Reset Input
When active, the Reset Input forces the drive into a reset state. Power is removed from the motor and the
Fault Output is active while the drive is in its reset state. The drive will start to re-initialize itself when the
input is released. Initialization will take up to 325 milliseconds. Power is restored to the motor and the Fault
Output becomes inactive once the drive re-initializes correctly.
The Reset Input differs from the Disable Input in that the Disable Input only removes power from the motor.
The Disable Input does not re-initialize the drive. Activating the Reset Input is equivalent to cycling power to
the SD17063. The drive goes through its self test and updates the state of all latched switch settings.
The Reset Input circuit is identical to the Directional Pulse Inputs. The Reset Input can be wired as a differ-
ential, sinking, or sourcing input. Wiring schematics are included in the Wiring Directional Pulse Inputs
section, starting on page 34.
DO NOT activate the Reset Input while the motor is running. When the Reset Input is
active, there is no current to the motor and the motor is free to rotate.
Fault Output
The Fault Output is an opto-isolated 30Vdc output that is capable of driving a typical PLC input or equivalent.
Both ends of the output are floating. Therefore, it can be wired as a sinking or sourcing output. Its active, or
Fault state is off, meaning that the output will not conduct when the SD17063 is disabled, initializing, or a
problem exists with the drive. The Fault Output’s inactive, or OK state is on when the drive is operational.
The output will turn off when power is removed. Therefore, a loss of power to the SD17063 will appear as an
error condition.
There is a total of seven faults, called Major Faults, that trigger the Fault Output. The Detectable Faults and
Errors section of this chapter, starting on page 14, describes these faults and how the Fault Output behaves
during each of them.
