Maybe you need to tweak the V/F  settings to have lower (than it is at the
moment) voltage at higher speeds?

[Emc-users] XSY inverters (VFD)

[Jon Elson]

Does anybody know the XSY Inverters?

I have an XSY-AT1 Inverter (VFD) and I have it mostly 
programmed just fine.  To get good torque at lower speeds, I 
turned up parameter P72 (Torque compensation setting) and 
that worked great at the lowest speeds.  But, at higher 
speeds, the motor current was too high abnd caused it to 
trip the overcurrent protection (Err 6).  Maybe I did not 
set the overload current setting.  Is that P78 for general 
overload?  P78 - P85 are different overload settings, not 
clear which applies.


Also, P60 is listed as Multifunction input 2 / Idem (relay 
output) default = 0.  This is pretty cryptic.  Is there a 
setting for this that will switch the relay when an error 
condition is detected?


Thanks much in advance for any tips on this drive.

Jon

Thanks for any help,

I found out that the power supply is OK. I was just not getting a good 
connection between my multimeter probes and the PSupply.  I tested at the 
drives and the voltage was good.

I put a new copy of my .ini and .hal file on pastebin.

I am having a horrible time getting this set up right. The 7i76e is an early 
one that Pete gave me to replace one that I burnt up plugging a 12v power 
supply into the 5V connector. Can somebody look at my .ini and .hal files and 
see if they spot anything obviously wrong.

When I run pncconf I can’t get the motors to move. Here is a picture of the 
pncconf screen for the stepper setup using the 7i76e and a picture of the 
pncconf setup for myCNCLathe using the 5i25/7i76 comb.
