3. Pin Assignment and Description
The DM860I has two connectors, connector P1 for control signals connections, and connector P2 for power and motor
connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins
and related issues are presented in section 4, 5, 9.

Details
DIR-
DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two
directions of motor rotation; in CW/CCW mode (set by inside jumper CN6), this signal is
counter-clock (CCW) pulse. For reliable motion response, DIR signal should be ahead of PUL
signal by 5μs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that
rotation direction is also related to motor-drive wiring match. Exchanging the connection of
two wires for a coil to the drive will reverse motion direction.
DIR+
PUL-
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each
rising edge active ; 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In CCW mode (set by
inside jumper CN6), this input represents clockwise (CW) pulse. For reliable response, pulse
width should be longer than 2.5μs.
PUL+
ENA-
Enable signal: This signal is used for enabling/disabling the drive. High level (NPN control
signal, PNP and differential control signals are on the contrary, namely low level for enabling.)
for enabling the drive and low level for disabling the drive. Usually left UNCONNECTED
(ENABLED).

Selecting Internal Microstep and Control Signal Mode
There are two jumpers CN6 and CN7 inside the DM860I specifically for selecting control mode and enable internal
microstep , as shown in figure 2. Default setting are PUL/DIR mode and enable internal microstep . (Note: a short
circuit jumper.is in reserve )
(a) CN6, CN7 open circuit (b) CN7 open circuit, CN6 short circuit
PUL/DIR mode and Enable internal microstep CW/CCW mode and Enable internal microstep
(c) CN7 short circuit, CN6 open circuit (d) CN6, CN7 short circuit
PUL/DIR mode and Disable internal microstep CW/CCW mode and Disable internal microstep
