Table 10-13 Output inductor losses @ 40°C (104°F) ambient
For Regen inductor and switching frequency filter inductor losses refer to
section 10.4.1 Regen inductors on page 196 onwards.
10.2 Supply requirements
Voltage:
SPX20X 200V to 240V ±10%
SPX40X 380V to 480V ±10%
SPX50X 500V to 575V ±10%
SPX60X 690V ±10%
Number of phases: 3
Maximum supply imbalance: 2% negative phase sequence (equivalent
to 3% voltage imbalance between phases).
Frequency range: 48 to 65Hz

Drives rated for supply voltages up to 690V are suitable for use with
supply types with neutral or centre grounding i.e. TN-S, TN-C-S, TT
The following supplies are not permitted with Unidrive SP Regen
1. Corner grounded supplies (grounded Delta)
2. Ungrounded supplies (IT) > 575V

10.2.1 DC Bus voltage setpoint
The DC Bus voltage setpoint is user definable through Pr 3.05, this must
be set to 50V above Vac*√2.
10.2.2 Temperature, humidity and cooling method
Ambient temperature operating range:
0°C to 50°C (32°F to 122°F).
Output current derating must be applied at ambient temperatures
>40°C (104°F).
Minimum temperature at power-up:
-15°C (5°F), the supply must be cycled when the drive has warmed
up to 0°C (32°F).
Cooling method: Forced convection
Maximum humidity: 95% non-condensing at 40°C (104°F)
10.2.3 Storage
-40

C (-40

(158°F) for short term storage.
10.2.4 Altitude
Altitude range: 0 to 3,000m (9,900 ft), subject to the following conditions:
1,000m to 3,000m (3,300 ft to 9,900 ft) above sea level: de-rate the
maximum output current from the specified figure by 1% per 100m
(330 ft) above 1,000m (3,300 ft)
For example at 3,000m (9,900ft) the output current of the drive would
have to be de-rated by 20%.
10.2.5 IP Rating (Ingress Protection)
The Unidrive SP is rated to IP20 pollution degree 2 (dry, non-conductive
contamination only) (NEMA 1). However, it is possible to configure the
drive to achieve IP54 rating (NEMA 12) at the rear of the heatsink for
through-panel mounting (some current derating is required).
In order to achieve the high IP rating at the rear of the heatsink with
Unidrive SP size 1 and 2, it is necessary to seal a heatsink vent by fitting
the IP54 insert as shown in the Unidrive SP User Guide. For increased
fan life time in a dirty environment the heatsink fan must be replaced
with an IP54 rated fan on size 1 to 4. Sizes 5 and 6 are fitted with IP54
heatsink fans as standard. Contact the supplier of the drive for details.
Fitting of the IP54 insert and/or IP54 rated fan on sizes 1 and 2 requires
output current derating to be applied, see the Unidrive SP User Guide for
further details.
The IP rating of a product is a measure of protection against ingress and
contact to foreign bodies and water. It is stated as IP XX, where the two
digits (XX) indicate the degree of protection provided as shown in the
Unidrive SP User Guide.
