3.5 REMOTE VOLTAGE PROGRAMMING
Remote voltage programming configuration is used for applications that
require the output voltage be programmed (controlled) from a remote
source. An external 4-20mA current source or external voltage source
may be used as a programming device. When using remote voltage
programming, a shielded, twisted-pair, hookup wire is recommended to
prevent noise interference with programming signals.
3.5.1 EXTERNAL VOLTAGE PROGRAMMING USING A 4-20MA CURRENT
SOURCE
The current source coefficient for remote voltage programming is
16mA/100% of rated output voltage with respect AGND (terminal 9 on
digital option board, terminal 20 on SG compatible option board, or
terminal 5 on EtherCAT Option Board). The programming current from
terminal V_PROG (terminal 12 on digital option board, terminal 15 on SG
compatible option board, or terminal 9 on EtherCAT Option Board) should
be a 4-20mA current source. This yields a coefficient of 1.0% of rated
output voltage for each 0.16mA.
See Figure 3-9 to Figure 3-11 for connection requirements.
