Testers.... This is in regard to the action and state of the onscreen RESET button. If memory serves me correctly, when an alarm or the ESTOP was triggered in earlier versions the VCP RESET button state was changed to RESET TRIPPED. This action does not occur with the current release v5.08. The foll...

Thats what I get for AVID 20t on motor 64t on pulley 20t spur gear:

For Guys that wish to use the C86ACCP interface board, here is a doc that simplifies the installation and allows you to test/bench test a single motor, etc.

Also does the PSU (MEANWELL RD-35B) that comes with acorn board have enough power for 5 NPN proximity switches?

thanks John.

Yes, and Yes

Update April 2024.... We are now offering a lesser cost modular version of the Acorn 4 C86ACCP controller for ClearPath servos. Featuring M12 connectors for inputs and a matching 14 pin connector for spindle control, including CNC Depot ATC spindles. Compatible with up to 2 Teknic power supplies, in...

This may help a bit...
1 rev per minute = 360°/min
1 rev per second (60 rpm) = 21,600°/min

Depending on your hardware neither one of the above are considered very fast. I routinely set my max rate at 144,000°/min for low reduction wood cutting, with fast jog at 7200 and slow jog at 720

2.5 to 1 is seldom enough reduction to return good results. That said, you need to know exactly what the reduction ratio is. Divide that number by 360 and you will have your turns per degree.

For example for 2.5 to 1 reduction: 2.5/360 = 0.006944

Due to the age of those drives there is no guarantee that they will work properly when connected to a modern controller. That said, after looking over the provided manual, all the info for connection, including the use of pull up resistors is in there. Connect to the step/direction pins and common o...

Connect those LeadShine (clone) drives to the DB25 connector and make sure that you do not connect to the enable pin on the drive

Why not use the existing "Machining Envelope" feature?
