The Drive has the ability to have either a local or a remote reference and sequence selection.
Local -
Run and stop functions are controlled by the buttons on the digital operator (
n06
). The
frequency reference can come from a digital preset reference (
n21
&
n08
) or the
digital operator pot (
n07
).
Remote -
Run and stop functions are determined by parameter
n02
. The frequency reference is
determined by parameter
n03
.
Switching between local and remote is accomplished either by the LO/RE LED on the digital operator
or by the use of a multi-function input terminal programmed to data “
17
” (see paragraph 5.17A).
