6.7.2 Behavior in the event of an error (with standard setting)
The behavior of the servo amplifier always depends on the current setting of a number of
different parameters (ACTFAULT, VBUSMIN, VELO, STOPMODE, etc.; see online help
).
CAUTION
Some faults (see ERRCODE ) force the output stage to switch-off
immediately, independent from the ACTFAULT
setting. Danger of injury
by uncontrolled coasting of the load. An additional mechanical brake is
required for functional safety, which must be safely operated.
The diagram shows the startup procedure and the procedure that the internal control
system follows in the event of motor overtemperature, assuming that the standard param-
eter settings apply. Fault F06 does not switch-off the output stage immediately, with
ACTFAULT=1 a controlled emergency brake is started first.
(F06 = error messages "Motor Temperature")
Even if there is no intervention from an external control system (in the example, the
ENABLE signal remains active), the motor is immediately braked using the emergency
stop ramp if the error is detected and assuming that no changes have been made to the
factory setting (ACTFAULT=1).
