b1-17: Run Command at Power Up
Determines whether an external Run command that is active during power up will start the drive.

Run Command at Power Up
0, 1
0
Setting 0: Run Command at Power Up Is Not Issued
Cycle the Run command to start the drive.
Note:
For safety reasons, the drive is initially programmed not to accept a Run command at power up (b1-17 = 0). If a Run command is issued at
power up, the AUTO LED will flash quickly.
Setting 1: Run Command at Power Up Is Issued
If an external Run command is active when the drive is powered up, the drive will begin operating the motor after the internal
start up process is complete.
WARNING! Sudden Movement Hazard. If b1-17 is set to 1 and an external Run command is active during power up, the motor will begin
rotating as soon as the power is switched on. Proper precautions must be taken to ensure that the area around the motor is safe prior to
powering up the drive. Failure to comply may cause serious injury.

b1-24: Commercial Power Operation Switching Selection
When the output frequency matches the power supply frequency (60 Hz), the PWM switching operation stops and switches
to operation with a direct commercial power supply connection.
Note:
1.
Switching can be enabled when an inductive motor is being driven in V/f or OLV control modes.
2.
Current value may change when a switch is made.
3.
Verify that the induction motor can be driven with the commercial power supply (e.g., the rated voltage and rated speed) prior to enabling
the commercial power switching selection.

Commercial Power Switching Selection
0, 1
0
Setting 0: Disabled
A voltage will be output with PWM switching operation regardless of the output frequency.
Setting 1: Enabled
When the deviation between the output frequency and the power supply frequency is less than or equal to the commercial
power switching output frequency coincidence level (b1-26), the PWM switching operation stops and switches to operation
with a direct commercial power supply connection.
Operation with a direct commercial power supply continues until the deviation between the output frequency and the power
supply frequency is greater than or equal to the commercial power switching output frequency coincidence/non-coincidence
level (b1-25 + b1-26).
n
b1-25/b1-26: Commercial Power Supply Operation Cancellation Level/Switching Level
These parameters set the value in 0.1 Hz increments at which commercial power supply switching selection is enabled and
disabled.
