605C 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, /FAST STOP and

/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.

A detailed description of the

sequencer states, as indicated by the

MAIN SEQ STATE parameter, is

described in Chapter 9. A

description of the sequence logic is

described in Chapter 4: “Operating

the Inverter” - Selecting Local or Remote Control.

Parameter Descriptions

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.

/STOP (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 /STOP to FALSE

causes the run commands to be un-latched.

JOG

Range: FALSE / TRUE

Setting this parameter TRUE causes the Inverter to run at the speed set by JOG SETPOINT

(refer to the JOG function block). Once jogging, setting JOG  to FALSE causes the Inverter to

ramp to zero.

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.

/FAST STOP (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 /FAST

STOP to TRUE is latched. The Inverter cannot be restarted until fast stop is completed.

/COAST STOP (NOT COAST STOP)

Range: FALSE / TRUE

Setting this parameter to FALSE disables the Inverter operation and causes the motor to coast.

The action of setting this parameter to TRUE is latched. The Inverter can not be restarted until

the coast stop is completed.
