3.7.4 Wiring PG Speed Control Card Terminal Blocks
Use no more than 100 meters of wiring for PG (encoder) signal lines, and keep them separate from power
lines.
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield
to the shield connection terminal.

Solderless Terminals for Control Circuit Terminals
The use of solderless terminals for the control circuit terminals is recommended because solderless termi-
nals are easy to connect securely.

Do not solder wires with the control circuit terminals if wires are used instead of solderless terminals.
Wires may not contact well with the control circuit terminals or the wires may be disconnected from the con-
trol circuit terminals due to oscillation if the wires are soldered.
