More about PUL/DIR/ENA Signals
Pin Function
Details
PUL
Pulse signal: This input represents pulse signal; 4-5V when PUL-HIGH,
0-0.5V when PUL-LOW. For reliable response, pulse width should be longer
than 2.5
μ
s. Series connect resistors for current-limiting when using +12V or
+24V control signals (OPTO).
The same as DIR and ENA signals.
DIR
DIR signal: This signal has LOW/HIGH voltage levels, 4-5V when
DIR-HIGH, 0-0.5V when DIR-LOW. For reliable motion response, DIR
signal should be ahead of PUL signal by 5
μ
s at least. Please note that motion
direction is also related to motor-driver wirings and encoder feedback A/B
phase signals. Exchanging the connections of two wires of the motor to the
driver and A/B phase signals of encoder will reverse motion direction.
ENA
Enable signal: This signal is used for enabling/disabling the driver. High
level (NPN control signal, PNP and Differential control signals are on the
contrary, namely Low level for enabling.) for enabling the driver and low
level for disabling the driver. Usually left
UNCONNECTED (ENABLED)
.
ERR
Error signal: This pin will be pulled to LOW level (reference to
EGD
) when
driver goes into faulty status. There is a 10K resistor connected between
ERR
and
OPTO
.
Please refer to figure 2 in Control Signal Connections for
more details.
Control Signal Connections
The DCS303 has 3 optically isolated logic inputs to accept control signals. These
inputs are isolated to minimize or eliminate electrical noises coupled onto the
control signals. In the following figure, connections to open-collector are illustrated.
ERR signal can be used for error detecting and has the same reference (GND) with
PUL, DIR and ENA signal.
