Description: Sets the ratio between the total moment of inertia/mass (load + motor) and the intrinsic motor moment of iner-
tia/mass (no load).
Dependency: This means that together with p0341, the rated starting (accelerating time) of the motor is calculated for a vector
drive.
Refer to: p0341, r0345, p1498
Note: SERVO:
p0341 * p0342 + p1498 influence the speed/torque pre-control in sensorless operation.
VECTOR:
The product p0341 * p0342 is taken into account when automatically calculating the speed controller (p0340 = 4).
Description: Sets the ratio between the total force of inertia/mass (load + motor) and the intrinsic motor force of inertia/mass (no
load).
Dependency: This means that together with p0341, the rated starting (accelerating time) of the motor is calculated for a vector
drive.
Refer to: p0341, r0345, p1498
Note: SERVO:
p0341 * p0342 + p1498 influence the velocity/force pre-control in sensorless operation.
VECTOR:
The product p0341 * p0342 is taken into account when automatically calculating the speed controller (p0340 = 4).
Description: Sets the motor weight.
The following applies for vector drives (refer to p0107):
The parameter influences the thermal 3 mass model of the induction motor.
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: The parameter is not used for synchronous motors (p0300 = 2xx).
The parameter is automatically preset for motors from the motor list (p0301).
