Unexpected motor rotation possible
In the event of a short-circuit between two power transistors, a residual
movement of the motor of up to 180 °/number of pole pairs may occur!
(Example.: 4-pole motor ⇒ residual movement max. 180 °/2 = 90 °)
Possible consequences:
ƒ
People may be injured by the machine movements (unexpected start-up).
Protective measures:
ƒ
The residual movement must be considered in the risk analysis, e.g. safe
torque off for main spindle drives.
