Local/Remote Reference And Sequence Selection - YASKAWA V7 Technical Manual

5.13 LOCAL/REMOTE REFERENCE & SEQUENCE SELECTION
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 (n007). The
frequency reference can come from a digital preset reference (n024 & n009) or the
digital operator pot (n008).
Remote - Run and stop functions are determined by parameter n003. The frequency reference is
determined by parameter n004.
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 5.18A).

2 Run and stop is controlled by serial communications
n004 : Reference Selection
SETTING DESCRIPTION
0 Frequency reference is controlled by the digital operator potentiometer.
1 Frequency reference is controlled by a digital preset speed (n024) and is affected by n009.
2 Frequency reference is controlled by the analog input terminal FR and is 0 - 10V DC
3 Frequency reference is controlled by the analog input terminals FR and is 4 - 20mA
4 Frequency reference is controlled by the analog input terminal FR and is 0 - 20mA
