WARNING!
It is not the design intent of the +5VDC
output to supply power to external loads! This voltage
output is only to be used to supply voltage to the
internal circuitry of the OSC-462H/IB462H assembly
and the speed control input!
NOTE:
The physical direction of the motor with respect to
the direction input will depend upon the connection of the
motor windings.
NOTE:
The Stop/Start input must be in the stopped position
(logic HIGH) in order to use an external step clock to index
the motor.
S t e p C l o c k ( P i n 1 1 )
The Step Clock input is internally pulled-up to +5VDC through a 4.99k
Ω
resistor. This input would be used if an external 0 - 40kHz clock input is being
used as a motion clock for the IB462H. This input will increment the motor
only
if the /Start input is in a logic HIGH (internal oscillator stopped) state.
The Direction input will function normally.
D i r e c t i o n ( P i n - 1 2 )
The CW/CCW direction input is internally pulled-up to +5VDC through a
4.99k
Ω
resistor.
This input may be connected by means of a switch between the input (Pin 12)
and logic ground (Pin 8) or a sinking output.
/ S t a r t ( P i n 1 3 )
The Stop/Start input is internally pulled-up to +5VDC through a 4.99k
Ω
resistor. When in a logic HIGH, or disconnected, state the internal step clock
generator will be off. Connecting this input to logic ground (pin 8) or a sinking
output in a LOW state will enable the internal step clock oscillator.
This input may be controlled by means of a switch between the input (pin 13)
and logic ground (pin 8) or a sinking output.

The +5VDC output is to be connected to the signal end of the 10k

D i r e c t i o n O u t p u t ( P i n 1 4 )
The Direction output is buffered through an open-drain N-channel FET. This
output will follow the direction input.
