Programming Parameters
5–56
Minimum Flux Level
[Min Flux Level]
Parameter Number 174
Parameter Type Sink
Display Units x.x%
Drive Units 4096 = 100.0% Flux
Factory Default 100.0%
Minimum Value 12.5%
Maximum Value 100.0%
This parameter sets the smallest level of
flux that will be used to convert a torque to
a current reference. Setting the parameter
to 4096 will prevent flux reduction and by-
pass the torque to current conversion.
Pos Torque Reference Limit
[Pos Mtr Tor Lmt]
Parameter Number 175
Parameter Type Sink
Display Units x.x%
Drive Units 4096 @ rated motor torque
Factory Default 200.0%
Minimum Value 0.0%
Maximum Value 800.0%
This parameter provides a user settable
torque limit for positive torque reference
values. Positive motor torque reference
will not be allowed to exceed this value.
Neg Torque Reference Limit
[Neg Mtr Tor Lmt]
Parameter Number 176
Parameter Type Sink
Display Units – x.x%
Drive Units – 4096 @ rated motor torque
Factory Default – 200.0%
Minimum Value – 800.0%
Maximum Value 0.0 %
Motoring Power Limit
[Motoring Power Lmt]
Parameter Number 177
Parameter Type Sink
Display Units x.x%
Drive Units 4096 @ rated motoring power
Factory Default 200.0%
Minimum Value 0.0 %
Maximum Value 800.0%
This parameter provides for a user entry of
the maximum power level that will be sup-
plied to the motor from the DC bus. The
motoring power limit is used in a calcula-
tion that results in an internal torque limit.
This parameter provides a user settable
torque limit for negative torque reference
values. Negative motor torque reference
will not be allowed to exceed this value.
Regen Power Limit
[Regen. Power Lmt]
Parameter Number 178
Parameter Type Sink
Display Units – x.x%
Drive Units 4096 @ rated regen power
Factory Default – 200.0%
Minimum Value – 800.0%
Maximum Value 0.0%
This parameter provides a user entry for
the maximum power level that will be
transferred from the motor to the DC bus.
Positive Motor Current Reference Limit
[Pos Mtr Cur Lmt]
Parameter Number 179
Parameter Type Sink
Display Units x.x %
Drive Units 4096 @ 100% Motor Current (I
2
)
Factory Default 100.0%
Minimum Value 0.0 %
Maximum Value 200.0%
Negative Motor Current Reference
Limit
[Neg Mtr Cur Lmt]
Parameter Number 180
Parameter Type Sink
Display Units – x.x %
Drive Units 4096 @ 100% Motor Current (I
2
)
Factory Default – 100.0%
Minimum Value – 200.0%
Maximum Value + 0.0%
This parameter specifies the largest allow-
able positive motor Iq axis current that will
be commanded. Bit 0 in Parm 183 indi-
cates when this parameter is actively
restricting Iq current.
This parameter determines the largest
allowable negative motor Iq axis current
that will be commanded. Bit 8 in Parm 183
indicates when this parameter is actively
restricting Iq current.
