IR COMP VOLT
0…100 V
Sets the IR compensation voltage used for 0 Hz.
• Requires parameter 9904
MOTOR
CTRL
MODE
= 3 (
SCALAR
:
FREQ
).
• Keep IR compensation as low as possible to prevent overheating.
• Typical IR compensation values are:
• When enabled, IR compensation provides an extra voltage boost to
the motor at low speeds. Use IR compensation, for example, in
applications that require a high breakaway torque.
2604
IR COMP FREQ
0…100%
Sets the frequency at which IR compensation is 0 V (in % of motor
frequency).
2605
U/f RATIO
1=LINEAR, 2=SQUARED
Selects the form for the U/f (voltage to frequency) ratio below field
weakening point.
1 =
LINEAR
– Preferred for constant torque applications.
2 =
SQUARED
– Preferred for centrifugal pump and fan applications.
(
SQUARED
is more silent for most operating frequencies.)
2606
SWITCHING FREQ
1, 4, 8, 12 kHz
Sets the switching frequency for the drive.
• Higher switching frequencies mean less noise.
Note:
12 kHz only for frame sizes R1…R4.
