Reference/limit frequencies

Min. frequency (entered in Hz)
p1080 = ...
Sets minimum motor frequency [Hz] at which motor will run irrespective of frequency
setpoint. If the setpoint falls below the value of p1080, then the output frequency is set to
p1080 taking into account the sign.
Max. frequency (entered in Hz)
p1082 = ...
Sets maximum motor frequency [Hz] at which motor will run irrespective of the frequency
setpoint. If the setpoint exceeds the value p1082, then the output frequency is limited. The
value set here is valid for both clockwise and anticlockwise rotation.
Reference frequency (entered in Hz)
p2000 = ...
The reference frequency in Hertz corresponds to a value of 100 %.
This setting should be changed if a maximum frequency of higher than 50 Hz is required.
It is automatically changed to 60 Hz if the standard 60 Hz frequency was selected using
p0100.
NOTE
This reference frequency effects the setpoint frequency as both the frequency setpoints via
USS as well as via PROFIBUS (FB100) (4000H hex
Reference voltage (entered in V)
P2001 = ...
The reference voltage in Volt (output voltage) corresponds to a value of 100 %.
NOTE
This setting should only be changed if it is necessary to output the voltage with a different
scaling.
Reference current (entered in A)
P2002 = ...
The reference current in Amps (output current) corresponds to a value of 100 %. Factory
setting = 200 % of the rated motor current (P0305).
NOTE
This setting should only be changed if it is necessary to output the current with a different
scaling.
Reference torque (entered in Nm)
P2003 = ...
The reference torque in Nm corresponds to a value of 100 %. Factory setting = 200 % of
the rated motor torque at a constant motor torque determined from the appropriate motor
data.
NOTE
This setting should only be changed if it is necessary to output the torque with a different
scaling.
