Description, Explanations
Nominal current of motor for speed 1.
Nominal current of motor for speed 2.
Class according to EN/IEC
60947-4-1
Current factor when using an external CT or when the motor wires
are fed through the UMC CTs more than once.
Setting for the built-in PTC (Thermistor) protection. The reaction
to hardware cannot be set separately.
After a thermal overload trip which was triggered through the
thermal motor model the cooling duration can be defined as fixed
time or as a percentage of the thermal load level (0%=cold, 100%
= trip)
The time a restart is inhibited following a thermal overload trip
triggered by the thermal motor model
Below this threshold a motor restart is accepted.
If the thermal model reaches the warning level a warning is
generated.
Current in percentage that should trigger a locked rotor fault
during motor start-up. A value of 800% (160) switches off the
function.
The time the motor current must exceed the adjusted threshold
before a fault is triggered.
Options
0.24...3200A in steps of 0.01A
Default: 0.50A
Unscaled: 24...320000
Example: A value of 24 means
240mA

Examples:
3: motor wires are fed through 3
times
100: internal CT, no multiple
feed-throughs
