If you are using ISE >13.1 it only matters if encryption is used (its not)
I actually don't think it matters even on ISE < 13.2 as it seem more related
to Xilinx's core generator (which the source does not use for portability reasons)

Dual PID loops with motor encoder + scale encoder per axis

Category: Advanced Configuration

One thing I'm questioning is whether both the inner and outer PIDs should receive the same position command signal. It isn't really shown explicitly in the simplified Galil drawing, though the wiki example definitely does it this way.

Also, I want to make sure I understand the nomenclature. I think I wrongfully assumed this type of dual loop was a velocity loop (inner) and position loop (outer), but the outputs from both loops are velocities, so I think that's wrong. You can see my confusion in the initial configs I posted as I called the PIDs "vx" and "px".

Next up, the Prototrak DC servo amps are PWM input -> motor output voltage. Varying the voltage on an unloaded DC motor varies its speed (velocity). These are just amps and not closed loop drives - the motor encoder output just comes straight into the Mesa card. I am a bit confused on whether this is called "velocity mode," however. Is that term reserved for a drive which itself runs a loop with the motor encoder to maintain the commanded velocity?

Which leads me to wondering whether the velocity outputs from the motor encoders should be used. Andy, you kind of hinted at that the other day. I'm curious how you would see that fitting into this diagram.

Thanks in advance.

Hello, please can you help me, I make the config file and use ise desing 14.5 and got the warnig

PhysDesignRules:2410 - This design is using one or more 9K Block RAMs (RAMB8BWER).  9K Block RAM initialization data, both user defined and default, may be incorrect and should not be used.  For more information, please reference Xilinx Answer Record 39999.

Does this warning affect normal operation?
Thanks.

I'm also curious about using M19 for broaching on a 3 axis mill running a servo spindle. Seems like it should work but not sure how to execute.

It's been a busy week here, but I'm still working to wrap my head around this.  I posted a link earlier to a Galil video about dual loop compensation, and finally had a chance to watch it in detail.  It gives a good overview of the approaches and problems.  The proposed "improved dual loop" seems to be more or less the same approach that was described rather sparsely in the wiki.

Here's the video again: www.galil.com/learn/online-videos/dual-l...compensation-methods

And my re-drawing of their simplified dual loop.

 

To better my understanding I've been working through the process of translating that simplified loop to show the actual relevant HAL components and signals.  Here's my first approach.  It's much easier to understand and learn in diagram form than just seeing it as a pile of HAL commands.

 

I have not yet taken this back down to my shop to rework the config to match the drawing, but hopefully this weekend.  Anyone see any glaring mistakes or have other comments?

cheers,
Steve

It's probably:

addf mesa_ifm.00 servo-thread

If in doubt about function names, run linuxcnc with a working
configuration with the desired components loaded and then
run this command (in a terminal):

halcmd show funct

First of all: I am sorry, you was right I have problem in HAL: I forgot # before addf ;-) But when I enabled addf, lcnc cannot start, becouse cannot find function. I didn't found GS10 driver as you have, so I have tried to test example: modcompile relayboard.mod. It was compiled, installed, but the same problemn with addf. when I disable addf and leave loadrt only, lcnc starts and I see relayboard in halshow, not work, of course.

Need to enable dmks r8168 driver here?

#
#  EtherCAT master configuration file for use with ethercatctl.
#
#  $Id$
#
#  vim: spelllang=en spell tw=78
#
#------------------------------------------------------------------------------

#
# Main Ethernet devices.
#
# The MASTER<X>_DEVICE variable specifies the Ethernet device for a master
# with index 'X'.
#
# Specify the MAC address (hexadecimal with colons) of the Ethernet device to
# use. Example: "00:00:08:44:ab:66"
#
# Alternatively, a network interface name can be specified. The interface
# name will be resolved to a MAC address using the 'ip' command.
# Example: "eth0"
#
# The broadcast address "ff:ff:ff:ff:ff:ff" has a special meaning: It tells
# the master to accept the first device offered by any Ethernet driver.
#
# The MASTER<X>_DEVICE variables also determine, how many masters will be
# created: A non-empty variable MASTER0_DEVICE will create one master, adding a
# non-empty variable MASTER1_DEVICE will create a second master, and so on.
#
# Examples:
# MASTER0_DEVICE="00:00:08:44:ab:66"
# MASTER0_DEVICE="eth0"
#
MASTER0_DEVICE="68:1D:EF:38:F0:48"
#MASTER0_DEVICE="enp3s0"
#MASTER1_DEVICE=""

#
# Backup Ethernet devices
#
# The MASTER<X>_BACKUP variables specify the devices used for redundancy. They
# behaves nearly the same as the MASTER<X>_DEVICE variable, except that it
# does not interpret the ff:ff:ff:ff:ff:ff address.
#
#MASTER0_BACKUP=""

#
# Ethernet driver modules to use for EtherCAT operation.
#
# Specify a non-empty list of Ethernet drivers, that shall be used for
# EtherCAT operation.
#
# Except for the generic Ethernet driver module, the init script will try to
# unload the usual Ethernet driver modules in the list and replace them with
# the EtherCAT-capable ones. If a certain (EtherCAT-capable) driver is not
# found, a warning will appear.
#
# Possible values: 8139too, e100, e1000, e1000e, r8169, generic, ccat, igb, igc.
# Separate multiple drivers with spaces.
#
# Note: The e100, e1000, e1000e, r8169, ccat, igb and igc drivers are not built by
# default. Enable them with the --enable-<driver> configure switches.
#
# Attention: When using the generic driver, the corresponding Ethernet device
# has to be activated (with OS methods, for example 'ip link set ethX up'),
# before the master is started, otherwise all frames will time out.
#
DEVICE_MODULES="generic"

#
# Flags for loading kernel modules.
#
# This can usually be left empty. Adjust this variable, if you have problems
# with module loading.

for sure not set Ip adress manually and all enp3s0 is atumatic ... only ipv6 is disable .. like my other pc ethercat .... but not think is these the problem ... about these link up and down ..


r8168: enp3s0: link down
EtherCAT 0: Link state of ecm0 changed to DOWN.
r8168: enp3s0: link up

really .... whitout nothing doing after second reboot I have my ethercat running .... actually i have not an xml config running only an ek1100 + some el1008 and el2008 connecting to the system for latency test pourpuse ....
  1. after dmsk driver install latency test give me better result with min/max more or less 27usec ans svdev of 3.2usec .... previously with same q.ty of glxgear running I have min/max around 80usec .....
  2. as image attach show i have continuosly an snp3s0 connection activaction failed (that is ethercat line) with a lot of error on dmesg list ..... on dmesg as you can see I have unlink enp3s0 than link again .... why these? someone have some ideas why these? ... first time for me.
attach as spoiler dmesg text ...

Nice BHar, thanks for sharing. Gave that a shot; sure enough it works! Awesome.

Wanted to mention that I got autologin working by editing /etc/lightdm/lightdm.conf and changing `#autologin-user=` to `autologin-user=cnc`. There's also some settings in there for VNC but they seemed irrelevant (for tigervncserver anyways.)

Ok I sorted it, was a setting on the driver... like an stupid one. Thanks heaps everyone, I was going to dark places there. Now I got to sort out the dual motors on 1 axis, some are jogging only one direction, and the scale is wrong. And homing. I got alot to do, briefly seen other peoples topics on these while running around in circles so I will be a while with that. Thanks heaps
