□ From the motor
overload
After exceeding the motor overload Thermal integral MT [33] (page 24) beyond the 90%
value, power will be restricted.
□ From external
temperature
After exceeding the temperature ETP Temperature [869] (page 23) evaluated from an
external temperature sensor, power will be restricted.
□ From the power
restriction signal
Converter power restriction after exceeding the parameter value PR Signal [1088] (page
75) beyond the value PR signal limit [1089] (page 75).
PR Signal [1088]
Selection of the signal, according to which the power will be restricted by
an active selection of the power restriction source Power restriction (PR)

PR signal limit
[1089]
Signal limit PR Signal [1088] (page 75), beyond which the converter
restricts the power.

PR controller works only when using the PR source active selection from the power
restriction signal. If the proportional gain is negative, then regulation error is inverted.
I gain PR [1091]
Integration time constant value of the power restriction (PR) controllers
proportional term.
1,00 s
0,00 s ÷ 1000,00 s
PR controller works only when using the PR source active selection from the power
restriction signal.

BIN
HW
Type [172]
Binary inputs hardware evaluation setting. The evaluation covers all digital inputs
simultaneously.
24V Level
0V Level
Individual binary inputs X1:1, X1:2, X1:3, X1:4, X1:5, X1:6 are active when 0V voltage is
connected (Terminal X1:10).
24V Level
Individual binary inputs X1:1, X1:2, X1:3, X1:4, X1:5, X1:6 are active when 24V voltage is
connected (Terminal X1:8).
BIN1 Filter

Binary input is switched on when the voltage level defined by parameter BIN HW Type [172]
(page 75) is present longer than the value of this parameter and is switched off when the voltage
is not present longer than the value of this parameter.
BIN1 Logic
[716]
Determines the binary input evaluation mode. Binary input hardware settings need to
be taken into account.
Direct
Direct
If the HW Type is set to 24V, then the BIN is active if there is 24V on the input. If the HW Type is
set to 0V, then the BIN is active on 0V.
Inverted
If the HW Type is set to 24V, then the BIN is active by 0V. If the HW Type is set to 0V, then the
BIN is active by 24V.
