Symbols
Input
I1N
continuous rms input current Output
I2N
continuous rms current. 50% overload is allowed for one minute every ten minutes.
I2,1
maximum (50% overload) current allowed for one minute every ten minutes
min/10min
I2
maximum output current. Available for two seconds at start, otherwise as long as allowed by
max
the drive temperature.
PN
typical motor power. The kilowatt ratings apply to most IEC 4-pole motors. The horsepower
ratings apply to most NEMA 4-pole motors.
Power cable sizes and fuses
Cable dimensioning for rated currents (I1N) is shown in the table below together with the corresponding fuse types for short-
circuit protection of the input power cable. The rated fuse currents given in the table are the maxima for the mentioned fuse
types.
Check that the operating time of the fuse is below 0.5 seconds. The operating time depends on the fuse type, the supply network
impedance as well as the crosssectional area, material and length of the supply cable. In case the 0.5 seconds operating time is
exceeded with the gG or T fuses, ultra rapid (aR) fuses will in most cases reduce the operating time to an acceptable level.
Note: Larger fuses must not be used.
