Functional Description
Motor Data and Controller Adjustment
With CS.23 all of the controller functions are activated/deactivated.
CS.23 Function
0
Controller off, inverter performs according to U/f-characteristic (controlled)
1
Controller on
This means: If the parameterizing of an inverter is done e.g. at a system input voltage
of 400 V, while the drive operates later on a 460 V system, then either parameter
Fr.10 = 2 must be written again or the inverter must already be parameterized on the
400V-system by means of dS.10 = 460V and Fr.10 = 1 for the 460 V system.

Controller
Activation
(CS.23)
The controlled operation is suited only as emergency operation for set up or in case
of a faulty encoder.
Increased oscillating torque compared to controlled operation.
Continues to indicate the actual speed measured by encoder 1.
Active current and actual torque are internally set to zero, i.e. ru.2 and ru.10 always
display the value 0. If outputs are programmed to torque-dependent switching or if a
torque signal is given out over an analog output then the outputs behave like they do
at actual torque/active current = 0.
Indicates the actual output frequency converted into min
-1
ru.4 =
x 60
Serve for the calculation of the pole pair number, for that reason they must be adjusted
correctly even in controlled operation.
Define the voltage/frequency-characteristic.
If the speed control is deactivated then all torque limits are without effect.
Are without function in controlled operation. speed and flow controller are not active.
Only dS.10 (voltage stabilization) and dS.11 (Boost) are still effective.
The controlled operation can be activated in the synchronous module (Pc.0 = on)
and the positioning module (Pd.0 = on). The positioning (Pd.0 = on) or synchronous
control
(Sn.0 = on) should be activated only at switched on speed control, otherwise the
positioning control is very instable.
