SD17063 Settings Overview (continued)
Self Test
This feature allows you to verify motor wiring and drive operation without an indexer. When the drive is set
for self test, the drive rotates the motor counter-clockwise at 60 RPM with a resolution of 50,000 steps per
turn.
Indexer I/O
Figure 2.1 shows the I/O connector on the
SD17063. The inputs are typically connected to
an indexer, but the Reset and Disable input are
sometimes connected to push buttons. The Fault
Output is sometimes used to drive a solid state
relay that powers a warning light instead of driv-
ing a fault input on the indexer.
All inputs are opto-coupled 5Vdc differential. The
Fault Output is an isolated 30Vdc uncommitted
open collector/emitter that can be wired as either a
sinking or sourcing output.
Directional Pulse Inputs
Directional pulses from your indexer control the motor’s position, speed, and direction of rotation. The two
Directional Pulse Inputs on the SD17063 are opto-isolated and designed for 5Vdc differential signals. They
can also be used as either sinking or sourcing single ended inputs by connecting one side to your power sup-
ply and driving the other side. Wiring schematics are given in the Wiring Directional Pulse Inputs section,
starting on page 34.
A current limiting resistor must be used for voltages greater than 5Vdc. The next section,
Indexer I/O Specifications, lists appropriate resistor values. The resistor values are also given
in the Single Ended Input Connections figure on page 35.
Disable Input
The Disable Input shuts off the motor current when it is active. Once the Disable Input is released, the motor
current ramps up to its last value instead of being applied instantaneously. Ramp up time is a maximum of
275 milliseconds. The Fault Output is active while the Disable Input is active and during the current ramp up.
Like the Directional Pulse Inputs, the Disable Input can be wired as a differential, sinking, or sourcing input.
Wiring schematics are included in the Wiring Directional Pulse Inputs section, starting on page 34.
DO NOT activate the Disable Input while the motor is running. When the Disable
Input is active, there is no current to the motor and the motor is free to rotate.
The SD17063 does not accept directional pulses when the Disable Input is active. Therefore,
when the Disable Input is turned off, the drive restores current to the motor in the same phase
relationship that existed before the Disable Input was turned on. If the motor turned while the
Disable Input was active, (which is possible, because there is no holding torque), the motor
may not re-start correctly.
