4.5.2 Wiring Requirement:
1. Encoder card wire should be laid separately and keep distance from power cables and forbidden to
parallel with them.
2. Encoder card wire should be installed inside separated metal conduits and connected to ground
firmly.
4.5.3
FD Description
To change the FD coefficient, shift 6-digit FD switches. When the switch shifts to ON, it means “1”,
otherwise means “0”. Convert the 6-digit binary number into decimal number. Multiple the decimal
number by 2, the result is FD coefficient, as shown in Figure 4-15.
Maximum value is “111111” which is 63*2 FD.
