1–3Installing and Wiring Your ControlNet Adapter Board
Publication 1336 FORCE–5.18 ––March, 1999
To select your input voltage, you need to set the discrete I/O
jumpers.
!
ATTENTION: To avoid damaging the CNA Board,
you must set all discrete I/O jumpers to the same input
voltage applied to the ControlNet Adapter Board. The
voltage must be either 24V DC or 120V AC.
Set this discrete
I/O jumper:
To set this input: To either:
DR EN Drive Enable 24V dc or 120V ac
M THERM Motor Thermoguard 24V dc or 120V ac
N STOP Normal Stop 24V dc or 120V ac
X FLT External Fault 24V dc or 120V ac
You can use jumper J3 on the ControlNet Adapter Board to either
allow (enable) or not allow (disable) writes to Battery backed
Random Access Memory (BRAM).
Choose:
To:
EN (Enabled) Allow writes to BRAM.
DIS (Disabled) Not allow writes to BRAM.
Two terminal blocks, TB20 and TB21, are provided at the bottom of
the ControlNet Adapter Board for discrete and analog I/O wiring.
To make the connections more easily, you can pull apart the terminal
blocks when connecting the cables.
Both terminal blocks accept a maximum wire size of 3.3 mm
2
(12
AWG) and a minimum wire size of 0.60 mm
2
(30 AWG). Maximum
torque is 0.79 N–m (7 lb–in). Recommended control signal wire is:
