IMPORTANT
500 • Output frequency at 0% analog
setpoint
• C10 not active for fixed setpoints or
setpoint selection via c40
500 • Output frequency at 100% analog
setpoint
• C11 is never exceeded
999 • C12 = frequency change 0 Hz...C11
• C13 = frequency change C11...0 Hz
999
• For S-ramp accel/decel, adjust c82
• 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

Reference: setpoint
• As chopper frequency is increased,
motor noise is decreased
• Observe derating in Section 2.2
• Automatic derating to 4 kHz at 1.2 x I
40.0 Change C21 until the motor speed no
longer changes between no load and
maximum load
150 • When the limit value is reached, either
the acceleration time increases or the
output frequency decreases
• When C90 = 2, max setting is 180%
20.0 Accel boost is only active during
acceleration
