The range of this parameter is
1.06
(or
21.01
) plus whatever is added or subtracted by the current limit algorithm and for the
slip compensation.
This parameter gives the output frequency of the drive. This is the sum of the post ramp reference and the slip compensation:
2.01
+ rated slip frequency x
4.02
/ rated active current
2.01
is limited to the maximum frequency defined by
1.06
, plus a margin of 20% to allow the drive to control current
effectively at maximum speed, but the final frequency can exceed this by the slip compensation frequency.
This is the fundamental line voltage at the inverter output.
This is the total output power of the drive. This is calculated from the in phase components of voltage and current such that
the total real output power is measured.
The range of this parameter is calculated by the above equation.
I Max
= 150% of drive rated current
The motor rpm is calculated from the post ramp reference (
2.01
). The speed of rotation is calculated as follows:
rpm
= 60 x frequency / No of pole pairs
= 60 x
2.01
/ (
5.11
/ 2)
The result will be accurate providing the slip compensation has been set up correctly with the rated full load speed parameter
(
5.08
).
However, if
5.11
= 0 (default), the drive calculates the number of poles automatically and so the above equation is not
applicable.
Voltage across the internal DC Bus of the drive
The motor rated frequency is used to define the voltage to frequency characteristic applied to the drive (see
5.09
and
5.14
).
The motor rated current should be set to the machine nameplate value for rated current.
This value is used in the following:
