166.18 State frequency reduction
166.19 Frequency reduction
Decrease of the frequency in Hz without reduction of the voltage.
166.20 Additional voltage
Additional voltage due to the current control at low frequencies
166.21 Frequency f0
Threshold frequency from which the slope of the voltage is linear. The threshold frequen-
cy is calculated from the Zero voltage (Z166.5–) and the slope of the U-f characteristic.
166.22 Reference frequency
Reference frequency [Hz] = Additional frequency (Z166.23–)
+ Frequency of ramp generator (Z166.24–)
- Frequency reduction (Z166.19–)
166.23 Additional frequency
Additional frequency [Hz] from the compensating controller
Value Meaning
0 Inactive
1 Counter
2 Frequency reduction
3 Increase of frequency with compensating controller for acceleration
4 Voltage reduction
5 Increase of frequency with simple overcurrent protection
