Select the control mode:
● VF LIN: U/f control with linear characteristic
● VF LIN F: Flux current control (FCC)
● VF QUAD: U/f control with square-law characteristic
● SPD N EN: Sensorless vector control
Select a suitable control mode
U/f control with linear or square-law characteris-
tic
Flux current control (FCC)
Vector control without encoder
Closed-loop con-
trol characteristics
Typical correction time after a speed change:
100 ms … 200 ms
• Typical correc-
tion time after a
load surge:
500 ms
• The control
mode is suitable
to address the
following re-
quirements:
– Motor power
ratings < 45 kW
– Ramp-up time 0 → Rated speed (de-
pendent on the rated motor power):
1 s (0.1 kW) … 10 s (45 kW)
– Applications with increasing load torque
without load surges
• The control mode is insensitive with respect
to inaccurate motor data settings
• Typical correction time after a speed change:
< 100 ms
• Typical correction
time after a load
surge: 200 ms
• The vector control
controls and limits
the motor torque
• Torque accuracy
that can be
achieved: ± 5 % for
15 % … 100 % of
the rated speed
• We recommend vector control for the following
applications:
– Motor power ratings > 11 kW
– For load surges 10 % … >100 % of the rat-
ed motor torque
• The vector control is necessary for a ramp-up
time 0 → Rated speed (dependent on the rated
motor power):
< 1 s (0.1 kW) … < 10 s (250 kW).
• Pumps, fans, and compressors with flow
characteristic
• Pumps and compressors with displacement
machines
Motors that can be
operated
Induction motors Induction, synchronous and reluctance motors
Power Modules
that can be oper-
ated
150 Hz with PM330 Power Module
• Contrary to vector control, no speed control-
ler has to be set
