Using Intelligent Input Terminals

Quick Start Enable

Operations and Monitoring

When the [RDY] input is ON, the inverter is always in Run Mode, even when the motor rotation has stopped. The pupose of the quick start feature is to improve (decrease) the startup time of the motor in response to a Run Command.

CAUTION: While the [RDY] input is ON, voltage will be present on the output of the inverter, even when the motor is still. In this case:

• Do not touch the motor output terminals. Otherwise, there is the danger of electric shock.

•Do not short the motor leads together or to ground. Otherwise, you may damage the inverter output circuit

Quick Start Enable

ON

Inverter output is always ON (even when motor

 

 

 

 

rotation has stopped) to improve motor startup

 

 

 

 

time.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

OFF

Inverter output turns OFF normally in Stop

 

 

 

 

Mode.

•When the [RDY] input is ON, the inverter output is

energized the Run LED is always ON.

• When the [RDY] input is ON, you may edit only

 

 

 

parameters that can be edited in Run Mode. To edit

 

 

 

any parameter, turn OFF the [RDY] input and the

 

 

 

 

 

 

Run Command to put the inverter in Stop Mode.

See I/O specs on page 4–6.

•

Function B151 can also enable the Quick Start

 

 

 

function (B151=01). In that case, the [RDY] input

 

 

 

should not be used, because the inverter ignores it.
