Re: Actualizacion EMCO VCM 300
Have you let the drive go through its self tune procedure to characterize the motor? This motor appears to be an induction motor, are you running the drive in induction motor mode? Honestly, I am going to keep saying it... You need to start diagnosing the problem. There is probably no-one that can m...

Re: Actualizacion EMCO VCM 300
I just went through the delta web site for support.
How sure are you that your motor is set up correctly induction/permanent magnet motor and all the parameters are correct. Encoder and resolver all wired correctly and in phase?

Re: Actualizacion EMCO VCM 300
Just search usb rs-485 and you will find heaps of options. Then just cut up an old ethernet cable and wire it to it. Braking resistors dont get very hot. They take a lot of repeated stops to get really hot What is the exact error code so I can look it up in the manual. Not sure about using automatic...

Re: Actualizacion EMCO VCM 300
The motor driver takes the AC mains and converts it to DC on its internal bus. Then it converts that DC to the driving AC for the motor at whatever frequency is required. During deceleration, the motor acts like a generator making AC. The drive converts that AC to DC current on to its internal bus. ...

Re: Actualizacion EMCO VCM 300
From memory, my motor is 8 pole so requires twice the frequency for the same RPM.

Re: Actualizacion EMCO VCM 300
RPM = Hz x 120 / num poles = 272 x 120 / 4 = 8160 RPM
If you are getting over current then the resistance is probably too low. Stick within the value recommended by the book.
This motor must have a lot of rotating inertia to be that hard to slow down!
Either put

Re: Actualizacion EMCO VCM 300
There is no recommended value. It depends on the motor and drive. But, if you cant even get down to 10 seconds then something needs sorting. I think it's time to show the actual fault you are having and what is going on in practice. Use VFD soft to record some traces of the motor current, RPM and DC...

Re: Actualizacion EMCO VCM 300
10 seconds is the default value. I think it is the time to go from rated rpm to zero. Are you sure the VFD is configured correctly for your motor? Does the motor do the same RPM as the VFD shows? Settings things like the number of poles incorrectly would cause a major issue. Are you sure that you ha...

Re: Actualizacion EMCO VCM 300
In the manual you will need to refer to settings PR 06-01 to 06-05. Also PR 07-00 to PR 07-04. Search "braking", "brake" and "decel" in the manual. PR 01-12 and 01-13 set the accel and decel times. I use 0.35s but my motor is smaller. 3s is a good starting point, then g...

Re: Actualizacion EMCO VCM 300
You need to enable the active braking. Otherwise it defaults to internal braking. Putting a DC multimeter across the resistor wires during a braking cycle will tell you if it is dumping into the resistor. Use a meter with 1000V DC rating. Install it where you dont need to be holding it in place. Be ...
