Quick Start Enable
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

Description
52 RDY 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.
Valid for inputs:
C001, C002, C003, C004,
C005
Required settings: B151=00
Notes:
•
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.
