The resultant value is displayed in r1084 (resultant maximum frequency).
Note: When using the setpoint source
• Analog Input
• USS
• Fieldbus
the setpoint frequency (in Hz) is cyclically calculated using
• a percentage value(e.g. for the analog input r0754)
• a hexadecimal value (e.g. for the USS r2018[1])
• and the reference frequency P2000.
If for example P1082 = 80 Hz, P2000 = 50 Hz and the analog input is parameterised with P0757 = 0 V, P0758 = 0
%, P0759 = 10 V, P0760 = 100 %, a setpoint frequency of 50 Hz will be applied at 10 V of the analog input.
Regeneration at rated frequncy is only possible, when the maximum frequency (p1082) is higher than the rated fre-
quency of the motor.
When Quick Commissioning is carried out P2000 is changed as follows: P2000 = P1082.
Description: Displays resultant maximum frequency.
