Motor Description<br />

1.6 Armature short-circuit braking<br />

1) When utilized acc. to M0 (100 K) a series braking resistor must be used in order to prevent<br />

partial de-magnetization. When utilized according to M0 (60 K), the additional braking resistor<br />

is not required.<br />

2) It is absolutely prohibited to short-circuit the winding when using smaller supplementary<br />

resistors than those specified. When braking from the rated speed, the resistors listed<br />

prevent partial de-magnetization of the rotor.<br />
