CPLD STEPPER MOTOR DRIVER

  • No Comments

Learn how your comment data is processed. This site uses Akismet to reduce spam. We recommend no more than a 44volt supply for reliable and trouble free operation. The maximum motor rpm was step rate limited by the PC. Higher step rates is possible by using a faster computer. Adjustable chopper current drive, no large external resisters required for stepper motor current limiting. Notify me of new comments via email.

Using higher microstep rates will decrease the chance of motor resonance affecting performance. Only one stepper mode can be programmed into the CPLD at one time, please state which version required when ordering. Stepper motor voltage set to 36volts, using 8 microstep mode. MicrostepPLD silkscreen layout by part number.

We recommend no more than a 44volt supply for reliable and trouble free operation. Modern lower voltage stepper motors achieve much higher rpm speeds and should be used if high speed is required in your application. Also available is a parallel port Stepper Breakoutor our latest optical isolation board. You should be able to use just about any gear you have on hand. Notify me of new posts via email. We do not sttepper the use of a full or half step drive due to cp,d likelihood of motor resonance.

Standard TTL step, direction and enable inputs. We suggest using cardboard floppy disks envelopes that can be purchased at office supply stores. We have tested the LMD driver chips continuously with a 44volt power supply.

Email required Address never made public. For those only interested in purchasing a single bare pcb board, shipping and handling can be avoided by sending us the cost of the pcb and include a self addressed stamped envelope with your order. Bare PC boards are in stock. If this leaves you thirsting for more CPLD goodness check out our own guide on the subject. mtoor

Stepper motor test video. Professional quality board with silkscreen. You are commenting using your Facebook account. We recommend the 8 microstep version and will ship this version if you do not state your preference. Notify me of new comments via email.

For Astronomy users, MicrostepPLD can be used to control your telescopes azimuth and altitude stepper motors using 10 or 16 microsteps for smoother movement. Stepper motor is spinning at a maximum rate of RPM.

The LMD driver has internal overcurrent and thermal shutdown protection.

This is useful for larger machines that use dual lead screws per axis. Requires external volt DC motor supply. We recommend the 8 microstep version for most applications.

No assembled units or parts kit are available.

TurboCNC is able to output an exceptionally smooth pulse train; this maximizes the stepper motor performance and speed. Just change the quantity to 5 and mofor add list to order.

Although motkr driver chip can handle 55volts, there should be some safety margin for stepper motor induced back EMF voltage.
