Example:
• 2-wire control
•
LI1 is assigned to the movement in the right direction
• LI2 is assigned to the movement in the left direction
• The standards EN 954-1 Category 3 and ISO 13849-1 require the use of a stop button with double contact
(S1).
• S1 is used to activate the safety function "power removal".
•
S2 is used to initialize the safety switching device during power up or after an emergency stop. You can
use other initialization conditions of the module via ESC.
• A safety switching device can be used for the safety function "power removal" of multiple ACOPOSinverter
P84 inverters. In this case, the delay must be set in accordance with the longest stop time.
A logic output of the safety switching device can be used to safely indicate that the inverter is operating under
safe conditions.
Note:
For preventive maintenance, the function "power removal" must be activated at least once a year.
Before the preventive maintenance, the supply voltage of the inverter must be switched off and then
back on.
The signals of the logic outputs of the inverter cannot be considered as safety-relevant signals.
Install suppressors in all inductive control circuits that are in the vicinity of the inverter or connected
to the same circuit (relays, contactors, solenoid valves, etc.).
