Output Management
Introduction
The LT includes Standard outputs and fast outputs.
The following output functions are configurab
le on fast outputs:
z PWM Output
z Pulse Output
z High-speed Counter (Synchronize Output)
Fast Output Management Availability
The information refers to a
ll LT wi
th fast outputs:
Short-circuit or Over-Current on Outputs
There are two groups for th
e output'
s short circuit and over-current.
Group 1 (Fast Output) has a shor
t-circuit protection circuit between the output and
V-. Group 2 (Standard Output) does not have this circuit.
LT-4201TM (Modular Type DIO) and LT-4301TM (Modul
ar Type DIO)
z Group 1: 2 points Fast Output (Q0 to Q1)
z Group 2: 10 points Standard Output (Q2 to Q11)
LT-4201TM (Modular Type Analog) and L
T-4301TM (Modular Type Analog)
- Group 1: 2 points Fast Output (Q0 to Q1)
- Group 2: 6 points Standard Output (Q2 to Q7)
Th
e table describes the errors:
For more information on protecting outputs, refer to your controller wiring diagram
and to the general wiring rules (see page 33).
The Standard outputs of this equipment do not have built-in reverse pol
arity
protection. Incorrectly connecting polarity can permanently damage the output
circuits or otherwise result in unintended operation of the equipment.

If... then...
you have a short-circuit at 0 V on Fast Output Fast Output is stopped and error message is
generated. For more
details, refer to the GP-
Pro EX Reference Manual.
you have a short-circuit at 24 V on Fast
Output
