P0341[3] Motor inertia [kg*m^2] Min: 0.00010
CStat: CUT Datatype: Float Unit: - Def: 0.00180
P-Group: MOTOR Active: Immediately QuickComm.: No Max: 1000.00000
Sets no-load inertia of motor.
Together with P0342 (inertia ratio total/motor) and P1496 (scaling factor acceleration), this value produces
the acceleration torque (r1517), which can be added to any additional torque produced from a BICO source
(P1511), and incorporated in the torque control function.
Index:
P0341[0] : 1st. Drive data set (DDS)
P0341[1] : 2nd. Drive data set (DDS)
P0341[2] : 3rd. Drive data set (DDS)
Note:
The result of P0341 * P0342 is included in the speed controller calculation. P0341 * P0342 (inertia ratio
total/motor) = total motor inertia
P1496 (scaling factor acceleration) = 100 % activates acceleration pre-control for the speed controller and
calculates the torque from P0341 (motor inertia) and P0342 (inertia ratio total/motor).
P0342[3] Total/motor inertia ratio Min: 1.000
CStat: CUT Datatype: Float Unit: - Def: 1.000
P-Group: MOTOR Active: Immediately QuickComm.: No Max: 400.000
Specifies ratio between total inertia (load + motor) and motor inertia.
Index:
P0342[0] : 1st. Drive data set (DDS)
P0342[1] : 2nd. Drive data set (DDS)
P0342[2] : 3rd. Drive data set (DDS)
P0344[3] Motor weight Min: 1.0
CStat: CUT Datatype: Float Unit: kg Def: 9.4
P-Group: MOTOR Active: Immediately QuickComm.: No Max: 6500.0
Specifies motor weight [kg].
Index:
P0344[0] : 1st. Drive data set (DDS)
P0344[1] : 2nd. Drive data set (DDS)
P0344[2] : 3rd. Drive data set (DDS)
Note:
- This value is used in the motor thermal model.
- It is normally calculated automatically from P0340 (motor parameters) but can also be entered
manually.
- Default value is depending on inverter type and its rating data.
r0345[3] Motor start-up time Min: -
Datatype: Float Unit: s Def: -
P-Group: MOTOR Max: -
Displays motor start-up time. This time corresponds to the standardized motor inertia.
The start-up time is the time taken to reach rated motor speed from standstill at acceleration with rated
motor torque (r0333).
Index:
r0345[0] : 1st. Drive data set (DDS)
r0345[1] : 2nd. Drive data set (DDS)
r0345[2] : 3rd. Drive data set (DDS)
P0346[3] Magnetization time Min: 0.000
CStat: CUT Datatype: Float Unit: s Def: 1.000
P-Group: MOTOR Active: Immediately QuickComm.: No Max: 20.000
Sets magnetization time [s], i.e. waiting time between pulse enable and start of ramp-up. Motor
magnetization builds up during this time.
Magnetization time is normally calculated automatically from the motor data and corresponds to the rotor
time constant (r0384).
Index:
P0346[0] : 1st. Drive data set (DDS)
P0346[1] : 2nd. Drive data set (DDS)
P0346[2] : 3rd. Drive data set (DDS)
Note:
- If boost settings are higher than 100 %, magnetization time may be reduced.
- Default value is depending on inverter type and its rating data.
- An excessive reduction of this time can result in insufficient motor magnetization.
