3-4 Operation
The Strobe Out is a square wave. Its falling edge is centered between
the consecutive rising edges of the Index Pulse.

Ext Line Speed In
This is an analog input requiring a DC voltage within the range of
-10V > Vin > +10V. You can set the commanded speed from an analog
voltage within this range. Within the selected range, the motor speed
is directly proportional to input voltage.
In Unidirectional mode, zero speed occurs at 0V input voltage and
maximum speed occurs at +10V DC input voltage. The direction of
rotation in this mode is set by the Options switch.
In Bi-directional mode, zero speed occurs at 0V DC input voltage.
Maximum reverse speed occurs at -10V DC input voltage and
maximum forward speed occurs at +10V DC input voltage.
When the ESRS is set to EXT, the LINE SPEED control has no function.
The input resistance of this input is 100k
Ω
. Therefore the output
resistance of the device driving this input should be 1k
Ω
or less to
avoid interface errors.
Input clamping at ±15V is provided at this input. The input current is
not limited by the ESRS when clamping occurs.
Acceleration and rounding are operational in this mode.
P1
The P1 connector is a 2 part 6 way mating screw that lets you make
the connection to the Enable Voltage Input and Output and the
Direction Output.
