Negative PWM

Hi All,

We have a motor that requires a PWM negative signal. Using an MC42, anyone ever done this? if so, how?

How to calculate speed of a BLDC motor with quadrature encoder

Vignesh Namasivayam 3 years ago in Master modules / MD4 updated 3 years ago 2

Hello all, 

I am trying to do speed control of a BLDC motor with a Parker MD4. I have a quadrature encoder for the motor and would like to know how to calculate the speed for the motor using the IQAN Design software. I can calculate the position of the motor from the sensor, but to estimate the speed in rpm, I need to perform differentiation of the position data. I wanted to know if there is a channel/library/block that will give speed outputs or will do differentiation? Or should I write my own Qcode for differentiation?.

Can't connect to MC42FS

Jacob Eklund 3 years ago in Master modules / MC4x updated by Gustav Widén (System support) 3 years ago 1

I am having problems connecting to a MC42FS.The PLC worked fine last friday but when trying to upload some weekend changes this morning the PLC suddenly stops working. On the first programing attempt after power-on the programing process stops at "stopping applications" followed by a "no handshake replay". Trying to program the PLC after will only result in a "no handshake replay". If connecting to the PLC after cycling the power with IQAN run i get the following error. "There is no valid application in the target module. Error code R4:2 1:1:1 (Int.diag error(Backending?)) MS42FS[NI address tag] (FW version 6.04.4) i have tried multiple times with and without the ID-tag, but nothing changes. Any ideas on how to get it working again?

'Wrong ID Tag' for single module MD3 system

Anthony Le 4 years ago in Master modules / MD3 updated by Gustav Widén (System support) 4 years ago 3

Hello,

Does an MD3 require an ID Tag if it's being used in a single module network? The only other module on the CAN network is a non-IQAN J1939 module (engine ecu.) This is how we communicate with the engine. The machine did not have an ID tag when it was built back in 2010 and we recently replaced the MD3 because the screen was too dark to read. We had some problems opening the original ida file because it was an old beta version. So we had to pull a clone file from the existing MD3 and saved it as an ida3 before sending it to a new replacement MD3. After installing the new MD3 the 'Wrong IdTag!' error appears. I've searched this forum for answers but can't seem to find this particular case. Is there a new address requirement for MD3's that was not the case back in 2010? Did saving the file from ida to ida3 cause this problem?

XC10 DOUT(LS)

Richard Kowalczyk 4 years ago in Expansion modules / XC10 updated by Gustav Widén (System support) 3 years ago 2

Hi everyone,

I have been working on a quite complex system. When using XC10 all relay coils (or valve solenoids) controlled by DOUT(LS) have been powered from +BAT and it has been working fine. However checking program, for no reason, have found in the the Instruction book that one or more DOUT should be used to power these coils or solenoids. Is there any risk with what I am doing ? I have checked that for MC43 and MD4, that I have been using on the same system, it is allowed to use +BAT for power. I can of course do it by book but the program would become a little bit awkward and messy.

Any comments will be much appreciated

Hello,

I have a situation where need to get data from a weigh system with RS485 modbus onto the canBus and in to a MD4.

Can you suggest a gateway that I can use for this?

Cheers,

MD4-5 orientation

When using the MD4-5 in portrait mode are the large C1 & C2 connectors at the top or bottom of the module?
