Example 2, IEC:
How to calculate the required drive
If your application requires continuous 12.0 A of motor current (
I
N
) at 8 kHz switching
frequency, the supply voltage is 400 V and the drive is situated at 1500 m altitude and
at 35 °C ambient temperature, calculate the appropriate IP21 / UL Type 1 drive size
requirement as follows:
1.
):
The minimum size required is
I
N
= 12.0 A / 0.65 = 18.46 A,
where 0.65 is the derating for 8 kHz switching frequency (frames R2…R3).
2.
(page
The derating factor for 1500 m is 1 - 1/10 000 m · (1500 - 1000) m = 0.95.
The minimum size required becomes then
I
N
= 18.46 A / 0.95 = 19.43 A.
3.
Ambient temperature derating, IP21 (UL Type 1)
No derating needed for 35 °C ambient temperature.
Referring to
I
N
in the ratings tables (starting from page
), drive type ACH580-01-026A-4
exceeds the
I
N
requirement of 19.43 A.
Example 2, UL (NEC):
How to calculate the required drive
If your application requires continuous maximum current with 10% overload 12.0 A of
motor current (
I
LD
) at 8 kHz switching frequency, the supply voltage is 460 V and the
drive is situated at 4921 ft (1500 m) altitude and at 35 °C ambient temperature,
calculate the appropriate IP21 / UL Type 1 drive size requirement as follows:
1.
):
The minimum size required is
I
LD
= 12.0 A / 0.65 = 18.46 A,
where 0.65 is the derating for 8 kHz switching frequency (frames R2…R3).
1.
(page
The derating factor for 4921 ft (1500 m) is 1 - 1/10 000 m · (1500 - 1000) m =
0.95.
The minimum size required becomes then
I
LD
= 18.46 A / 0.95 = 19.43 A.
1.
Ambient temperature derating, IP21 (UL Type 1)
No derating needed for 35 °C ambient temperature.
Referring to
I
LD
in the ratings tables (starting from page
), drive type ACH580-01-
023A-4 exceeds the
I
LD
requirement of 19.43 A.
