12.1.5 Motor requirements
No. of phases: 3
Maximum voltage:
Affinity (200V): 240V
Affinity (400V): 480V
Affinity (575V): 575V
Affinity (690V): 690V
12.1.6 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 the following ambient
temperatures:
>40°C (104°F) - Size 1 to 6 standard drive and size 1 to 3 E12/
E54 drive
>35°C (95°F) - Size 4 to 6 E12/E54 drive
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)
12.1.7 Storage
-40
o
C (-40
o
F) to +50
o
C (122
o
F) for long term storage, or to +70°C
(158°F) for short term storage.
Storage time is two years.
Electrolytic capacitors in any electronic product have a storage period
after which they require reforming or replacing.
The DC bus capacitors have a storage period of ten years.
The low voltage capacitors on the control supplies typically have a
storage period of two years and are thus the limiting factor.
Low voltage capacitors cannot be reformed due to their location in the
circuit and thus may require replacing if the drive is stored for a period of
two years or greater without power being applied.
It is therefore recommended that drives are powered up for a minimum
of one hour after every two years of storage.
This process allows the drive to be stored for a further two years.
12.1.8 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%.
12.1.9 Environmental Protection Rating
The standard drives are rated to IP20/NEMA1. Drive sizes 1 to 3
conform to UL Type 1 and sizes 4 to 6 are Open Class. If the optional
conduit box is installed (see section 3.5
then sizes 4 to 6 conform to UL Type 1.
The E12/E54 drives are rated to IP54/NEMA12 and conform to UL
Type 12.
The E12/E66 drives are rated to IP66/NEMA12 and conform to UL Type
12.
The standard drive can be configured to increase its protection rating to
IP54/NEMA 12 for through-panel mounting (refer to section
3.8
Enclosing standard drive for high environmental protection
page 50).
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 Table 12-16.
Table 12-16 IP Rating degrees of protection
Table 12-17 UL / NEMA enclosure ratings
12.1.10 Corrosive gasses
Concentrations of corrosive gases must not exceed the levels given in:
•
Table A2 of EN 50178
•
Class 3C2 of IEC 60721-3-3
This corresponds to the levels typical of urban areas with industrial
activities and/or heavy traffic, but not in the immediate neighborhood of
industrial sources with chemical emissions.
12.1.11 Vibration
Maximum recommended continuous vibration level 0.14 g r.m.s. broad-
band 5 to 200 Hz.
This is the limit for broad-band (random) vibration. Narrow-band
vibration at this level which coincides with a structural resonance could
result in premature failure.
Bump Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard:IEC 60068-2-29: Test Eb:
Severity: 18g (size 1 to 3), 6ms, half sine
10g (size 4 to 6), 6ms, half sine
No. of Bumps: 600 (100 in each direction of each axis)
Random Vibration Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard:IEC 60068-2-64: Test Fh:
Severity: 1.0 m²/s³ (0.01 g²/Hz) ASD from 5 to 20 Hz
-3 dB/octave from 20 to 200 Hz
Duration: 30 minutes in each of 3 mutually perpendicular axes.
