[etherlab-dev] Cannot reset ESC

[Martin Jørgensen]

Hi 

 

I have a big issue trying to reset the ESC from the EtherCAT Master. The ESC is of type BECKHOFF ET1100 and has the following register published:

 

Register ESC Reset ECAT (0x0040)

 

A reset is asserted after writing 0x52 ('R'),

0x45 ('E') and 0x53 ('S') in this register with 3

consecutive frames. 

 

The problem is to send the register writes in 3 consecutive frames. With intermediate frames it doesn't work. The commando tool can send register writes (ethercat reg_write) but these will drop in a register queue and cannot be send in 3 consecutive frames. I have tried to make a small EtherCAT master application, but first of all there is no public interface for sending a register read or write (ecrt.h). Secondly I tried to make a setup where I only did send the etherCAT train after each 'ethercat reg_write ...' but this did not work at all. 

 

Does anyone succeeded in resetting a ESC? 

Is it possible to send 3 consecutive ETherCAT frames from the public interface (ecrt.h), in anyway?

If we need to make an additional reset interface , how to control the 3 consecutive register write ?

 

Any help is highly appreciated.

 

Med venlig hilsen/Best regards,
