PWMOUT used with Parker VPL/Pulsar valve
Has anyone had any luck using the bi-directional PWMOUT with the Parker VPL/Pulsar valve proportional coils? I tried using one Bi output for two coils on a 4W/3P proportional valve(each valve section has 2 separate coils, 1 for shifting the valve in each direction) and did not have much luck and had to eventually use one output per coil (used on the positive return side). Was wondering if anyone else had a similar problem or am I missing something? Any help is greatly appreciated.
small indicator
We need going to do small screen. MD4,MD3 not suitable for that aplication. Because it will only display. So MD4, MD3 screen operating is smilar that: You have got a shovel sand. But you are using a dozer for this work. For example to view the mobile crane balance. You can see 10 second
There vansco series. But we can not use in the iqan design platform. We can not programing multi master it. Canopen keypad and canopen indicator is the future thought?
MTTFd values for MC3 MD3 and XA2?
Do you have any values for these modules please?
Is there a new MD3 display?
Frequency input
Is it possible to use Frequency input to get the engine speed by using the W contact of the alternator?
Closed Loop Control with Voltage Outputs
I have a system that includes a dc motor, a dc motor controller, an MD3 master and XA2 expansion modules.
My overall objective is to control the output speed of the motor, through the motor controller, via closed loop PID control with the MD3 and one of the XA2 modules. The motor controller can accept a 0-10Vdc signal to regulate the speed of the motor.
Assuming I can monitor the rotation speed of the motor's output shaft via a frequency input or voltage input into the XA2 module but am uncertain of how I can output the 0-10Vdc output signal to the motor controller from the XA2 module, any ideas?
Thanks, much appreciated.
Is there a chart of the master and slave controllers that I can use as a quick reference for making my own?
