Can someone kindly verify these settings for my Durapulse GS21-23P0 please?
220V 2.2kw Spindle

 

 

Relevant manual pages attached.

Thanks in advance!

Thanks

That looks correct for SINK mode, assuming you can program
DI1 to be RUN/STOP,  DI2 to be FWD/REV and frequency
command from analog 0-10V input

I think this is P3.01 = 1 and P4.00 = 2

Yes, correct.
DI1 = Digital Input 1 = FORWARD
DI2 = Digital Input 2 = REVERSE

You need to set DI1 to RUN and DI2 to FWD/REV to work with the 7I76E
I think this is P3.01 = 1

This doesn't work and I suspect that your Parameters may be incorrect.
Manual located here .
Thanks for your feedback though.

Ah... different GS2, this should be correct:

P00.20 = 2 Frequency command from analog input
P02.00 = 1 DI1 = RUN/STOP DI2 = FWD/REV

I am still not clear on this issue.

My spindle runs in reverse when the Durapulse VFD indicates Forward.

And I am getting an error Elo1 over voltage, likely caused by the above.

My spindle runs in reverse when the Durapulse VFD indicates Forward.

Change ONLY two of the motor wires.
Do unplug the VFD before doing this.

Elo1 over voltage is normally caused by too fast of a decel ramp or lack of a breaking resistor.

Look at this, it may help.

The acceleration time determines the time required for the AC motor drive to ramp from 0.00 Hz to
the maximum operation frequency (P01.00). The deceleration time determines the time required
for the AC motor drive to decelerate from the maximum operation frequency (P01.00) down to
0.00 Hz.

The acceleration and deceleration time are invalid when using P0144 Auto-acceleration and
Auto-deceleration Setting

Select the Acceleration/Deceleration Time 1, 2, 3, 4 with the multi-function input terminal settings
The defaults are Acceleration Time 1 and Deceleration Time 1

With the enabled torque limits and stall prevention functions, the actual acceleration and
deceleration time are longer than the above action time

Note that setting the acceleration and deceleration time too short may trigger the drive’s
protection function (P0603 Over-current Stall Prevention during Acceleration or P0601
Over-voltage Stall Prevention), and the actual acceleration and deceleration time are longer than
this setting

Note that setting the acceleration time too short may cause motor damage or trigger drive
protection due to over-current during the drive’s acceleration

Note that setting the deceleration time too short may cause motor damage or trigger drive
protection due to over-current during the drive’s deceleration or over-voltage

Use suitable braking resistors (refer to Appendix A: Accessories) to decelerate in a short time and
prevent over-voltage

When you enable P0124–P0127 (S-curve acceleration and deceleration begin and arrival time),
the actual acceleration and deceleration time are longer than the setting
