LSL with full Latching/Detent

Barth Hollanddrain 8 years ago updated by Johan Lidén (Product manager) 8 years ago 1

Is there any development in an (for example) LSL jostick with full detend/latching

So that the joystick stays in position.


We've had a couple occasions where this would be a great solution.

Answer

The IQAN-LSL joystick is available with different detent options, both mechanical and electromagnetic options with different characteristics like detent postions and spring forces. You can read more about them in the datasheet and instruction book.

Driving Low Dither Frequency Valves with XC4x Current Outputs

Justin Wagner yesterday at 10:16 a.m. in Expansion modules / XC4x 0

Has anyone had any success controlling valves that specify a low dither frequency below 71Hz with the XC4x current outputs?

We have a machine that is using a HAWE valve that specifies a dither frequency of 40-70Hz with 55Hz recommended. It also gives a range of dither amplitude of 20%-50%. The minimum frequency of the Cout channels on the XC4x modules is 71Hz. I'm sure 1Hz is not going to make a big difference if we set the frequency to 71Hz, but just wanted to see if anyone has had any similar experience or other recommendations. Just trying to avoid any possible stiction/hysteresis/chattering issues.

Watchdog Fault on MC41 when almost exceeding DOUT-HS Current (4A)

Kai Rasporich 2 months ago in Master modules / MC4x updated by Gustav Widén (System support) 2 months ago 2

I'm hoping someone might be able to chime in if they have seen something similar before.

I'm driving two contactors (they close at different times) off the MC41. The contactors at peak draw 3.9A for about 75ms. When the contactors close, a very short time later, the MC41 enters a critical fault. The flashing lights (4R, 1Y, 12Y, 3Y, 1Y, 2Y) seems to indicate there is a 'watchdog' fault. Looking at my CPU/RAM usage and cycle usage, we are not even using 1% capacity. Is it possible this overcurrent condition could trigger this particular fault?

As well, I can't seem to find any information on what the 12Y is supposed to mean? "R4:1 n:3:1:2" which would be the "n" in the manual. What would the 12th part of the software mean?

XC4x Firmware Updates

Chris Litwin 1 year ago in Expansion modules / XC4x updated by Gustav Widén (System support) 1 year ago 4

Say you have a brand new XC43. The firmware installed from factory is 1.0 (I think). How many times will the firmware update before reaching the current version of 1.03?

Also, the XC4x SIC module status lists a value of 140 as Firmware update. From the documentation that means the firmware update failed. Are there any other status values pertaining to the firmware? 


What are the different values possible in the system info "InternalState" and is this channel accessible in the project?

MC2 vs MC43 open load

Aderas verdes 1 year ago in Master modules / MC4x updated by Gustav Widén (System support) 1 year ago 1

Hi!

Previously we used MC2 in a project. Now changed master module in the program to MC43.

We have a DIY test board (large resistors with LED for indication) to double check if the machine sends signal to valves etc.


Using COUT channels...so connectors come in pairs. With MC2 if one of the connectors wasn't connected to a load it would display "open load" error when machine would send a signal to a valve that isn' t connected, but connected one would work when output is signal is given. (no open load error when joystick is in neutral)

Now with MC43- both COUT pair connectors have to be connected for it not to display "open load" error..even when joystick is in neutral position.

Is this because MC43 diagnoses itself differently than MC2 or is there something to be changed in the program?

Intermittent overload COUT error

SJ L 1 year ago in Master modules / MC4x updated by Gustav Widén (System support) 6 months ago 8

Hi, I have an issue with intermittent MC43 COUT overload errors on one of our machines.

Status is OK and operates well in most conditions, but will randomly report overload (even when that function is not requested).

I have tested the solenoids, plugs, and wiring harnesses within this circuit and all looks ok.

COUT circuit C1:16, 41, 57.

Is there anything else I should check to see what might be going wrong?

LM3D conversion kit

Niklas 2 years ago in Levers 0

Hydraulkompaniet in Sweden have put together a plug-n-play solution for replacing LM3D joysticks. No software update or wire harness modification is necessary in the machine. Just install the connectors and the LC6 with the mounting adapters. 

Its possible to use the 4th axis of the two LC6 joysticks to control extra functions on the machine to even add more value to this conversion. The MC41 have 2xCOUT that will be used in this case, the externa supply needs to be connectet if COUT is used.

MDL C2 Programming Connector 5030110

Evert-Jan 2 years ago updated by Gustav Widén (System support) 2 years ago 2

Does anyone have information about the MDL C2 connector and connections?

Because programming cable 5030110 is no longer available, I have to make this cable myself.

COUT open load error calculation

Justin Wagner 2 years ago in Master modules / MC4x updated 2 years ago 4

We have a machine that has sporadic nuisance open load errors on a function controlled by a unidirectional current output (COUT-G) on an MC43. Since this happens with some frequency, I suspect we are right up against the limit of the open load detection threshold. They test out well in assembly, but any increase in resistance occurring in the field might be setting it over the edge of the error threshold.


How can I calculate at what load resistance, commanded current, and supply voltage an open load error will occur?

This function is controlled with a Parker CCP024H 1/2" super coil with nominal resistance at room temperature of 30.30 ohms. Machine runs on 24V (around 28V when alternator charging). Maximum commanded current is set to 600mA.

Using Current Out as 4-20 ma signal for VFD

Barnhart Crane 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 2

Are the current out channels on an MC43 suitable for dishing out a 4-20 ma signal? It would be controlling a VFD.


I know the current out channels are typically used to control valves and used in the hundreds of milliamp range.
