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

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

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

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.

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.
