Input Interface Description
The M335 can accept differential and single-ended inputs (including open-collector and PNP
output). The M335 has 3 optically isolated logic inputs which are located on connector P1 to
accept line driver control signals. These inputs are isolated to minimize or eliminate electrical
noises coupled onto the drive control signals. We recommend to use line driver control signals to
increase noise immunity of the driver in interference environments. In the following figures,
connections to open-collector and PNP signals are illustrated.
DIR-
PUL signal by 5μs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW.
Please note that motion direction is also related to motor-driver wiring match.
Exchanging the connection of two wires for a coil to the driver will reverse
motion direction.

the contrary, namely Low level for enabling.) for enabling the driver and low
level for disabling the driver. Usually left UNCONNECTED (ENABLED)
