Step, Direction and Enable Inputs
Step Input
J4 1, 2
The P70360 increments its internal step counter on the ON-to-
OFF transition of the LED in an opto isolator. Minimum ON and
minimum OFF times are both 250 ns. This results in a maximum
step input frequency of 2 MHz. Pulses that do not meet minimum
times may be ignored by the drive's electronics.
The input
circuitry is suitable for use with 5-volt logic (single ended or
differential). It is best to drive the input to both logic states
rather than utilize open collector transistors
The STEP input is sensitive to high frequency noise and
should be supplied through shielded cable.
