Parameter Name and Description
152
E C v2
Selects amount of droop that the speed
reference is reduced when at full load torque.
Zero disables the droop function.
Setting parameter 080 to 0 is recommended
when you are using the Droop function.
153
E C v2
Sets the maximum power limit transfer from
FV
the motor to the DC bus. When you are using an
external dynamic brake, set this parameter to its
minimum
(–800.0%) value. Overvoltage trips can occur if
set too negative and the connected brake is
unable to dissipate the energy.
154
E C v2
Sets the largest rate of change for the current
FV
reference signal. This number is scaled in
percent of maximum motor current every 250
microseconds.
189
E C
Sets the time that the drive is at or above
current limit before a fault occurs. Zero disables
this feature.
145
E C
Enables/disables dynamic brake operation.
Disabled = DB operates only when the drive is
running.
Enable = DB operates whenever the drive is
energized.
155
Standard
156
Standard
Active stop mode. [Stop Mode A] is active unless
[Stop Mode B] is selected by digital inputs that
are programmed for "Stop Mode B."
