XC43 Functional Safety

Michael Carlyle 3 years ago in Expansion modules / XC4x updated by Gustav Widén (System support) 2 years ago 6

Will the XC43 (when paired with the MC43FS) inputs to be allowed for use in Functional Safety Marked Function Groups in a future version of IqanDesign?

Driving Low Dither Frequency Valves with XC4x Current Outputs

Justin Wagner 3 months ago in Expansion modules / XC4x updated 3 months ago 2

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.

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?

XC44 HS+LS Overcurrent

CalebD 2 years ago in Expansion modules / XC4x updated by Gustav Widén (System support) 2 years ago 10

We are experiencing a problem with the HS+LS outputs on an XC44 module connected to an MC43 as the master running IQAN 6.07. Pin C1:46 as the HS and pin C1:41 as the LS.

The outputs are being used to activate a solenoid. The circuit was wired to run through a relay latched by system estop, with a diode placed across the solenoid to protect the outputs as in the documentation.

Image 2927

This circuit is able to latch and unlatch the solenoid with no problems, and this was repeatable many times. However when the system estop is pressed for the first time and the relay unlatches and breaks the circuit there is no error. When the relay is energized and the circuit is connected again, when the output is turned on a message is displayed reporting that the LS pin is overloaded. This message then triggers on either side of the estop from that point on. Key cycle is able to "reset" to the first estop cycle. This behavior happened ~9/10 times the cycle was repeated. There were some occasions where the error did not trigger.


The overcurrent error will only trigger when the output is requested, the estop relay can be re-energized connecting the circuit and no overcurrent is reported. 

Current measurements were taken on the HS+LS wire to investigate. The current on this wire never approaches or exceeds the listed 2.5A. This is the only load on that pin grouping, the other 3 LS pins were not used.

XC4x C1 Harness

Lars Bolduc 2 months ago in Expansion modules / XC4x updated by Markus Seppänen 1 month ago 2

Hello,

This is a small but frustrating nitpick.

The XC4x C1 Prototyping Harness (Parker no. 20085116) comes with wires installed in the C1:4 and C1:20 position.

This is annoying, because in order to use these modules, you need to install the ID Tag. (Parker no. 20085131 for example)

So every time you use this (expensive) part, you need to de-pin these two wires, remove them from the harness, and install the ID Tag.

Ideally there would be no wires present in these slots.

Like the older style XA2 Prototyping Harness (Parker no. 5030030).

Regards,

XC43 DOUT HS in parallel

Jamy 4 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 4 months ago 1

When connecting loads to high side digital outputs in parallel, the manual says on page 96 "Increased drive capability
Power driver high-side is connected in parallel with adjacent output to drive double
load current
." On page 116 it states the max load per output is 4 amps and max load per group is 6 amps. So when you connect in parallel is the max load 8 amps? Or 6 amps?

XC43 Current Outputs Bounds for short and open load

Thomas Murgolo 7 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 7 months ago 1

Hello, I am working with an XC43 current output that controls a bidirectional valve and want to make sure I use the right resistor to avoid problems with getting short and open load errors. I have found the minimum resistance for my case is 20ohms based on Appendix A in Parker's Family instruction book, but I am not sure how to find the maximum. Any help would be appreciated.

Current leakaje XC42/43/44

Jesus 11 months ago in Expansion modules / XC4x updated by chuck streb 3 months ago 4

Hello, I have a current leakage problem in the XC-43 and XC-44 modules.

I am using Digital Out HS outputs to drive LED blinkers, but they don't turn off completely, there is a 5.8V voltage leakage. The flywheel diode is installed but we have had to install some power resistors in parallel to get them to switch off completely. The same problem has appeared when connecting a buzzer to Digital Out HS.

XC42 blink code R4:3 3:1:6

Adolfo 1 year ago in Expansion modules / XC4x updated 1 year ago 2

Hello,

We have a customer with this error pattern in one of the XC42 installed in the machine: R4:3 3:1:6

But we can’t find this pattern in the manual.

Can you explain what this blink code means, please?

Best regards 

Adolfo
