Monitoring function - explanations

Phase monitoring - not for axis units
This monitoring function checks the mains voltage of the three outer conductors. If one
outer conductor is missing, then the warning "Phase failure" is reported after a period of
> 4 s.
If all three outer conductors are missing, then the warning "Mains failure" is reported to
the controller after a period of > 4 s. After the preset time lag has been reached (based
on a mains failure monitoring parameter), the controller generates the error message
"Mains failure".
NOTE!
If no electrical filter is used during operation, mains and phase failures are detected
within 100 ms. If the device is operated with an electrical filter, the mains and phase
failures are detected after a max. of 5 s. Depending on the load condition, the failure
can also be detected much earlier, however.
Overcurrent This monitoring function checks whether the motor current is larger than the 1.3 times the
peak output current. This aids "disaster prevention" in case of a short circuit on the output
side.
DC link This monitoring function checks the voltage in the DC link. If the voltage drops below an
internally set value (approx. 50 V under the specified value), the controller reports "DC
link undervoltage" and a warning is signaled. If the voltage rises above an internally set
value (approx. 820 V), the controller reports the error "DC link overvoltage" and a pulse
inhibit takes place immediately.
Overload monitor- This monitoring function checks the present load as to whether the power unit can output
ing the peak current at this time. If the peak current is not possible, then the message "PU
monitoring approached; max. torque current was limited" (warning 206) is reported.
Temperature of This monitoring function checks the temperature in the interior of the device.

If the set temperature threshold 2 is exceeded, then the warning "Temperature threshold

The KTY84 encoder has a minimum measured value of approx. -30 °C. If this tempera-
ture is gone under, or if a short circuit occurs at the encoder, then the error message
"Temperature probe short circuit" is reported.
