6. Connect Inputs and Outputs
This section describes how to connect inputs and outputs to the TQ10X.
CAUTION
I/O is not OPTO isolated. For greater noise immunity, we recommend the use of optical
isolation modules. For added noise immunity, this controller has a digital filter; each input
must be true for three successive clock cycles before recognizing a given state.
Enable Input
To enable the drive, you must connect the enable input to ground. If you break the
connection to ground while the drive is on, the TQ10X’s fault circuitry will acti-
vate, with the following results:
•
The drive will shut down power output to the motor.
•
The motor will freewheel (it may not stop immediately).
•
The bicolor LED labeled
GRN = POWER ON
,
RED = NOT ENABLED
will
be illuminated red.
•
The fault output will become active (no current will flow through it).
To re-enable the drive, establish the connection between enable and ground, and
cycle power.
In most applications, you can permanently wire the enable input to ground. This
input is internally pulled up to +5V. If your equipment requires, you can connect
the input to an external voltage as high as +24V. You can also connect it to a dry
contact closure to ground.
If you need to disable the drive in an emergency, use the enable input. Connect a
manual disable switch to the enable input, as the next drawing shows. The switch
is normally closed. When it is opened, the drive will be disabled. The load can
freewheel—therefore, you should use a brake to stop the motor immediately in
applications where a freewheeling motor can cause injury or damage.

WARNING
Do not use the ENABLE INPUT by itself as an emergency stop. The motor can freewheel
when the drive is disabled and may not stop immediately. Use a mechanical brake or some
other method to stop the motor quickly.
