General safety information
Please observe the following safety instructions and application notes to preserve the
certified safety engineering features and to ensure trouble−free and safe operation.
Residual hazards
In case of a short−circuit of 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 °)
This residual movement must be considered in the risk analysis, e.g. safe torque off for main
spindle drives.
