Requirement
Stopping by immediately swit-
ching off the energy supply of
the machine drive elements
Stop where the energy of the
machine drive elements is
maintained in order to reach a
stop. The energy supply is only
interrupted, if the standstill is
attained.
Stop where the energy to the
machine drive elements is
maintained.

Intended use

The Compax3M drive controller supports the "safe torque off" (STO) safety functi-
on, with protection against unexpected startup according to the requirements of EN
954-1 category 3, EN ISO 13849-1 PL=d and EN 1037.
Together with the external safety control device, the "safe stop 1" (SS1) safety
function according to the requirements of EN 954-1 category 3 can be used. As the
function is however realized with the aid of an individually settable time delay on
the safety switching device, you must take into account that, due to a fault in the
drive system during the active braking phase, the axis trundles to a stop unguidedly
or may even accelerate actively in the worst case until the expiry of the preset
switch-off time.
According to a risk evaluation which must be carried out according to the machine
standard 98/37/EG or EN ISO 12100, EN ISO 13849-1 and EN ISO 14121-1, the
machine manufacturer must project the safety system for the entire machine inclu-
ding all integrated components. This does also include the electrical drives.
When using the S1 option, a protocol describing the orderly working of the safety
function must be made upon the setup and in defined maintenance intervals (see
protocol proposal).
Qualified personnel
Projecting, installation and setup require a detailed understanding of this descripti-
on.
Standards and accident prevention regulation associated with the application must
be known and respected as well as risks, protective and emergency measures.

System be- Remark
haviour
Uncontrolled Uncontrolled stop is the stopping of a machine move-
stop ment by switching off the energy of the machine drive
elements.
Available brakes and/or other mechanical stopping
components are applied.
Controlled Controlled stop is the stopping of a machine movement
stop by for instance resetting the electrical command signal
to zero, as soon as the stop signal has been detected
by the controller, the electrical energy for the machine
drive elements remains however during the stopping
prodecure.
Controlled This category is not covered.
