Process values
* Motor current did not exceed the value 1A during the operation
In the figure above, you can see the positive linear frequency ramp-up (10[s] duration) of unloaded
motor from the zero frequency to the setpoint frequency of 50 [Hz]. Ramp-down of the motor is
realised with linear ramp (10[s] duration) to the zero frequency. Compliance with conditions (motor
frequency is greater than 20 [Hz] and motor current <1 [A]) is indicated by the switching of the
current signal from 0 to 20 [mA] on the analog output AOUT1.
The frequency of the
coverter output (Freq.
INV [47])
Output signal 0-20 [mA]
of the analog output AOUT1
(Freq. INV [47] = 20 [Hz])
