Rockwell Automation SP120 AC Drive Demo Unit - Manual (Page 20)

Running the Demo Unit 4-8
Step 11. Set P-13 [ CONFIGURABLE OUTPUT LEVEL ] to 30.0.
This sets the level at which the output will turn on to
30.0 Hz.
Step 12. Turn the speed pot ( ANALOG CHAN #1) fully
clockwise. The red indicator lamp should be on.
Step 13. Press to enter display mode.
Step 14. Press until d-01 [ OUTPUT FREQUENCY ] is
displayed.

Step 16. Set the s TOP / RUN switch to STOP .
Lab 4: Programming various stopping methods.
Tools required: None
This lab consists of three parts:
a. Programming the drive for a coast-to-rest stop.
b. Programming the drive for a ramp-to-rest stop.
c. Programming the drive for DC injection braking.

Note: The drive may be at the default value of 0
(Ramp-to-Rest), which means the output voltage
and frequency is lowered based on the decel time.
During the previous labs, you may have noticed
how quickly the drive stopped.
Step 4. Set P-34 to 1 (Coast-to-Rest).
