(*) NOTE
The maximum allowable value (as an absolute value) for C028 and C029 (min. and max.
motor speed) also depends on the preset max. carrier frequency (see Table 70). It can
be max. 4 times the rated speed of the connected motor.
NOTE
The value set as the min. speed is used as the saturation of the global reference; the
speed reference will never be lower than the value set as min. speed.
NOTE
The min. speed is not respected only when the REV command or the CW/CCW command
are sent after setting a value for max. speed exceeding the min. value (C029>C028 for
motor 1) and with the max. reference to the drive. The motor rpm will be –C029 <C028.
C029 (C072, C115) Max. Motor Speed
C072 (Motor 2)
Range
0 ÷
parameter C028)
0 ÷ 32000 rpm (*see note in parameter C028)
Function
This parameter defines the maximum speed of the connected motor. When
references forming the global reference are at their max. relative value, the global
reference equals the max. speed of the connected motor.
If C011 (C054, C097) = 2: Torque with speed limit,
this parameter is used to limit
the motor rotation.
NOTE
In the CONTROL METHOD MENU, if an external speed/torque limit source (C147) is selected,
the speed limit value set with this parameter is the upper limit, that can be reduced by adjusting
the external source. Also, the ramp times set in the RAMPS MENU (P009–P025
) are applied to
this limit.
C030 (C073, C116) Field weakening Start Speed
C073 (mot. n.2)
Range
0 ÷ 200 0: Disabled ÷ 200%
Function
This parameter defines the speed value determining the motor field weakening
based on 1/n (“static” field weakening).
It is expressed as a percentage of the rated motor speed C016 (C059, C102).
With C030 (C073, C116)=0: Disabled, the motor field weakening
based on law 1/n.
For more details, see Field Weakening (VTC and FOC Only).
