Use as directed
The restart lock -AS- is
exclusively
intended to provide safety for personnel, by preventing the res-
tart of a system. To achieve this personnel safety, the wiring of the safety circuits must meet the
safety requirements of EN60204, EN12100 and EN 954-1..
The -AS- restart lock must
only
be activated,
—
when the motor is no longer rotating (setpoint = 0V, speed = 0rpm, enable = 0V).
Drives with a suspended load must have an additional safe mechanical blocking
(e.g. by a motor-holding brake).
—
when the monitoring contacts (KSO1/2) for all servo amplifiers are wired into
the control signal loop.
The -AS- restart lock may
only
be controlled by a CNC if the control of the internal safety relay is
arranged for redundant monitoring.
The -AS- restart lock must
not
be used if the drive is to be made inactive for the following reasons :
1.
- cleaning, maintenance and repair operations
- long inoperative periods
In such cases, the entire system should be disconnected from the supply by the personnel,
and secured (main switch).
2.
- emergency-stop situations
In an emergency-stop situation, the main contactor is switched off (by the emergency-stop
button).
