7. TECHNICAL DATA
87
NOTE!
The rated currents in given ambient temperatures (in Table 36 The technical data of the N800A AC drive) are
achieved only when the switching frequency
≤ the factory default.
If your process includes a cyclical load, for example if there are lifts or winches, speak to the manufacturer to get
the dimensioning information.
7.1.3 OVERLOAD CAPABILITY
The low overload means that if 110% of the rated continuous current (I
L
) is required for 1 minute every 10 minutes, the remaining
9 minutes must be approximately 98% of I
L
or less.
This is to make sure that the output current is not more than I
L
during the duty cycle.
Fig. 31: Low overload in N800A
The high overload means that if 150% of the rated continuous current (I
H
) is required for 1 minute every 10 minutes, the re-
maining 9 minutes must be approximately 92% of I
H
or less.
This is to make sure that the output current is not more than I
H
during the duty cycle.
