NOTE:
The value set here can be undershot by a smaller value in P536.
With smaller output frequencies (<4.5 Hz) or higher pulse frequencies (>6 kHz
or 8 kHz, P504) the pulse switch-off can be undershot by the power reduction
(chapter 8.4).
NOTE:
If the pulse switch-off is disabled (P537=201) and a high pulse frequency is
selected in parameter P504, the FI automatically reduces the pulse frequency
when the power limit is reached. If the load on the FI is reduced again, the
pulse frequency increases back to the original value.

With this protective function the output current at the U-V-W terminals is monitored and checked
for plausibility. In case of error, error message E016 is output.
Settings 0 – 3 are identical to settings 4 – 7, however with the settings 4 – 7 a mechanical brake
is not monitored (only relevant for equipment code “-BWRN”).
0 =
Mech. brake:
Only the mechanical brake is monitored.
1 =
Mech. brake + motor phases:
In addition to monitoring of the mechanical brake, the
output current is measured and checked for symmetry. If an asymmetry is present, the FI
switches off and outputs error message E016.
2 =
Mech. brake + excitation.:
In addition to monitoring of the mechanical brake, the excitation
current (field current) is checked when the FI is switched on. If insufficient excitation current
is present, the FI switches off with the error message E016. A motor brake is not released
in this phase.
3 =
MBr.+Motorph. + Magnet.:
In addition to monitoring of the mechanical brake, the motor
phases and excitation are monitored - as 1 and 2 combined.
4 =
Switched off:
Monitoring is not performed.
5 =
Motor phases only:
The output current is measured and checked for symmetry. If an
asymmetry is present, the FI switches off and outputs error message E016.
6 =
Magnetisation only:
When the FI is switched on, the level of the excitation current (field
current) is checked. If insufficient excitation current is present, the FI switches off with the
error message E016. A motor brake is not released in this phase.
7 =
Motor phase + Magnet.:
Motor phase and excitation monitoring, as 5 and 6 combined.
NOTE:
This function can be used as an additional protective function for lifting
applications, but is not permissible on its own as protection for persons.
