三、Pin Assignment and Description3
1. Pin Assignment3
1）Control signal interface3
2. Control Signal Connector Interface4
Note: When the VCC value is 4.5~28Vdc, R is shorted or not connected;4
3. Sequence Chart of Control Signals4
4. Control signal mode setting4
Pulse Trigger Edge and Single and Double Pulse Selection: The pulse rising edge or falling edge trigger is enabled by the PC software ProTuner software or STU debugger. It is also possible to set the single pulse mode or the double pulse mode. In dual...4
5. Wiring requirements4
四、Current, subdivision DIP switch setting and parameter auto-tuning5
1．Current Setting5
SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current, and ON meaning that standstill current is set to be the same as the selected dynamic current.5
The current automatically reduced to 50% of the selected dynamic current one second after the last pulse. Theoretically, this will reduce motor heating to 36% (due to P=I2*R) of the original value. If the application needs a different standstill curre...5
2. Microstep Resolution Selection5
When SW5, SW6, SW7, and SW8 are all on, the driver subdivision adopts the default internal subdivision number of the driver: the user sets the subdivision number through the PC software ProTuner or STU debugger, the minimum value is 1, the resolution ...6
3. Parameter auto-tuning function6
When the driver is open-loop stepping drive, each parameter of the motor can be automatically recognized once at each power-on, and the driver can automatically complete the self-tuning of the motor parameters and internal adjustment parameters; when ...6
五、Power supply selection6
1) When wiring, pay attention to the positive and negative poles of the power supply.6
2) It is best to use an unregulated power supply;6
3) When using an unregulated power supply, the power supply current output capability should be greater than 60% of the drive set current;6
4) When using a regulated switching power supply, the output current of the power supply should be greater than or equal to the operating current of the driver;6
5) In order to reduce the cost, two or three drives can share one power supply, but the power supply should be large enough.6
六、Motor matching6
The DM542 can be used to drive 4, 6 and 8 wire two-phase, four-phase hybrid stepping motors with a step angle of 1.8 degrees and 0.9 degrees. When selecting a motor, it is mainly determined by the torque and rated current of the motor. The torque is m...6
1. Motor6
Tmotor=C（Jε+Tload）6
J: moment of inertia of the load ε: maximum angular acceleration of the load C: safety factor, recommended value 1.2-1.46
T load: maximum load torque, including effective load, friction, transmission efficiency and other resistance torque6
2. Connecting the Motor6
3. Typical Connection7
八、Protective function7
