Emergency Stop mode
When the rotary indexing table is operating in normal mode (start from the base
position) the moment of inertia created is gently accelerated via the cam drive and
decelerates. During an emergency stop the rotary table is stopped in the indexing
phase via the motor brake or accelerated after this via the three-phase motor. This
causes excessive acceleration.
This leads to an increased load of the driving elements and thus to a reduced
service life.
In order to reduce this torque peak we would suggest adopting the following
measures:

Extension of the indexing time or reduction in the moment of inertia.

Use of a frequency converter for a soft start at creeping speed after
emergency stop up to the next base position.

Use of a pole-changeable motor.
Jog mode in the nominal speed of the drive motor is not
permitted.
If jog mode is required, a pole-changeable motor or a
frequency converter must be used. In the jog mode creeping speed must always be
applied.

The warranty is regulated by contract (see General Terms and Conditions or
