1) When utilized acc. to M0 (100 K), a series braking resistor must be used in order to prevent partial de-magnetiza-
tion.
When utilized according to M0 (60 K), the additional braking resistor is not required.
2) In order to prevent that the motors are de-magnetized, when short-circuit braking from the rated speed, the above
specified supplementary resistors must be connected in series.
