Note: The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Sets the motor weight.
Dependency: IEC drives (p0100 = 0): unit kg
NEMA drives (p0100 = 1): unit lb
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The parameter influences the thermal 3 mass model of the induction motor.
The parameter is not used for synchronous motors (p0300 = 2xx).
Description: Displays the rated motor starting time.
This time corresponds to the time from standstill up to reaching the motor rated speed and the acceleration with
motor rated torque.
Dependency: Refer to: r0333, p0341, p0342
Description: Sets the excitation build-up time of the motor.
This involves the delay time between enabling the pulses and enabling the ramp-function generator. The induction
motor is magnetized during this time.
Caution: If there is insufficient magnetization under load or if the acceleration rate is too high, then an induction motor can stall
(refer to the note).
Note: The parameter is calculated using p0340 = 1, 3.
For induction motors, the result depends on the rotor time constant (r0384). If this time is excessively reduced, this
can result in an inadequate magnetizing of the induction motor. This is the case if the current limit is reached while
building up magnetizing. For induction motors, the parameter cannot be set to 0 s (internal limit: 0.1 * r0384).
For permanent-magnet synchronous motors and vector control, the value depends on the stator time constant
(r0386). Here, it defines the time to establish the current for encoderless operation immediately after the pulses have
been enabled.
Description: Sets the de-magnetizing time (for induction motors) after the inverter pulses have been canceled.
The inverter pulses cannot be switched in (enabled) within this delay time.
