Description

The DCS303 is a digital DC servo driver developed with DSP and high efficient MOSFET technologies. In position control, it's easy for the end users to change stepping drivers to the DCS303 without changing control systems, because its input command is PUL/DIR signal, which is compatible with that of stepping drivers. In low power motion control applications, performances of DC servo systems using the DCS303 are better than those of digital AC servo systems in velocity, precision, stability, or at least as good as those of digital AC servo systems. However, the cost of the DCS303 stays at the price line of stepping driver, namely far lower than those of AC servo drivers.

The DCS303 is a microsize brush DC servo drive. It is an ideal choice for those applications in which the mounting space for the driver is limited and higher output power is not necessary. 

The DCS303 is very easy to tune and all parameters are visible. Handheld and PC based tuning tools, including ProTuner (Windows based setup software) and STU (Small servo tuning unit) can meet different tuning environments or requirements.

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 2.5µs. 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 5µs 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 leftUNCONNECTED (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.
