1.3.3.8 Monitoring reasons for stoppage
This monitoring may, through strategic choice, entail either stoppage or reduced performance for
certain faults related to current.
Variables monitored :
Mean drive current.
Output current (short-circuit).
Dissipater temperature.
Motor temperature.
Ambient temperature.
Overspeed.
No resolver.
Maximum and minimum dc bus voltages.
1.3.3.9 General characteristics of the DIGIVEX Little Drive
Power reduction with altitude
Above 1000 m, service power falls by 1% for every 100 m up
to a maximum altitude of 4000 m
Operating temperature
relative humidity
Normal use: 0 - 40°C
Above 40°C, service power falls by 20% for every 10°C up to
a maximum temperature of 60°C.
The variable speed drive stops when the ambient temperature
exceeds 60°C.
85% (without condensation)
Storage temperature
-30°C to +85°C
Chopping frequency
8 kHz
Current bandwidth
600Hz to -3dB
Speed bandwidth
Up to 200Hz
Minimum speed
Minimum speed 0.05 rpm or 1/8000th of maximum speed
