I have a question regarding the use of non-standard motors for external axes. The motor must have a 40 mm frame side (i.e motor flange width) and be controlled synchronously (i.e. by using E1... values in the main program).
Using a KSD (Kuka Servo Drive) with a smaller servo motor
The smallest compatible external axis servo motor offered by KUKA is MG_8_40_45_S0 (Art No. 00-131-269).
This motor is basically a Siemens 1FK7 motor (exact part No. is 1FK7022-5AK71-1YH3-Z S24).
Looking at the 1FK7 data sheet ...
There is a smaller motor (20 mm shaft height) within the range: 1FK7015-5AK7. This is the size I want to use. It also is rated for 600 VDC.
If I modify the part number to get a smaller frame size I have:
which is shown on the Siemens website:
... but ...
It appears some of the part numbers can't be identified within the Siemens catalogue (they are proprietary to KUKA).
"Y" "Z S24"
I have contacted Kuka and Siemens, but neither of them are cooperative and give information about the resolver type "Y" and whatever "Z S24" is.
Does anyone have any insights?
Can anyone suggest a way of controlling the position of an external axis by reading the E1 values ($AXIS_ACT_MEAS / $AXIS_MOT ?) and using them to control an external motor via a PLC.
So far it has been hard to find info about the how virtual axes work...
Any help greatly appreciated :)
I came across your thread on robot-forum (https://www.robot-forum.com/robotforum/thread/40682-non-standard-motors-for-external-axes/) and don't really have anything to add beyond what panic_mode posted...
Sorry that I cannot help you with that!
