This parameter provides a torque pulse for the
programmed time period at the beginning of the
starting maneuver for ramp profile #2.

(Only available with Pump Control option) Allows
the ability to manually adjust the pump algorithm
slightly for different applications. The purpose of
this parameter is to allow the pump stop algorithm
to be more aggressive earlier in the ramp. If
experiencing overload trips during stopping, either
reduce the stopping time or try increasing this by
units of 5. Try not to exceed a value of 40.

Braking Current

When the Smart Motor Braking option is installed,
this parameter allows the user the ability to adjust
the braking current level applied to the motor.
Smart Motor Braking and Accu-Stop has the
capability to apply braking current to the motor
from the “at speed” condition. With Smart Motor
Braking, the braking maneuver continues until the
motor comes to rest, at which point the controller
automatically ceases braking action. Note that high
braking currents can introduce excessive vibration
to the motor couplings and/or gearing and
additional heating in the motor.

Braking Time
(SMB)
36 Sec
0…999
0
This parameter provides the ability to over-ride the
SMB function (zero-speed detection) and set an
exact time in which the braking current is applied to
the motor. This can be used for applications where
detecting zero speed is difficult or when the
purpose is to reduce the number of overload trips
associated with driving the motor to a complete
stop. Setting this to a specific value will turn off the
braking at a set time, each time a stopping
maneuver is performed. An ideal setting can be
accomplished through trial and error and should
always allow for some small coast time. Setting this
value to long will cause braking current to be
applied to a stopped motor and likely result in
overload trips.

1 – Hi Inertia
2 – Hi Friction
3 – Ramp 89
0 - Standard
Allows the user the ability to modify the braking
profile to match a particular load type. This
parameter is designed to only be used with the SMB
algorithm and not with timed brake. For the
majority of applications the standard profile will
work sufficiently. Adjusting this parameter should
really only be used when some type of problem
during braking is being encountered.
