AC890PX AC Drive
SEQUENCING LOGIC
SETUP::SEQ & REF::SEQUENCING LOGIC
This function block contains all the parameters relating to the sequencing (start and stop) of the Drive.
Before the Drive will respond to the RUN FORWARD, RUN REVERSE or JOG parameters (cause the Drive to run or jog), the parameters DRIVE
ENABLE, NOT FAST STOP and NOT COAST STOP need to be set to TRUE. In addition, the Drive needs to be healthy (HEALTHY is TRUE).
The Drive will only respond to RUN FORWARD, RUN REVERSE and JOG if the Drive is in the Remote Sequencing mode.
If RUN FORWARD and RUN REVERSE are TRUE, both are ignored and the Drive will stop.
Parameter Descriptions
START DELAY PREF: 92.25 Default: 0.000 s Range: 0.000 to 30.000s
Delays the action of "ramping to setpoint" from the Run command. This can allow a period for motor flux to establish before the ramp to setpoint.
RUN FORWARD
PREF: 92.01 Default: FALSE Range: FALSE / TRUE
Setting this parameter to TRUE causes the Drive to run in the forward direction.
RUN REVERSE
PREF: 92.02 Default: FALSE Range: FALSE / TRUE
Setting this parameter to TRUE causes the Drive to run in the reverse direction.
NOT STOP PREF: 92.03 Default: FALSE Range: FALSE / TRUE
Setting this parameter TRUE will latch the RUN FORWARD or RUN REVERSE commands. Once latched, they can be reset to FALSE and the
Drive will continue to run. Setting NOT STOP to FALSE causes the run commands to be unlatched.
JOG
PREF: 92.04 Default: FALSE Range: FALSE / TRUE
Setting this parameter TRUE causes the Drive to run at the speed set by JOG SETPOINT (refer to the REFERENCE JOG function block). Once
jogging, setting JOG to FALSE causes the Drive to ramp to zero.
