PR42: L2 undervoltage threshold*
If the mains voltage at L2 falls below the undervoltage threshold stored (with a resolution of 0.1 V) in register
PR42, bit
SW.5 will be set in the status word [
}
42] .
*) The voltages of the three phases are measured with reference to an artificial star point.
PR43: Overload threshold L2
If the current in phase L2 exceeds the overload threshold stored in register PR43 (with a resolution of
0.01 A), the
ESB.0 bit will be set in the extended status byte [ } 31] while the Overload LED will flash at about
5 Hz. If you set the overload threshold in register PR43 below the rated current, the motor can be switched
off early in the event of excessive rated load, in order to prevent damage.
PR44: Underload threshold L2
If the current in phase L2 falls below the underload threshold stored in register PR44 (with a resolution of
0.01 A), the
ESB.1 bit will be set in the extended status byte [ } 31] while the Overload LED will flash at about
2 Hz. If you set the value in register PR44 below the rated load that has been set, then the motor can be
switched off in the event of, for instance, a broken shaft, in order to avoid more serious damage.

PR47: L3 overvoltage threshold*
If the mains voltage at L3 exceeds the overvoltage threshold stored (with a resolution of 0.1 V) in register
PR47, bit
SW.9 will be set in the status word [
}
42] .
*) The voltages of the three phases are measured with reference to an artificial star point.
PR48: L3 undervoltage threshold*
If the mains voltage at L3 falls below the undervoltage threshold stored (with a resolution of 0.1 V) in register
PR48, bit
SW.6 will be set in the status word [ } 42] .
*) The voltages of the three phases are measured with reference to an artificial star point.
PR49: Overload threshold L3
If the current in phase L3 exceeds the overload threshold stored in register PR49 (with a resolution of
0.01 A), the
ESB.0 bit will be set in the extended status byte [
}
31] while the Overload LED will flash at about
5 Hz. If you set the overload threshold in register PR49 below the rated current, the motor can be switched
off early in the event of excessive rated load, in order to prevent damage.
PR50: Underload threshold L3
If the current in phase L3 falls below the underload threshold stored in register PR50 (with a resolution of
0.01 A), the
ESB.1 bit will be set in the extended status byte [
}
31] while the Overload LED will flash at about
2 Hz. If you set the value in register PR50 below the rated load that has been set, then the motor can be
switched off in the event of, for instance, a broken shaft, in order to avoid more serious damage.
PR51: Maximum permissible current difference
If the current difference between two phases exceeds the value stored in register PR51 (with a resolution of
0.01 A) then bit
SW.0 is set in the status word [
}
42] .
