3.4.2 REMOTE CURRENT PROGRAMMING USING A 0-10 VDC VOLTAGE
SOURCE
A DC voltage source for remote current programming is connected
between I_PROG (terminal 11 on digital option board, terminal 16 on SG
compatible option board, or terminal 4 on EtherCAT Option Board) and the
return terminal AGND (terminal 9 on digital option board, terminal 20 on
SG compatible option board, or terminal 5 on EtherCAT Option Board).
The voltage coefficient for 10V remote current programming is 100
millivolts = 1% of rated output, i.e., for a 500 amp model, each 100
millivolts of programming voltage equals 5 amps of output current. See
Figure 3-6 to Figure 3-8 for connection requirements.
