Hello,
Can you please give me the exact formula to get current value of output in dc-servo mode with Kflop+Snapamp ? Is it Value*30/1000, Value*1024/30 or Value*1024/35 or Value*1000/35 ?
Same question regarding th Current variable writen to file data, to get current do we need to do : (Value-8192)*70/16384 or (Value-8192)*60/16384 ?
Thanks !

Hi,
Current command range is 1024 counts corresponds to 35Amps
The current measurement range is 8192 corresponds to 35Amps
HTH

Thanks you very much,
I ahve tried to send a PWM using command line with snapamp+kflop but nothing appear... I have also tried PWMR. Is there a wxay to send a PWM command (or current command - the OUPUT) in open loop ?
Thanks !

The PWM (Voltage), PWMR (Voltage in recirculate mode), and PWMC (Current) commands should work. The Axis should be disabled otherwise the axis will overwrite whatever you set. Is the SnapAmp I'm Alive LED blinking? Is the Fault LED off? Have you set a peak current setting to take SnapAmp out of fault mode?

Thanks I will try to disable axis I can gather the current/position/output/voltage values in command line after the command or do i need to make a C program ?

You can view the currents on the KMotion Analog Screen. Note you must set SnapAmp in the Menu Options.
