Output Management
Introduction
The LT Unit includes Standard outputs and fast outputs.
The following output functions are configurable on fast outputs:
 PWM output
 Pulse output
 High-speed Counter (Synchronize Output)
Fast Output Management Availability
The information refers to all LT with fast outputs:
Short-circuit or Over-Current on Outputs
There are two groups for the output’s short circuit and over-current.
Group 1 (Fast Output) has a short-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 (Modular Type DIO):
 Group 1: 2 points Fast Outputs (Q0 to Q1)
 Group 2: 10 points Standard Outputs (Q2 to Q11)
LT-4201TM (Modular Type Analog) and LT-4301TM (Modular Type Analog):

Group 1: 2 points Fast Outputs (Q0 to Q1)
 Group 2: 6 points Standard Outputs (Q2 to Q7)
The table describes the errors:
For more information on protecting outputs, refer to your controller wiring diagram and to the
general wiring rules (see page 32).
The Standard outputs of this equipment do not have built-in reverse polarity protection. Incorrectly
connecting polarity can permanently damage the output circuits or otherwise result in unintended
operation of the equipment.
Output Terminal Function
Q0 Pulse Output/CH 0, PWM Output/CH 0,
High-speed Counter (Synchronize Output)/CH 0
Q1 Pulse Output/CH 1, PWM Output/CH 1
High-speed Counter (Synchronize Output)/CH 1
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
the current crossing the Fast Output is too high
NOTICE
DAMAGE TO FAST OUTPUTS
 Ensure the use of adequate protection against short-circuits on the power supply to the fast
outputs.
 Do not connect positive voltage to any of the DC fast outputs terminals.
Failure to follow these instructions can result in equipment damage.
