Hi All,
I need your advice on something. I am using AS4.12.5.95 and mappMotion 5.24.1
I’m using a multi-drive and hiperface multiturn sew servo motor, and the machine is working with no any problem.
However, this happens every 4-5 hours, sometimes even more frequently, because one of the servos gives an “amplitude too large” error, and it’s always the same motor giving this error.
The axis that goes into error normally performs absolute positioning back and forth, but the moment the error occurs, the axis starts rotating continuously in one direction at the same speed as when the error occurred, and we can stop it by pressing the emergency stop button and cutting off the drive enable signal.
I don’t have a spare for this motor yet, so I’m wondering if I can increase the limit of the relevant parameter via the driver parameters to prevent the “Amplitude too large” error.
If possible, could you please share the relevant parameter with me?
Thank you in advance.
Hi @hasan_arguc I see one note in the mapp Motion rev history about that error:
I don’t know if your case is exactly what is fixed in the version 5.26.1, but it will be interesting if you can update the motion library and see if you still have the issue.
Ciao
Valerio
Regarding the help, we have a lot of details regarding HIPERFACE card:

Normally when we report similar case to our Support, they suggest to trace few ParIDs to see if SinCos signal is properly detected:
ENCOD_POS_ACT,
ENCOD1_S_ACT,
ENCOD_INC_SIN_AMP,
ENCOD_ADC1,
ENCOD_ADC2 in 200 µs in the error case.
You can trace first those ParIDs with normal movement, without any trigger and force the start, maybe you already see some problems even if the system doesn’t report any issue.
For example you should see at least:
- When Cos signal has min/max value, Sin signal should be 0
- When Sin signal has min/max value, Cos signal should be 0
- Sin and Cos should have same amplitude (max/min value)
