Hello!

I have a problem with MC_power V5.
When I give MC_Power.enable = TRUE, then
MC_Power.busy is TRUE. but MC_Power.status is still staying FALSE.
and no error and warning are present.
Therefore I cannot start a Jog or other commands. They all give an error 800F, which means the MC_power is not switched on.
Even if I try to use the commissioning panel and push Activate, Enable, then after Enable nothing is happing.

I don't know how to diagnose this, please help

I use TIA Portal V16 
I Have ET200CPU S7-1512F, G120C, and Sick encoder.
G120C and encoder are tested and work well.
I can move the motor via the Sinamics commissioning panel and the encoder measures rotations well.

------------------------------------------------------------------------------------------
Split from MC_Power.Status always 0.

There are diagnostic functions available on the technology object which may be worth looking at.

I am assuming that there is a problem with the signal that gives feedback about the state of the drive's enable. Recheck the configuration of that circuit. 

Make sure that you do a proper download of software hardware.
Do a download and reset if you have to, to make the PLC go through STOP mode.

Hello,
Here are pictures.
DIagnostic show nothing to me.
Seems all is good.

Profidrive telegrams Status word bits are zero.
"Constant velocity" and "acceleration" bits always jump.
Is it good?
I used this tutorial to set up the drive

Hello Pavlan1

How did you solve this problem? We have the same problem.

Kind regards

Hi

Same problem for me. Any idea?

My answer :

We are using a brake resistor. If u follow the wirring instruction, u have to connect the thermal security to DI3.

DI3 is setted to "changing instruction set' (factory defaut). That was my problem.

MCpower telegramm1 use instruction set 1 but my drive was using instruction set2 ....
