Terminal block TB20 provides the discrete I/O capabilities.
Discrete Outputs
Fault outputs from the 1336 FORCE are supplied at terminal block
TB20 on the ControlNet Adapter Board. Fault outputs provide
warning or fault signals based on drive status.
The Fault NC, Fault Com, and Fault NO outputs are relay contacts
that provide fault signals. If a contact is closed (energized), then
there is no fault. If a contact is open, there is a fault.
The following values are the contact ratings for the Fault NC, Fault
Com, and Fault NO relays:
2A at 115V AC
2A at 30V DC
The typical digital output connections can be shown as follows:
FAULT N.O. (DIGITAL OUT)
FAULT COM (DIGITAL OUT)
FAULT N.C. (DIGITAL OUT)

Discrete Inputs
Discrete inputs to the 1336 FORCE are supplied through the
ControlNet Adapter Board at terminal block TB20. Discrete inputs
enable and stop the drive as well as providing checks on drive and
motor operation.
The typical digital input connections when using an external power
source can be shown as follows:
INPUT COM (DIGITAL COMMON)
NORM STOP (DIGITAL IN)
EXT FAULT (DIGITAL IN)
MOTOR THERMO (DIGITAL IN)
DRIVE ENABLE (DIGITAL IN)
