Function Test
The safety function test is required to ensure correct operation. The entire
safety circuit must be tested for full functionality.
Tests must be performed at the following times:
•
After installation
•
In regular intervals, or at least once a year.
If the function test results in an invalid machine status, the error must be found and correct-
ed before the safety function is retested. If the error reoccurs during the function test, the
machine can no longer be operated.
Failure to follow the above safety measures can lead to severe injuries and damage.
Test conditions
The total safety circuit must be tested for functionability
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 if ENABLE_L is connected to "Ext. GND" and the safe output of a Safety 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 1s when the servo drive is supplied with 24 V.
The servo drive system should go into safe mode.
