Sequencing Logic - Parker AC890 Product Manual

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
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
Setting this parameter to TRUE causes the Drive to run in the forward direction.
RUN REVERSE
Setting this parameter to TRUE causes the Drive to run in the reverse direction.
NOT STOP
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
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.
