Starting and Stopping Methods
Note Refer to Appendix D: “Programming” - REFERENCE, SEQUENCING LOGIC, REFERENCE STOP
and REFERENCE RAMP, for explanations of parameters.
Normal Stopping Methods
The Shipping Configuration is set to “Ramp to Stop” (at STOP TIME, set to 10.0s).
• To “stop” the locally controlled drive press the STOP key on the Keypad
• To “stop” the remotely controlled drive remove the 24V from the RUN input (terminal X15/02), and
from the STOP input (terminal X15/03)
Using the Keypad or DSE Configuration Tool, the drive can be selected to “Ramp to Stop”, or to “Coast to
Stop” at one of two rates (STOP TIME or FAST STOP TIME). To do this, change the RUN STOP MODE
parameter (PREF102.01) to the required selection.
Ramp to Stop
Set the SETUP::SEQ & REF::REFERENCE STOP::RUN STOP MODE parameter to RUN RAMP.
When a stop command is received, the drive decelerates from its actual speed towards zero for the
programmed DECEL TIME time. When this time has elapsed, SPEED TRIM is ramped to 0% in the
programmed STOP TIME time.
Note If SPEED TRIM does not operate, SPEED DEMAND is reduced to 0% in DECEL TIME.
The power stack remains energised until the STOP DELAY period has elapsed.
