Controlling signals connection to stepper motor driver
Controlling signals connection
PLD442 driver controls a stepper motor using standard signals
STEP/DIR/ENABLE.
STEP/DIR/ENABLE signals are allocated to connectors XP2, XP3,
XP4 and RJ45 — XP5-type and are galvanically separated from the
controller.
As STEP signal frequency is increased, LED4 intensity also changes.
The scheme of differential input device and connection method to
the controller with outputs ‘open collector’ type is shown in fig.2.
STEP signal characteristics are working voltage 3 ... 5V, current
consumption is 20mА, min signal duration is 10 ms. Stepper motor step
is performed on signal’s back edge.
DIR signal’s characteristics – working voltage 3 ... 5V, current
consumption is 20mА, action time is 200 ns before/after STEP’s front
edge.
