ADJUSTMENTS FOR REDUCED VOLTAGE SOFT-STOP (Ramp Down)
This, procedure to be used with all SERIES 25 control styles.
There are two ways the control can be used to achieve a soft-stop.
Normally, when a maintained closure is made between terminals Decel and Common,
the control voltage to the motor will begin to ramp down from running voltage to the initial
voltage value and will take the same amount of time to ramp down as it did to ramp up,
(Start Time and Stop Time are the same and use the same adjustment; Initial Torque and
Final Torque are the same and use the same adjustment).
An alternate method to performing a soft-start and soft-stop is to start the motor using the
Rampt adjustments and stop the motor using a combination of the Ramp2 adjustments
and Decel.
With either method it may be necessary to automatically turn off the motor power.
The illustrations below indicates how each method works.
