F
Min. delay angle for the thyristor firing and the energy transfer from the mains to
the load.
This is the limit for parameter M005 (Alfa) when the drive operates as “motor”.

F
Max. delay angle for the thyristor firing and the energy transfer from the load to
the mains.
This is the limit for parameter M005 (Alfa) when the drive operates as “brake”.

F
This parameter sets the allowable polarity for the UpDownRef internal reference.
See also the MOTOR POTENTIOMETER chapter.
0:Bipolar. Bipolar reference.
1:Positive only. Positive reference only.
2:Negative only. Negative reference only.

F
If set at default value 1:Yes, this parameter restores the last value stored for the
UpDownRef internal reference before or a power failure or the device power off.
Otherwise (0:No setting) this internal reference will always restart from zero. See
also the MOTOR POTENTIOMETER chapter.
0:No. Reset zero value at power on.
1:Yes. Restoration at power on.
