Using Intelligent Input Terminals

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

time.

Inverter output turns OFF normally in Stop 
Mode.

B151=00

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.

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.
