CP.33

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".

CP.29
Setting
Description
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).
Setting
Description
300
The proportional factor of the speed controller is adjusted in these parameters
(see chapter 5 „Start-up").
Setting
Description
100
The integral factor of the speed controller is adjusted in these parameters (see
chapter 5 „Start-up").
Setting
Description
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".
low switching frequency
less inverter heating
less discharge current
less switching losses
less radio interferences
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).
Description
With this parameter the required setpoint source
for torque control can be adjusted.
high switching frequency
less noise development
improved sine-wave simulation
less motor losses
improved controller characteristics
