10.1.2 Use as directed
The -AS- restart lock is exclusivelyintended to provide safety for personnel, by preventing the
restart 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 mayonly 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
- longinoperative 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).
