Page 6: Pin Assignment And Description
Full Digital Stepper Drive DM2282T 3. Pin Assignment and Description The DM2282T 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. -
Page 7: Rs232 Communication Port
The DM2282T can accept differential and single-ended inputs (including open-collector and PNP output). The DM2282T has 3 optically isolated logic inputs which are located on connector P1 to accept line drive control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals. -
Page 8: Connecting The Motor
(common-anode) 5. Connecting the Motor The DM2282T can drive any 2-pahse and 4-pahse hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In setting the drive output current, multiply the specified phase current by 1.4 to determine the peak output current. -

6. Power Supply Selection The power supply voltage can work normally between the voltage range specified by the driver. The DM2282T is directly powered by AC. It is recommended that the user use the highest voltage lower than the driver's specified voltage to avoid the grid fluctuation exceeding the driver voltage operating range. -
