Units Default Explanation
Edge-r : Following Power on or reset, the drive
will not start if Digital Input 1 remains closed.
The Input must be closed following a power on
or reset to start the drive.
Auto-0 : Following a Power On or Reset, the

- drive will automatically start if Digital Input 1 is
closed.
Auto 1 to 5 : Following a Fault, the drive will
make up to 5 attempts to restart at 20 second
intervals. The drive must be powered down to
reset the counter
When enabled, on start up the drive will
attempt to determine if the motor is already
rotating, and will begin to control the motor

observed when starting motors which are not
turning
Active when P1-12 = 1 or 2
0 : Following a stop and restart, the drive will
run at minimum speed
1 : Following a stop and restart, the drive will
run at the last setpoint speed
2 : As per setting 0, except that the Run
- 1 command will be determined by the status of
Digital Input 1, and the user is not required to
press the keypad start button
3 : As per setting 1, except that the Run
command will be determined by the status of
Digital Input 1, and the user is not required to
press the keypad start button
When P2-20 >0, the drive enters standby mode
