2 Parameters
2.2 List of parameters
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.
The current to excite the induction motor can be limited in p0644.
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.
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 shortened too much, then this can result in an inadequate de-magnetizing of the induction motor and in
an overcurrent condition when the pulses are subsequently enabled (only when the flying restart function is activated
and the motor is rotating).
Description:
Sets the actual system of units for motor equivalent circuit diagram data.
Value:
1:
System of units, physical
2:
System of units, referred
Dependency:
The parameter can only be changed in an offline project using the commissioning software.
Refer to: p0304, p0305, p0310
Note:
The reference parameter for resistances of the rated motor impedance Z = p0304 / (1.732 * p0305) is in the % units
system.
Inductances are converted into a resistance using the factor 2 * Pi * p0310.
If a reference parameter (p0304, p305, p0310) is zero, then it is not possible to make a changeover to "referred"
values (per unit values).
Description:
Sets the stator resistance of the motor at ambient temperature p0625 (phase value).
Dependency:
Refer to: p0625, r1912
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 motor identification routine determines the stator resistance from the total stator resistance minus the cable
resistance (p0352).
