Remedy
Save the parameters in a non-volatile
memory (RAM → ROM). Then switch the
Control Unit power supply off and then
on again.
Determine the reason why the "Safely
limited speed" was exceeded and rectify
the problem.
Acknowledge the fault.
Determine the reason why the "Safely
limited speed" was exceeded and rectify
the problem.
Acknowledge the fault.
Check the braking behavior of the motor
and, if necessary, modify the tolerance
for parameterizing the "safe braking
ramp".
1)
Check the safety function parameters.
Increase the actual value tolerance (see
SectionSetting the gear ratio and
tolerance (Page 124)). Carry out an
acceptance test.
1)
Check the F-DI wiring. Check the safety
function parameter assignment. Carry
out an acceptance test.
1)
Check the speed setpoint from the
control.
Check and, if necessary, modify the SLS
limits.
1)
Check the tolerance for the "SDI"
function and adapt if necessary.
Check the F-DI wiring.
Perform a fail-safe acknowledgement.
