Set after commissioning: The unloaded
motor should run at approx. slip frequency
(approx. 5 Hz), increase C16 until motor
current (C54) = 0.8 x rated motor current
Set the rated motor frequency (nameplate)
for standard applications

• Output frequency at 100% analog setpoint
• C11 is never exceeded
Frequency change 0 Hz ... C11
Frequency change C11 ... 0 Hz
• Linear characteristic: for standard applications
• Square-law characteristic: for fans and pumps
with square-law load characteristic
• Auto boost: Load-dependent output voltage for
low-loss operation
See C08, selection 7
Reference: setpoint
Automatic derating to 4 kHz at 1.2 x I
r
Change C21 until the motor speed does not drop
any more between no load and maximum load
• When the limit value is reached either the
acceleration time becomes longer or the output
frequency becomes lower.
• If C90 = 2, max setting = 180%
Accel boost is only active during acceleration
Lenze setting: active at E1 = HIGH
