Instruction, MI.28.CX.02.
Function:
In these parameters, 302-307 Digital inputs, it is pos-
sible to choose between the different enabled func-
tions related to the digital inputs (terminals 18-33).
