SP600 AC Drive User Manual
Enables/disables a feature to issue a start or run command and 
automatically resume running at commanded speed after drive 
input power is restored.
0 = Disabled: The drive starts on the open-to-closed transition of 
the control source start input while no start inhibit conditions are 
present. (Edge-sensitive detection.)
1 = Enabled: The drive starts while the control source start input is 
closed and no start inhibit conditions are present. (Level-sensitive 
detection.) In this case, if the drive is powered up and the input is 
closed, the drive will automatically start.
Note that this feature (LevelSense Start) requires a digital input 
configured for run or start and a valid start contact.

ATTENTION: Be aware of the following:
• Setting parameter 168 to 1 (Enabled) immediately
applies output power to the motor when all start 
conditions are met. 
• If the drive is running from the terminal block,
LevelSense Start is enabled, and a fault occurs, the 
drive coasts to rest and generates a fault. In this 
case, resetting and clearing the fault immediately 
restarts the drive without any change to the start or 
stop input states.
When this function is enabled, the user must ensure 
that automatic start up of the driven equipment will not 
cause injury to operating personnel or damage to the 
driven equipment. In addition, the user is responsible 
for providing suitable audible or visual alarms or other 
devices to indicate that this function is enabled and 
the drive may start at any moment. Failure to observe 
this precaution could result in severe bodily injury or 
loss of life.
