690+ Series Frequency Inverter

SEQUENCING LOGIC

This function block contains all the
parameters relating to the sequencing
(start and stop) of the Inverter.

Before the Inverter will respond to the
RUN FWD, RUN REV or JOG
parameters (cause the Inverter to run
or jog), the parameters DRIVE
ENABLE, NOT FAST STOP and
NOT COAST STOP need to be set to
TRUE. In addition, the Inverter needs
to be healthy (HEALTHY is TRUE).
The Inverter will only respond to
RUN FWD, RUN REV and JOG if
the Inverter is in the Remote
Sequencing mode.

If RUN FWD and RUN REV are
TRUE, both are ignored and the
Inverter will stop.

Parameter Descriptions

START DELAY

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 FWD

Range: FALSE / TRUE

Setting this parameter to TRUE causes the Inverter to run in the forward direction.

RUN REV

Range: FALSE / TRUE

Setting this parameter to TRUE causes the Inverter to run in the reverse direction.

NOT STOP

Range: FALSE / TRUE

Setting this parameter TRUE will latch the RUN FWD or RUN REV commands. Once latched,
they can be reset to FALSE and the Inverter will continue to run. Setting NOT STOP to FALSE
causes the run commands to be unlatched.

JOG

Range: FALSE / TRUE

Setting this parameter TRUE causes the Inverter to run at the speed set by JOG SETPOINT
(refer to the REFERENCE JOG function block). Once jogging, setting JOG to FALSE causes
the Inverter to ramp to zero.

CONTACTOR CLOSED

Range: FALSE / TRUE

Feedback used to indicate that the external contactor has been closed. It must be TRUE for the
sequencer to proceed from the SWITCHED ON state to the READY STATE, refer to
SEQUENCER STATE.

DRIVE ENABLE

Range: FALSE / TRUE

This provides a means of electronically inhibiting Inverter operation. Whilst running, setting this
parameter to FALSE disables the Inverter operation and causes the motor to coast.

NOT FAST STOP

Range: FALSE / TRUE

Whilst running or jogging, setting this parameter to FALSE causes the Inverter to ramp to zero.
The rate is set by FAST STOP RATE in the STOP function block. The action of setting NOT
FAST STOP to TRUE is latched. The Inverter cannot be restarted until fast stop is completed.
