Parameter Descriptions
* NAMEPLATE RPM PREF: 27.07 Default: 1420 rpm Range: 0.0 to 30000.0 rpm
This parameter contains the motor nameplate full-load rated speed. This is the motor speed in rpm at base frequency minus full load slip.
* MOTOR CONNECTION PREF: 27.08 Default: 1 Range: See below
This parameter contains the motor nameplate winding connection.
Enumerated Value : Motor Connection
0 : DELTA
1 : STAR
MOTOR POLES PREF: 27.09 Default: 1 Range: See below
This parameter contains the motor nameplate pole-pairs.
Enumerated Value : Motor Poles
0 : 2 pole
1 : 4 pole
2 : 6 pole
3 : 8 pole
4 : 10 pole
5 : 12 pole
POWER FACTOR PREF: 27.10 Default: 0.71 Range: 0.50 to 0.99
This parameter contains the motor nameplate full-load power factor.
OVERLOAD
PREF: 27.11 Default: 2.0
Range : 1.0 to 5.0
This parameter contains the allowable motor overload factor. It is used to match the drive current measurement range to the motor. The drive is set
up so that the
Motor Current x Overload can be measured up to a maximum of 2 x the Drive constant torque current rating.
The OVERLOAD parameter has no effect on the current, inverse time or torque limits.
TOTAL INERTIA PREF: 27.23 Default: 0.0000 kgm
2
Range: 0.0000 to
300.0000 kgm
2
The total inertia of the motor and load. This is used as part of the speed loop Autotune feature.
STATOR RES PREF: 27.14 Default: 1.5907 Ω Range: 0.0000 to 250.0000 Ω
This parameter contains the motor model per-phase stator resistance as determined by Autotune.
