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