Need help wiring a PMDX 107 to a Delta VFD-M
« on: July 25, 2016, 10:33:58 AM »


These are the wires from PMDX107.  I do not know where to connect these wires to the Delta VFD.



PMBX 107                      

Rev/Dir            
Fwd/Run            
COM               
Aref               
Aout                        
Agnd                
               

Delta VFD-M

Forward/Stop      MO
Rever1se/Stop      M1
Reset                    M2
Multi-Step  1        M3
Multi-Step  2        M4
Multi-Step  3        M5
Common Signal   GND

Based on the manual that I found here:
http://www.delta.com.tw/product/em/drive/ac_motor/download/manual/VFD_M_EN_20100514.pdf

page 2-2 shows the basic wiring needed.  From that, here are the connections:

PMDX-107         VFD
-------------       -----------------------
Rev/Dir             M1 (reverse/stop)
Fwd/Run          M0 (forward/stop)
COM                GND

And as per figure 2 on page 8 of the PMDX-107 manual (also note the PMDX-107 DIP Switch #6 setting):
Aref                 No connection
Aout                AVI
Agnd               GND

The PMDX-107 DIP switch settings should be:
* "Normal Mode" (see section 4.1 in the PMDX-107 manual)
* Solid State Relays as Forward/Reverse (see section 4.2)
* Charge Pump Enabled (see section 4.3, presuming this is on a PMDX-126)
* Fast filter response (see section 4.4)
* 10V reference (see section 4.5 and not above for analog connections)

You may also need to reprogram some register settings in the VFD to get it to pay attention to the Forward & Reverse inputs and the analog control voltage (instead of the VFD front panel controls).  At a *very* quick glance, look at VFD registers Pr.00 and Pr.01 and set both to "01".

Hey Bob, thanks for that answer, i have a Delta VFD-E, im from Argentina and i have a pmdx 107, can you help me with that VFD?

Im think that should be:

PMDX-107         VFD
-------------       -----------------------
Rev/Dir             M2 (reverse/stop)
Fwd/Run          M1 (forward/stop)
COM                DCM

Aref                 No connection
Aout                AVI
Agnd               ACM

am i correct?? please help, and thanks!!!!!

Hi Alito,

Your list of connections look correct except that the Delta manual
refers to the terminals as MI2 and MI1 instead of just M2 and M1.
Your connections match those in Figure 1 in the manual that I was
able to download.

Keep in mind that all of the MI signals can be configured by setting
parameters and the diagram in Figure 1 assumes the factory default
parameter settings. If they have been changed, you will need to put
the back to the factory defaults for the MI2 and MI1 inputs.

There are other parameters to set the terminal strip as the source
of run commands and speed setting. The factory defaults for these
usually permit control from the keypad, but this unit seems to have
the factory default using the terminal inputs. The parameters for
this appear to be 02.00 and 02.01 for selecting the input mode.

Regards,

hi again, i have another doubt about this, My spindle have a ptc thermal protection, and in the manual of this VFD, also point me that i have to wire in the AVI, ACM.
can i conect the pmdx 107 and the thermal protection??

thanks!!!!

You must choose *either* 0-10V speed control from the PMDX-107 *or* the PTC thermal protection.  They both use the same ACM/AVI terminals.  On page 172 (of the manual that I could find), in the section that described register 07.14, it says:

Quote
When the source of first/second frequency command is set to AVI (02.00=1/02.09=1), it will
disable the function of motor PTC overheat protection (i.e. Pr.07.12 cannot be set to 1).

So I guess the answer is either don't run the motor at a "low" frequency for very long, or provide an external fan to cool the VFD.  It looks like this could be controlled by the "Thermal Overload Relay" and registers 06.06 and 06.07, along with register 03.01 (value 14) to route this function to the MO1/MCM terminals.
