1)
50 % overload is available for one minute every 5 minutes if ambient temperature is less than 25 °C.
If ambient temperature is 40 °C, max. available overload is 37 %.
2)
50 % overload is available for one minute every 5 minutes if ambient temperature is less than 30 °C.
If ambient temperature is 40 °C, max. available overload is 40 %.
3)
50 % overload is available one minute every 5 minutes if ambient temperature is less than 20 °C. If
ambient temperature is 40 °C, max. available overload is 30 %.
4)
50 % overload is available one minute every 5 minutes if ambient temperature is less than 35 °C. If
ambient temperature is 40 °C, max. available overload is 45 %.
Symbols
Sizing
The current ratings are the same regardless of the supply voltage within one voltage range. To achieve
the rated motor power given in the table, the rated current of the drive must be higher than or equal to
the rated motor current.
Note 1: The maximum allowed motor shaft power is limited to 1.5 · P
hd
. If the limit is exceeded, motor
torque and current are automatically restricted. The function protects the input bridge of the drive
against overload.
Note 2: The ratings apply in ambient temperature of 40 °C (104 °F). In lower temperatures the ratings
are higher (except I
max
).
Note 3: Use the DriveSize PC tool for a more accurate dimensioning if the ambient temperature is
below 40 °C (104 °F) or the drive is loaded cyclically.
Nominal ratings
I
cont.max
continuous rms output current. No overload capability at 40 °C.
I
max
maximum output current. Available for 10 s at start, otherwise as long as allowed by drive
temperature.
Typical ratings:
No-overload use
P
cont.max
typical motor power. The power ratings apply to most IEC 34 motors at the nominal voltage,
230 V, 400 V or 500 V.
Light-overload use (10 % overload capability)
I
2N
continuous rms current. 10 % overload is allowed for one minute every 5 minutes.
P
N
typical motor power. The power ratings apply to most IEC 34 motors at the nominal voltage,
230 V, 400 V or 500 V.
Heavy-duty use (50 % overload capability)
I
2hd
continuous rms current. 50 % overload is allowed for one minute every 5 minutes.
P
hd
typical motor power. The power ratings apply to most IEC 34 motors at the nominal voltage,
230 V, 400 V or 500 V.
