I2t protection

Current limitation in

Fusing

mode

When the amplifier RMS current (I

t) reaches 85% of the Rated current, the Idyn signal output is activated

and the I

t error display flashes on the amplifier front panel. If the RMS current (I

t) has not dropped

below 85 % of the Rated current within 1 second, the I

t default is released and the amplifier is disabled

(otherwise, the Idyn signal and the flashing I

t error display are both eliminated).

When the amplifier RMS current (I

t) reaches the

Rated current

value, the I

t protection limits the

amplifier current to this value.

The amplifier current limitation diagram in an extreme case (motor overload or blocked shaft) is shown
below.

The maximum current duration before the

release

of the Idyn signal depends on the value of the

Rated

current

and

Maximum current

parameters. This value is calculated as follows:

T dyn (second) = t1 - t0 = 200 x

Rated current

(%) /

Maximum current

(%) 2

The maximum current duration before the

limitation

to the rated current also depends on the value of the

Rated current

and

Maximum current

parameters. This value is calculated as follows:

T max (second) = t2 - t0 = 240 x

Rated current

(%) /

Maximum current

(%) 2

NOTE:

When the

Maximum current

Rated current

ratio is close to 1, the values of Tdyn and Tmax

calculated above are below the real values. This formula remains very precise as long as

the Maximum

current

Rated current

ratio is higher than 3/2.

Current limitation in

Limiting

mode (BPCW version 2.0 and amplifier EPROM version 2.4 or greater)

When the amplifier RMS current (I

t) reaches 85% of the

Rated current

, the Idyn signal output is

activated and the I

t error display flashes on the amplifier front panel. When the RMS current (I

t) drops

below 85% of the Rated current, the Idyn signal and the flashing I2t error display are both eliminated.

When the amplifier RMS current (I

t) reaches the

Rated current

value, the I

t protection limits the

amplifier current to this value.

The amplifier current limitation diagram in an extreme case (motor overload or blocked shaft) is shown
below.
