Drive function | Instructions |
Speed range setting |
The four DIP switches SW5~SW8 are used to set the speed range of the drive. There are 16 speed ranges in total. When the user sets the speed, the drive should be stopped first. For the setting of the specific speed range, please follow the instructions on the drive panel. |
Output current setting | 8 output currents can be set for the Driver through 3 dial switches SW1~SW3. See driver panelinstruction for output current settings. |
Automatic half -flow function |
Automatic half current function can be set for the Driver through switch SW4. OFF means that quiescent current is set to half of operating current; ON means that quiescent current and dynamic current are the same. SW4 shall be set as OFF for general use to reduce heat generation of the motor and the driver and to improve reliability. About 0.3s after pulse train stops, current will automatically reduce 50%(actual value 55%) and theoretically, heat generation will reduce 65%. |
Signal interface | PUL+ and PUL- are the motor start control terminals, which support 5V or 24V switching signals; DIR+ and DIR- are the positive and negative terminals of the direction signal; ENA+ and ENA- are the positive and negative terminals of the enable signal. |
Motor interface | A+ and A- connect to positive and negative terminals of A phase winding of stepper motor; B+ and B- connect to positive and negative terminals, When A and B phase windings are switched, the Motor direction on will be reversed; |
Power connector | DC power supply, operation input voltage range: 20V~50VDC, 36VDC operation voltage is suggested, power supply shall be higher than 100W. |
Indicator light | There is 1 green indicator light and 1 red indicator light on the Driver. The green one is power indicator light, it illuminates when the Driver is connected to power supply; the red one is failure indicator light, it illuminates when over-voltage or over-current failure occurs. Red indicator light goes off after failure is eliminated. Failure of the Driver can only be eliminated by re-connecting to power supply and reusing. |
Installation Notes |
Dimensions of the Driver:117x78x34mm, installation pitch of holes: 111mm. Both horizontal and vertical installations can be selected (vertical installation is suggested). The Driver shall be installed closely against metal cabinet for heat dissipation. |
The speed range, dynamic and half/full current of the MC542P-2 drive can be set as follows through the 8-bit DIP switch:
