12.4 DECELERATION TRIMPOT (DEC)
Sets the amount of time for the motor to
decelerate from full speed to zero speed. The
DEC Trimpot is factory set to 1.5 seconds.
For longer deceleration time, rotate the DEC
Trimpot clockwise. For more rapid deceleration,
rotate the DEC Trimpot counterclockwise. See
Figure 20.
Application Note: On applications with high inertial loads, the deceleration may
automatically increase in time. This will slow down the rate of speed of decrease to
prevent the bus voltage from rising to the Overvoltage Trip point. This function is
called Regeneration Protection. It is recommended that for very high inertial loads
that both the ACC and DEC Trimpots should be set to greater than 10 seconds.
12.5 SLIP COMPENSATION TRIMPOT (COMP)
Sets the amount of Volts/Hz to maintain set
motor speed under varying loads. Used to fine
tune the drive for improved load regulation. The
COMP Trimpot is factory set to 1.5 Volts/Hz,
which provides excellent speed regulation for
most motors.
To increase the slip compensation, rotate the
COMP Trimpot clockwise.* To decrease the slip
compensation, rotate the COMP Trimpot counterclockwise. See Figure 21.
*Note: Increasing the Slip Compensation beyond what is required may cause
unstable motor operation.
