Hello,  my OEM says they are using Digital inputs 1 - 4,  based on the parameter could you explain which inputs would need to be high = 1 to get the motor to move and what determines the speed reference?

Thank you

 I apologize if i was not clear, this is how the parameters are set in the drive and we use inputs 1-4 to operate the motor, however I was unable to determine which inputs need to be turn on in conjunction to work,  the electrical drawing has input 1 = start,  input 2 = CW , input 3 = CCW,  input 4 = HI / LO,  so does input 1 plus either input 2 or input 3 for direction and based on status of input 4 it would use this as the speed reference HI / Lo, basically it's set up to use fixed frequencies,

Input 1, start, as the inputs 2 and 3 give the 'run' command, 'start' does not apply to this drive, the power is applied and the drive is ready to run, either CW or ACW, depending upon the closure to input 2 or input 3 of a HI signal.

Input 2, set P052 = 1, the motor will run ' ON RIGHT'.

Input 3, set P053 = 2, the motor will run 'ON LEFT'.

Input 4, set P054 = 13, the 'setpoint' can be switched between analogue and fixed frequency control.

I hope this answers the question, I have attached a scan of the digital input page. I do not have a drive of this type so cannot test these things other than looking at a very old manual.

Come back if I can help further.

 thank you for all your help, here is the electrical print with the inputs to the drive,

Having difficulty seeing how this can work with Micromaster Vector.

From the drawing, Din2, Din3, or Din4, are being activated when Din1 is selected high. I cannot see a way of replicating this with Micromaster Vector.

As I have shown, each Digital Input Din2/3/4, when high make the selection required when high, making Din1 surplus?

I believe some manufacturers operate as shown in your drawing, Danfoss and ABB perhaps?

Thanks for the reply and 'follow up'.

 it connected to a plc, which certain outputs come on that make certain inputs high, this is exactly how it is hooked up in our plant, i sent the picture of the drive in an earlier post, you may be able to make out the wire numbers and terminals, based on how our drive is wired, and the parameters i sent in the earlier post of fixed frequencies,  so if only input 2 is made high parameter P52 = 1 H  = ON right, would anything happen, I should probably try to look in the plc program and see which outputs are sent to the drive for rotate right high speed, rotate right low speed, and the same with rotate left, Thank you for all your time and help

Hi

I can see the following are possible, I am assuming the setting's are as below, possible, as I do not have sight of actual parameter settings:

Input 2, set P052 = 1, the motor will run ' ON RIGHT', (Din6, 1202).

Input 3, set P053 = 2, the motor will run 'ON LEFT', (Din7, 1203).

Input 4, set P054 = 13, (Din8, 1204), the 'setpoint' can be switched between analogue and fixed frequency control.

Now:

K3505 is a contact connected to Din1, 1201 / 6516, without a parameter setting for this, I cannot be sure what it does, I doubt it is a 'START' command.

I suggest it is connected, and see what happens when it goes high. Or send me the parameter setting for P051?

Do you have the manuals available for this drive?

 here are the parameter settings

From the settings:

P042 = FF2 set to 55Hz.

1201, Din1, P051 = 6, select fixed frequency, 'this may be a START command'.

1202, Din2, P052 = 1, on right.

1203, Din3, P053 = 2, on left.

1204, Din4, P054 = 6, fixed frequency set to 55Hz.

Notes:

Closing Din1 may be the START, unable to confirm this without having a device here to evaluate.

Frequency setpoint source, P006 = 2, this should be selected.

 my only question now would be if I only had two inputs high what would be the fixed frequency it would use?  for instances if only 

1201, Din1, P051 = 6, select fixed frequency, 'this may be a START command'.  = high or 1

1202, Din2, P052 = 1, on right   = high or 1

1203, Din3, P053 = 2, on left.    = low or 0

1204, Din4, P054 = 6, fixed frequency set to 55Hz.  = low or 0

It should turn right, but at what speed? input 4, is how it selects high speed or low speed
