2.2 List of parameters
Description: Display and connector output for signals of the flux channel for a synchronous reluctance motor (RESM).
The values are referred to the rated motor flux of the in-line axis (p0357 * r0331).
Index: [0] = Setpoint before filter
[1] = Optimum flux characteristic output
[2] = Minimum value at low speed
[3] = Dynamic load-dependent boost
[4] = Field weakening value total
[5] = Field weakening value precontrol
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: RESM: reluctance synchronous motor (synchronous reluctance motor)
Description: Sets the flux setpoint referred to rated motor flux.
The following applies for a synchronous reluctance motor:
Scaling the flux setpoint.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
The following applies for a synchronous reluctance motor:
The scaling allows the flux setpoint to be adapted when operating with load-dependent optimum flux characteristic or
with constant flux setpoint.
Description: Sets the flux setpoint referred to rated motor flux.
The following applies for a synchronous reluctance motor:
Scaling the flux setpoint.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0500
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
The following applies for a synchronous reluctance motor:
The scaling allows the flux setpoint to be adapted when operating with load-dependent optimum flux characteristic or
