13 Technical Data
13.1 Drive technical data
13.1.1 Power and current ratings (Derating for switching frequency)
13.1.2 Typical pulse duty
The following tables give examples of load profiles that indicate the performance of the drive.
The profiles simulate the drive accelerating from standstill to full speed.
13.1.3 Repetitive profile with defined level of I
peak
Figure 13-1 Repetitive profile with defined level of I
peak
This is a profile with acceleration/deceleration periods where the peak output current from the drive (I
peak
) is given as a proportion of the nominal
current (I
n
) for a defined period of time. (T
peak
).
For example accelerating/decelerating for 10 s with a current of 2.0 x I
n
.
The ratio between accelerating/decelerating period (T
peak
) and the total profile period (T
duty
) is always 1:10.
The profile shows the level of current that can be provided during the running/stopped period when the maximum peak current is used for
accelerating/decelerating.
I
base
is the drive output current during the constant speed segment of the profile.
