Functional description

If the restart lock -AS- is not needed, then the input AS-ENABLE must be connected
directly with +24VDC. The restart lock is then passed by and cannot not be used.
In case of use of the restart lock the input AS Enable must be connected to the exit of
a security control or a safety relay, which meets at least to the requirements of the
category 3 after EN 954-1 (see the connection diagram on page 81).
Possible states of the servo amplifier in connection with restart lock -AS-:
AS-ENABLE ENABLE
If the restart lock is engaged during operation by separating input AS ENABLE from 24
VDC, the motor runs down out of control and the servo amplifier displays the error F27.
There is no possibility of braking the drive controlled. If a controlled braking before
the use of the restart lock is necessary, the drive must be braked and the input
AS-ENABLE has to be separated from +24 VDC time-delayed.
The restart lock -AS- does not provide an electrical separation from the power
output. If access to the motor power terminals is necessary, the servo amplifier
must be disconnected from mains supply considering the discharging time of the
intermediate circuit.
Since the restart lock is a single-channel system, erroneous engaging will not be recog-
nized. When wiring the input AS-ENABLE within one enclosure it must be paid attention
to the fact that the used cables and the enclosure meet the requirements of EN 60204-1.
If the wiring leads outside the demanded enclosure, the cables must be laid durably
(firmly), and protected from outside damage.
