H-80 Function at Stop
Option: Function:
Select the frequency converter function after a stop command or after the speed is ramped down to the
settings in par. H-81 Min Speed for Function at Stop [RPM].
[0] * Coast Leaves motor in free mode.
[1] DC Hold/Motor Preheat Energizes motor with a DC holding current (see par. B-00 DC Hold Current).
P-04 Auto Tune
Option: Function:
The Auto Tune function optimizes dynamic motor performance by automatically optimizing the advanced
motor parameters par. P-30 Stator Resistance (Rs) to par. P-35 Main Reactance (Xh)) while the motor is
stationary.
[0] * Off No function
[1] Full Auto Tune performs Auto Tune of the stator resistance R
S
, the rotor resistance R
r
, the stator leakage reactance X
1
,
the rotor leakage reactance X
2
and the main reactance X
h
.
[2] Reduced Auto Tune performs a reduced Auto Tune of the stator resistance R
s
in the system only. Select this option if an LC
filter is used between the frequency converter and the motor.
Activate the Auto Tune function by pressing [Hand ] after selecting [1] or [2]. After a normal sequence, the display will read: “Press [OK] to finish Auto Tune”. After
pressing the [OK] key the frequency converter is ready for operation.
Note:
• For the best results of the frequency converter, run Auto Tune on a cold motor
• Auto Tune cannot be performed while the motor is running
NB!
It is important to set motor par. P-## Motor Data correctly, since these form part of the Auto Tune algorithm. An Auto Tune must be performed to achieve
optimum dynamic motor performance. It may take up to 10 min., depending on motor power rating.
NB!
Avoid generating external torque during Auto Tune
NB!
If one of the settings in par. P-## Motor Data is changed, par. P-30 Stator Resistance (Rs) to par. P-39 Motor Poles, the advanced motor parameters, will return
to default setting.
This parameter cannot be adjusted while the motor is running
NB!
Full Auto Tune should be run without filter only while reduced Auto Tune should be run with filter.
