Parameter
Description Data Read/write
P354*
Ref Torque
354
Function parameter for entering the reference torque. The
value entered is for normalizing all the torque variables
and corresponds to a connector value of 4000 H (100 %).
The closed-loop control system can process up to twice
the value entered. A value 0 Nm is not allowed.
The reference variable for current (P350) or torque (P354)
should just be changed with the same integer multiple
number. The effective n-regulation will be changed by the
same factor.
Caution:
By changing the set value, the torque limits are changed
as well.

P355*
MachRefSpeed
355
Function parameter for entering the reference speed for
the machine encoder. The entered value is for
normalization of all speed variables of the machine
encoder and corresponds to a connector value of 4000 H
(100%). Values up to twice the input value can be
processed by the control system.
In Index 1 the decimal places of the reference speed
before the comma is entered. If a higher resolution of the
reference speed is required, decimal place after the
comma can be entered in Index 2. Index 2 is only effective
for speed mixing (function diagram 500a). Compare
parameter P353.

P357*
PulseFreqRatio
357
Parameter indicates the ratio of the sampling frequency
(P340) to the pulse frequency.
Parameter values
0 = sampling frequency: pulse frequency = 1:1
1 = sampling frequency: pulse frequency = 2:1
2 = sampling frequency: pulse frequency = 1:2 (for future
use)
P357=2 is only possible at a sampling frequency of
P340=5.0 kHz. (Currently not implemented)
Example: At a sampling frequency of P340=5.0 kHz and
P357=1 a pulse frequency of 2.5 kHz is implemented.
The parameter is automatically set on converters with a
maximum pulse frequency of less than 5 kHz. In the case
of converters with a rating of more than 55 kW and a
maximum pulse frequency of greater than or equal to 5
kHz an additional enable via the PowerExtension PIN
(U977.3-4) is necessary. For power sections > 250 kW
enable via PIN and pulse frequency halving P357=1 are
necessary.
