1)

Valid for devices with firmware versions beginning up from V2.12 2018/03:

V/f-operation:

Output frequency max. 599 Hz

Closed control loop operation:

Speed setpoint values are limited to 30000 rpm. The actual speed value is monitored for the maximum speed of 30000 rpm. Actual speed values are detected above 30000 rpm. The drive generates the error 2319 'n > nmax 'and runs down.

2)

The max. duration of power output current Imax is lowered in DC operation (moving on block/stop). The limit speed between normal and DC operation can be defined using the following formula.

Additional information: Note on application No. AP 2008_05-1d

 

 

The maximum duration of peak output current lmax is based on twice the output power of the inverter. The maximum duratin of power current output tmax can be calculated for any output current. The I2t constant is c = 30 at tmax = 10 s and c = 1.5 at tmax = 0.5 s.

 

 

Formula: Any I2t constant c

 

Additionally, the evaluation of the temperature of the rear panel of the module and the temperature model (KW-R06) provide the best possible protection for the module in DC operation (moving on block) and during cyclic overload with simultaneous high basic load.
