Disable Input Wiring (continued)
The Fault Output is active, (it will not conduct current), when the Disable Input is active and the fault output
remains active during the current ramp up time. Therefore, you can use the Fault Output to signal when the
drive is ready to accept pulses instead of timing out the 275 milliseconds. (The active state of the Fault Out-
put is off. Therefore, a loss of power appears as a fault condition.)
Reset Input Wiring
The ±Reset Input on the SD17063 resets the drive when active. The circuitry of this input is identical to the
directional pulse inputs. Refer to figures 5.3 and 5.4 when wiring this input. A momentary or SPST switch
can be used in place of the open collector output shown in figure 5.4.
After changing the Pulse Train Input, Output Waveform, or Step Resolution DIP switches, you can activate
the Reset Input to force the SD17063 to accept these changes instead of cycling power to the drive. You can
also clear Major Faults by activating this input instead of cycling power.
Do not activate the Reset Input while the motor is running. When the Reset Input is
active the current to the motor is removed and the motor is free to rotate. No holding
torque is available while the Reset Input is active.
The Fault Output is active, (it will not conduct current), when the Reset Input is active and the fault output
remains active during the 325 milliseconds after the release of the Reset Input that is needed to initialize the
drive. Therefore, you can use the Fault Output to signal when the drive is ready instead of timing out the 325
milliseconds. (The active state of the Fault Output is off. Therefore, a loss of power appears as a fault condi-
tion.) Sending pulses to the drive before this initialization time has expired will result in a Window Step Vio-
lation. See Minor Faults on page 14 for more information on the Window Step Violation fault.
Fault Output Wiring
The ±Fault Output is an opti-
cally isolated transistor capable
of driving a typical DC PLC
input or equivalent. As shown
in figure 5.5, both ends of the
output are floating. Therefore,
you can connect the fault output
in a sourcing or sinking configu-
ration.
The Fault Output conducts when
the drive is operating normally
and shuts off when the drive is
disabled by the Disable Input,
initializing due to the Reset
Input or when powering up, or
whenever a major fault occurs.
Detectable Faults and Errors,
starting on page page 14 lists the
conditions that trip the Fault
Output.

A resistor may be needed to limit
the current through the Fault
Output. The value, and power
rating of the resistor is dependent
on the value of V
DC
, the voltage
drop across the input, and the
current requirements of the input.
