If the ENABLE_L and ENABLE_H are changed from any status to the "Drive Ready" status,
the servo amplifier is not immediately enabled. In addition, in the software (
K-EN
= 1) or the
corresponding bit in the "control word" must be set so that the software "enable" can be set
and the drive therefore switched to the operational mode
7.6.1.3 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
corrected 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.
