The motor is Baumüller servo, original as it was on this Reis RV6 robot.
The original drive has 10A writing on it.
Specs from the servo motor nameplate:
Type = DSG 56-M
3.6kW
S = 3-40%
4000 1/min
I0 = 16.6A
M0 = 7Nm
Most similar motor specs are on page 29 of this document (page 31 of pdf):
What does zero mean near current symbol I?
I will try your suggestions first, but what could I do in case they will
not help:
1. change the ratio of mechanical reducer (I don't need max speeds)
2. rewind the motor (?)
3. take another servo amplifier.
