The device can power any motor which has a lower rating than that for which the drive was designed, provided that the minimum current value
is complied with: Ith = 0.2 x drive In.
For motor ratings slightly higher than that of the drive, check that the current taken does not exceed the continuous output current of the drive.
Connecting motors in parallel
Motor switching is possible with the drive unlocked. The integrated protection in Altivar

The curves opposite define the available continuous torque and transient overtorque
for both self-cooled and force-cooled motors.
The only difference is in the ability of the motor to provide a high continuous torque at
less than half the nominal speed.

(1) For power ratings y 250 W, de-rating is 20% instead of 50% at very low frequencies.
(2) The nominal motor frequency and the maximum output frequency can be adjusted from
0.5 to 400 Hz. The mechanical overspeed capability of the selected motor must be checked with
the manufacturer.
The drive rating must be greater than or equal to the sum of the currents of the
motors to be connected to the drive (In). In this case, it is necessary to provide
external thermal protection for each motor using probes or thermal overload relays.
Use of a motor choke (1) is recommended in the following cases:
When three or more motors are connected in parallel
When the motor cable length (L), including all tap links (L1, L2 to Lx), is longer than
the maximum permitted motor cable length (2)
(1) See References on page 17.
(2) For maximum permitted motor cable length, see page 11.
