)
This switch is used to disable/enable the
current regulator inner loop function. It is
used to enhance the current loop
performance.

If RUN LOGIC is selected, the user can
remove the run command and the drive
will delay in dropping the run command
until torque ramp down stop function is
complete.
If EXTERNAL TB or SERIAL is selected,
the user must keep the run command
while allowing the Torque Ramp Down
Stop function to be completed.

S-Curve
Abort
[C113]
(S-Curve Abort)
This parameter, S-CURVE ABORT (C1),
addresses how the S-Curve Speed
Reference Generator handles a reduction
in the speed command before the S-
Curve Generator has reached its target
speed. For more information, see S-Curve
Abort on page 95.

DB
Protection
[C114]
(Dynamic Braking Resistor Protection
Selection)
The dynamic braking IGBT is limited as to
when it can be turned “on” (i.e. send
power to the dynamic braking resistors).
The dynamic braking IGBT is allowed to
be “on” while the drive is running (i.e.
while the speed regulator is released) and
for a period of ten (10) seconds after the
drive is stopped. If the dynamic braking
IGBT is still “on” ten seconds after the
drive stops running, the drive will turn “off”
the dynamic braking IGBT (thus stop
sending power to the dynamic braking
resistors) and d
eclare a “DB VOLTAGE”
fault or alarm (whether fault or alarm,
depends on setting of this parameter).

Release
[C115]
(Speed Reference Release)
The user can select when the Speed
Reference Release signal is asserted:
If the user does not want the drive to
wait for the mechanical brake to be
picked then SPD REF RELEASE can
be made equal to REG RELEASE
If the user does want the drive to wait
for the brake to be picked then SPD
REF RELEASE is not asserted until
BRAKE PICKED becomes true.
