5I20 problems with firmware

hi Guys
Have a problem with a 5I20 and 7I48 with loadrt hm2_pci config="firmware=hm2/5i20/SV12IM_2X7I48_72.BIT
PID everything to zero only FF1 = 1
At 500mm / min + 5V -5V
At 250mm / min + 2.5V -7,5V
At 800mm / min + 8V -2V
Cabling is I.O
dmesg :
[ 193.908145 ] RTAI [math ] : loaded .

[ 194.226321 ] hm2 / hm2_5i20.0 : WARNING : upgrade your firmware !
Could this be the problem ??
If so, how do I have to update ??
Have in the packet data management all updates made ​​no success .

The main problem you have is most likely that the PWMGENs are not set to mode 2 (UP/DOWN mode)

The encoder velocity calculation error (which is not related to your voltage output issue) is due to using
a very old firmware file.

You would need to update the hostmot2 firmware package with the package manager to fix this

Hello

I MODE 1 need set + 10V / -10V

Hi have linux 2.7 on it
have made and applied yet this message is an update .

many thanks for the support

Not sure what you are saying about the mode
(PWM gen mode must be set to 2 for the 7I48)

what firmware file are you using?

Firmware Datei ist die SV12IM_2X7I48_72

Mit dem Mode meine ich das ich PWM -Signal +-10V brauche

What I mean is that until you set the PWM mode to mode 2 the +-10V analog output will be incorrect

OK
ie if I need + -10V I have to go suf mode 1 or ?
Can you send me a link where it says how I can update ??

the 7I48 _requires_ that the PWM mode be set to 2
There is no other option that will work

Also if you don't have 2 7I48s you should probably use svst6_6_7i48.bit
its more likely to have been updated

OK then probably comes here purely mode 2

setp hm2_5i20.0.pwmgen.00.output-type 1
setp hm2_5i20.0.pwmgen.00.scale [AXIS_0]OUTPUT_SCALE

But I have 2X7I37TA hang at the 5I20

so
setp hm2_5i20.0.pwmgen.00.output-type 1
must be changed to
setp hm2_5i20.0.pwmgen.00.output-type 2
for all channels

if you have 2 7I37TA, then you should use svst6_6_7i48.bit
