Step division option
The driver allows to divide electronically physical stepper motor step
– 2, 4, 8, 16. Thus positioning accuracy is higher. Step division mode
is called microstep division. This mode allows to reduce stepper motor
resonances at low revs. It is recommended to use PLD442 driver in
step division 1:8 and higher. In these modes stepper motor rotates as
smooth as possible, low-frequency vibrations are minimal.
Switching step division mode is carried out by jumper mounting to
М1, М2 and М3 contacts of XP8 connector (fig. 6).
Power off device before making any connections.
