Hello,
If you are facing E20 fault during declaration, we suggest the below
1. Do factory reset of the parameters typ = 3 and enter. It will change the parameter setting to factory default value.
2. Set the motor nameplate parameters in motor control menu and do a auto-tuning F400 = 2 and give start command. F400 will change to 0 automatically after successful completion of auto-tuning.
If the problem is not solved after above implementing above two suggestions, The E-20 is an over toque boost fault this is similar to a OBF in your case.
Try the following action:
Set the parameter F418 and F419 - follow the programming manual to fine-tune(increase or decrease to optimize) this parameters. Because at first it seems your inertia is very heavy that may be the root cause of your E-20, hence you will have to change this parameter.
if it doesn't work
pt=3
Tuning
put AU1 to 1
increase the DEC ramp.
and modify F418 and F419.
We hope it will help to optimize the torque boost and solve the problem.
