[ACC-24E2A Schematics]

Hi, vitaliy

 

Please send a request email to support@deltatau.com , addressing to Steve.

He will answer your question.

Thank you very much

 

 

Hi,

 

I am designing the hardware which interfaces the ACC-24E2A. The electrical diagram would help a lot. Unfortunately, the schematics on the bottom of the User Manual for Accessory 24E2A from April 15, 2010 has partial corruption and doesn't show most of the first page and part of the second page.

 

Can I get the complete diagram?

 

Thanks,

Vitaliy

[linear motor]

Hi,

 

encoder line should be encoder line spacing, which, in your case, should be 50nm.

electircal cycle (or commutation cycle) means the distance between your poles.

Phase position resolution is the smallest unit of your hardware count.

 

Example :

A linear brushless motor has a commutation cycle of 60.96 mm (2.4 inches). It has a linear scale with a

20-micron line pitch. The scale is used for both commutation and servo feedback.

The commutation uses the hardware counter. There are 200 hardware counts per millimeter (5 microns

per count), so 12,192 hardware counts per commutation cycle. Ix70 should be set to 1, and Ix71 should

be set to 12,192.

 

encoder line ｃｏｕｎｔ (um) ?

electrical cycle (mm) ?

phase position resolution ?

 

I want to ask what are those meaning for linear motor? please tell the detail! thank you! My grating resolution of my linear motor is 50nm,it is to say that 1VM=20cts!

 

 

[GeoBrick Axis Homing]

There are three problems in this: 1. It's better to use a PLC rather than a motion program to do this. 2. "#2HM" is an online command, when you compile your motion program, it should give you an error for that line. Please check the manual for the homing command. The command of homing in motion program is "HOME n", where n is motor number 3. If you use motion program to do homing, right after "HOME n" command, you need to have a wait time to wait for the motor to home. Also check Ixx97 to see if you set the flag capture right. [quote='rhombusvs' pid='582' dateline='1280423415'] Hi I've got a geobrick with 6 axes used (out of 8) #1..4,#7,#8 and I am having problems getting the motors to home to the PLIMx flag All the limits work when I have 1xx24=$1 so I know the limits are OK. I have used one of the homing routines from the user manual as a template and come up with this CLOSE OPEN PROG 102 CLEAR //Home Z1 down I224=$20001 ; Disable hardware limits I223=5 ; Home speed 5 cts/msec negative direction I226=-15360 ; home offset to get off switch I7022=2 ; Capture High level flag I7023=1 ; Use PLim2 as trigger flag #2HM ; Do actual homing move I324=$1 ; Re-enable hardware limits CLOSE With Imn22=2 the axis starts to move and then stops, as if it instantly sees the limit flag (even though it is nowhere near it) With Imn22=10 (low Flag Level) it moves continuously to the correct limit but does not see the flag. What am I over looking? Graeme [/quote]
