7.6.1.4 Test conditions
The entire safety circuit must be tested for functionality.
The function test is performed from the following start condition:
•
An operation-ready servo drive system
•
Safe input ENABLE_L is LOW and ENABLE_H is HIGH
•
Software application is running
•
Motor(s) running
Depending on the wiring:
1. both the ENABLE_L and ENABLE_H inputs are opened
or when ENABLE_L is connected to
„Ext. GND“ and the safe output of a Safe PLC is
used for ENABLE_H,
2. ENABLE_H is open or LOW (depending on the wiring).
The motor speed is expected to slow to null and the relay output S1/S2 to close after a
minimum delay of 0.4 s and a maximum of 1 s when the servo drive is supplied with 24 V.
The servo drive system should go into safe mode.
