100 Unidrive M / HS Frame 7 to 10 Power Installation Guide
Issue Number: 5
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: 18 g, 6 ms, 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.
Sinusoidal Vibration Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard: IEC 60068-2-6: Test Fc:
Frequency range: 5 to 500 Hz
Severity: 3.5 mm peak displacement from 5 to 9 Hz
10 m/s² peak acceleration from 9 to 200 Hz
15 m/s² peak acceleration from 200 to 500 Hz
Sweep rate: 1 octave/minute
Duration: 15 minutes in each of 3 mutually perpendicular axes.
EN 61800-5-1:2007, Section 5.2.6.4. referring to IEC 60068-2-6
Frequency range: 10 to 150 Hz
Amplitude: 10 to 57 Hz at 0.075 mm pk
57 to 150 Hz at 1g p
Sweep rate: 1 octave/minute
Duration: 10 sweep cycles per axis in each of 3 mutually perpendicular axes
5.1.13 Starts per hour
By electronic control: unlimited
By interrupting the AC supply: ≤20 (equally spaced)
5.1.14 Start up time
This is the time taken from the moment of applying power to the drive, to the drive being ready to run
the motor:
Size 7 to 10: 5s
For faster start up time a 24V backup supply can be used, see section 4.4 24 Vdc supply on page 59
5.1.15 Output frequency / speed range
Unidrive Mxxx models:
In all operating modes (Open loop, RFC-A, RFC-S) the maximum output frequency is limited to 550
Hz.
Unidrive HSxx models:
In open loop mode the maximum achievable output frequency is 3,000 Hz.
In RFC-A and RFC-S modes, the maximum achievable output frequency is 1,250Hz.
