Generally driving Danfoss PVG valves with IQAN Control system, we advice using the PVHC control option from Danfoss. You can drive the PVHC direct from the IQAN COUT current control output, Simple and works well. Ratiometric input signal requred by PVEM series cannot be controlled by IQAN available Outputs, same for PVEP PWM signal controlled modules as they have high input impedance (5 kOhm), requiring extra Pull-down resistors to connect to IQAN PWM output Another, more expensive, option is using Danfoss CAN control module PVED series, then need to include CAN protocol in your IQAN application
Hello, Within Parker IQAN we have different master modules and I/O modules having 1 to 4 Directional Pulse counts.
In IQANDesign you can easily add multiple modules in your System Layout, add your required I/O, including the Directional Pulse Count inputs, and move these around the different modules for optimal I/O distribution over the modules in your application.Parker IQAN modules are designed with flexible use of different type In and Outputs, however it is not possible to meet every application I/O list matching excactly one ore more module. There will be always a compromise to be made, however that benefits having some spare I/O in your system for future expansion and options.
There is more news to come on GT Modem and Telematics/IoT planned for late September.
Drop me a mail when you have specific requirement now.
In IQANDesign under "Tools " you find "Product Documentation" There you can select the information you want to have printed or saved as HTML . Simple and effictive IQAN way.
The Parker D1FBExx proportional valve range (no onboard electronics versions) perform very well driving them with IQAN Modules COUT current control. For more detailled information on the D1FBE valves see the catalog and manuals: http://www.parker.com/literature/Hydraulic%20Controls%20Europe/Manuals%20UK/D_1FB%205715-593%20UK.pdf, and http://www.parker.com/literature/Industrial-Systems-Division-Europe/Catalogues/Industrial%20Valves%20UK/03/D1FB%20UK.pdf.The IQAN COUT current controlled output can control up to 2000 mA (XA2, XT2) and 2500 mA on MC4x modules, is based on PWM modulation with current measuremente and control. Dither frequency and dither amplitude need not to be adusted, just select proper PWM frequency generally listed in datasheets of the proportional valves.For the D1FBE valves PWM frequency should be set > 100 Hz, generally we have very good performance and low hystereses using 335 Hz PWM frequency setting in IQAN COUT channels driving D1FBE solenoids. Note: You don't need to do build your own PWM control with timers, in IQAN the build in PWM and COUT outputs are special designed for driving proportional solenoids.
Hello, Please check if you have connected the Adress tag?
If you start-up IQAN MD4 display's without Adress tag , it will start up in safe mode
On IQAN system we have system communication ports in CAN: J-1939, or Genereic CAN (CAN-Open)
The Ethernet ports are implemented for Diagosics interface with PC tools, and IP Camera's . Maybe in future Ethernet ports could be used for communication purposes, but not yet in further develomemt .
The Parker IQAN system is more and more succesfully used in Industrial type controlsystem replacing PLC's and Industrial HMI interfaces.
In order to have the IQAN CAN bus to communicate with subsytems using Profibus, Modbus, EtherCat, Profinet, etc.. CAN Interface gateways are succesfully used, for example Anybus gateways : https://www.anybus.com/technologies/industrial-ethernet/modbus-tcp
Trust this helps
Request has been raised mor often, there are many more customers are asking for LSL with frinction detend option, Mainly for setting manually speeds on hydraulic motor functions in both directions

Hello The Parker Pulsar is fast switching on-off valve, see working principle in VPL series Parker Mobile Valves catalogs. That's why it needs square PWM to operatie well.
Maybe also good solution for large number of DM1 messages: SPN and text message ( In multi languages
