In case of 0 Hz, only a load of 62.7 % (≈ 62.5 %) with regard to the load at 40 Hz or above is
possible (69 / 110 * 100 % = 62.7 %). In case of a deviating setting in 0x2D4B:001
(P308.01), the maximum possible motor load changes proportionately.

Motor overload monitoring (i²*t): Maximum
utilisation [60 s]
(Motor overload: Max.load.for 60s)
30 ... [150] ... 200 %
Maximum permissible thermal motor utilisation (max. permissible motor
current for 60 seconds).
100 % ≡ rated motor current 0x6075 (P323.00)
If the motor is actuated with the current set here for 60 seconds, the
maximum permissible thermal motor utilisation is reached and the
response set in 0x2D4B:003 (P308.03) is executed.
If the motor is actuated with a different current, the time period until
the motor overload monitoring function is activated is different.
Generally the following applies: the lower the current, the lower the
thermal utilisation and the later the monitoring function is triggered.

Motor overload monitoring (i²*t): Speed
compensation
(Motor overload: Speed comp.)
Use this function to protect motors that are actuated at a speed below
40 Hz.
UL-compliant operation requires the setting "On [0]"!
0
On
Release time for motor overload monitoring is reduced in order to
compensate for the reduced cooling of naturally ventilated AC induction
motors during operation at low speed.
1
Off
Function deactivated, no reduction of the motor overload monitoring
release time.

Display of the value of the internal i²*t integrator.
37500 ≡ 100 % thermal load
When power is switched off, this value is saved in the internal
EEPROM.
When power is switched on, the saved value is reloaded into the i²*t
integrator.
