Note
RESM: reluctance synchronous motor (synchronous reluctance motor)
For bit 01:
Initially, the flux is only established with a low rate of rise when magnetizing the induction motor. The flux setpoint p1570
is reached again at the end of the magnetizing time p0346.
The flux differentiation can be switched out if a significant ripple occurs in the field-generating current setpoint (r0075)
when entering the field weakening range. However, this is not suitable for fast acceleration operations because then,
the flux decays more slowly and the voltage limiting responds.
For bit 02:
The flux build-up control operates during the magnetizing phase p0346 of the induction motor. If it is switched out, a
constant current setpoint is injected and the flux is built up corresponding to the rotor time constant.
For bit 03:
Synchronous-reluctance motor:
Activation of the load-dependent optimum flux characteristic.
For bit 06:
Magnetizing is performed with maximum current (0.9 * r0067). With active identification of the stator resistance (see
p0621) quick magnetizing is internally deactivated and alarm A07416 is displayed. During a flying restart of a rotating
motor (see p1200) no quick magnetizing takes place.
For bit 09:
Synchronous reluctance motor (RESM):
Dynamic increase in the flux setpoint when torque is quickly established.
For bit 10:
Synchronous reluctance motor (RESM):
For load-dependent optimum flux characteristic (p1401.3 = 1) the flux setpoint is increased at low speeds.
For bit 14:
When the function is activated, the following applies:
- the optimum flux is calculated and the power loss is entered for optimization purposes
- the efficiency optimization (p1580) is not active.
It only makes sense to activate this function if the dynamic response requirements of the speed controller are low.
In order to avoid oscillations, if required, the speed controller parameters should be adapted (increase Tn, reduce Kp).
Further, the smoothing time of the flux setpoint filter (p1582) should be increased.
