Danger!
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
Þ 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.

Stop!
Before mounting/dismounting, switch off the supply voltage to prevent
electronic modules from damage.
