The values must be confirm by „ENTER“.
CP.29 Absolute torque reference
Co-domain
Setting Description
+10000.00 Nm
see 3.3 The absolute torque reference of the drive is adjusted with parameter CP.29 in
torque controlled operation (CP.10 = 5) and with digital setpoint setting (CP.28
= 2). The sign stands for direction of rotation to be active.
In speed controlled operation (CP.10 = 4) the parameter works as torque limit
in all quadrants. The sign has no effect at that.
The factory setting depends on the unit size (see 3.3 „Factory Settings“).
During controlled operation (CP....10) this parameter has no function.
Because of normal type differences and temperature deviations of the motors, tolerances
of up to 30% are possible in the base speed range (see reference on page 13).
CP.30 KP speed
Co-domain
Setting Description
0…32767
300
The proportional factor of the speed controller is adjusted in these parameters
(see chapter 5 „Start-up“).
CP.31 KI speed
Co-domain
Setting Description
0…32767
100
The integral factor of the speed controller is adjusted in these parameters (see
chapter 5 „Start-up“).
CP.32 Switching frequency
Co-domain
Setting
Description
2 / 4 / 8 / 12 / 16 kHz dependend
of the
power
circuit
The switching frequency with which the power modules are clocked can
be changed depending on the application. The employed power stage
determines the maximum switching frequency as well as the factory setting
(see manual:part 2). The values must be confirm by „ENTER“.
Refer to following list to learn
about influences and effects of the
switching frequency.
low switching frequency
high switching frequency
less inverter heating
less noise development
less discharge current
improved sine-wave simulation
less switching losses
less motor losses
less radio interferences
improved controller characteristics
improved concentricity with low
speed (only open loop!)
At switching frequencies above 4 kHz pay absolute attention to the max. motor line length
in the technical data of the power circuit manual (Part 2).
CP.33 Relay output 1 / function
CP.34 Relay output 2 / function
CP.33 and CP.34 determine the function of the two relay outputs (terminals X2A.24…26 and X2A.27…29). The
values must be confirm by „ENTER“.
