Description: Normal 0 7.8 磅 0 2 false false false EN-US ZH-CN X-NONE This item includes: 1 PC Stepper motor driver DQ542MA Introduction: DQ542MA is a type of two-phase hybrid stepping motor driver, the drive voltage of it is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts is smiliar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Holding torque when DQ542MA run under high speed is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.

This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver.ENBL-ENBL- is the negative end of direction input pin. Usually left unconnected (enabled) Function choice ( Using DIP pins to achieve this function) 1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table: SW5OFFONOFFONOFFONOFFONOFFONOFFONOFFONOFFSW6ONOFFOFFONONOFFOFFONONOFFOFFONONOFFOFFSW7ONONONOFFOFFOFFOFFONONONONOFFOFFOFFOFFSW8ONONONONONONONOFFOFFOFFOFFOFFOFFOFFOFFPULSE/REV400800160032006400128002560010002000400050008000 2) Standstill current setting 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 is set to be the same as the selected dynamic current. 3) Output current setting: The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current.
