CP-Parameter
CP.3 Inverter status
In parameter „inverter status“ the actual operating condition of the frequency inverter is
displayed. In the case of an error the current error message is displayed, even if the display
has already been reset with ENTER (error-LED on the operator is still blinking).
nOP „no Operation“; control release not bridged; modulation switched off; output voltage
= 0 V; drive is not controlled
LS „Low Speed“; no direction of rotation preset; modulation switched off; output
voltage = 0 V; drive is not controlled
FAcc „Forward Acceleration“; drive accelerates with direction of rotation forward
FdEc „Forward Deceleration“; drive decelerates with direction of rotation forward
rAcc „Reverse Acceleration“; drive accelerates with direction of rotation reverse
rdEc „Reverse Deceleration“; drive decelerates with direction of rotation reverse
Fcon „Forward Constant“; drive runs with constant speed and direction of rotation
forward
rcon „Reverse Constant“; drive runs with constant speed and direction of rotation
reverse
Status messages and information about the cause and removal are to be found in the
"Standard- and Interface Operator" Instruction Manual.
CP.17 Voltage stabilization
With this parameter a regulated output voltage in relation to the rated frequency can be
adjusted. For that reason voltage variations at the input as well as in the intermediate circuit
only have a small inuence on the output voltage (U/f-characteristic). The function allows,
among other things, an adaption of the output voltage to special motors.
CP.22 DC braking / Mode
With DC-braking the motor is not decelerated by the ramp. Quick braking is caused by
D.C. voltage, which is applied onto the motor winding. This parameter determines how the
dc-braking is triggered.
Value Activation
0 DC-braking deactivated
1 DC-braking at switch off of the direction of rotation and upon reaching 0 Hz. The
braking time is CP.23 or until the next direction of rotation.
2* DC-braking as soon as setting for the direction of rotation is absent.
3* DC-braking as soon as the direction of rotation changes or is absent.
4* DC-braking at switch off of the direction of rotation and upon reaching 4 Hz.
5* DC-braking when the real frequency falls below 4 Hz and the drives decelerates
6* DC-braking as soon as the set value falls below 4 Hz.
7* DC-braking when input I4 is switched (control board B = „0“)
8 DC-braking as long as input I4 is switched (control board B = „0“)
9 DC-braking after switching on the modulation.
* Braking time depends on the actual frequency.
