DESCRIPTION OF PROGRAMMING PARAMETERS
Cn.36
Initial pole
position
estimation
interval
20ms 1 – 100ms
It allows adjusting the time interval between
retries to estimate the initial position of the
pole in a permanent magnet synchronous
motor (PM).
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.37
Initial pole
position
estimation
pulse current
(%)
15%
10 –
100%
It allows adjusting the value of the current
pulse in the estimation of the initial position
of the pole in a permanent magnet
synchronous motor (PM).
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.38
Initial pole
position
estimation
pulse voltage
(%)
500%
100 –
4000
It allows adjusting the value of the voltage
pulse in the estimation of the initial position
of the pole in a permanent magnet
synchronous motor (PM).
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.39
PM dead-time
range (%)
100.0%
50.0 –
200.0%
Sets the output compensation values during
the operation of a permanent magnet
synchronous motor in sensorless vector
control mode. If the motor does not run at
low speeds, at 5%, or less, of the rated
motor speed, increase the values in 10%
increments. Decrease the values by 10%
decrements if a clanking noise occurs at
motor startup and motor stop.
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.40
PM dead-time
voltage (%)
100.0%
50.0 –
200.0%
Cn.41
PM speed
estimator
proportional
gain
100 0 – 32000
Establish the values of the gain of the speed
estimator during the operation of a
permanent magnet synchronous motor in
sensorless vector control mode. If there is a
fault or the motor vibrates at low speed,
decrease this parameter by 10%
decrements until the motor runs correctly.
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
