Description
Def
112 Vector mode advanced motor
data
Only valid when parameter 9903 Motor Control Mode is 0,1, 3.
WARNING! The following parameters are used internally by the drive to provide optimum
possible motor control. Incorrect setting of the parameters can result in poor performance
and unexpected behaviour of the motor. Adjustments should only be carried out by
experienced users who fully understand the functions of the parameters.
11201
MOTOR STATOR
RESISTANCE (Rs)
Motor stator resistance value measured during the autotune.
-
11202
MOTOR ROTOR
RESISTANCE (Rr)
Phase to phase rotor resistance value in ohms.
-
11203
MOTOR STATOR
INDUCTANCE (Lsd)
For induction motors: phase stator inductance value.
-
11204
MOTOR MAGNETISING
CURRENT (Id rms)
For induction motors: magnetizing / no load current. Before Auto-tune, this value is
approximated to 60% of motor rated current (parameter 9906 MOTOR RATED CURRENT),
assuming a motor power factor of 0.8.
-
11205
MOTOR LEAKAGE
COEFFICIENT (Sigma)
Motor leakage inductance coefficient
-
11207
Quick Rs Measurement
Enable
Allows the stator resistance parameter 11201 MOTOR STATOR RESISTANCE to be adapted
during normal operation.

0 : DISABLE
1 : ENABLE
11208
MOTOR PARAMETER
ADAPTATION ENABLE
Allows the stator inductance parameter 11203 MOTOR STATOR INDUCTANCE to be adapted
during normal operation.
-
0 : DISABLE
1 : ENABLE
11209
PULSE WIDTH MINIMUM
LIMIT
This parameter is used to limit the minimum output pulse width, which can be used for long
cable applications. Increasing the value of this parameter will reduce the risk of over-current
trips on long motor cables, but will also reduce the maximum available output motor voltage
for a given input voltage.

Preventing un-authorized parameter editing.
This function can be used to prevent an un-authorized person from changing the drive parameter values; this function is disabled when delivered
from the factory.

Locking Parameter Access
1)
Go to Parameter 1603 (Long Parameter group) and enter in your chosen parameter access code.
2)
Press the button to exit and parameter 1603 will then be hidden and all parameters will be “Read only” (except for Parameter
1602 which will remain “Read Write”.
Unlocking Parameter Access
1)
Enter into Parameter 1602 the same value as 1603 (as chosen in step 1 above).
2)
All parameters will now be “Read Write” and parameter 1603 will become visible and show the value which was originally
programmed as the parameter access code.
3)
To disable this feature set parameter 1603 PARAMETER ACCESS CODE to zero and then 1602 PARAMETER ACCESS UNLOCK to
zero.
