Setting 0: Count Successful Restarts
The drive will continuously attempt to restart. If it restarts successfully, the restart counter is increased. This operation is
repeated each time a fault occurs until the counter reaches the value set to L5-01.
Setting 1: Count Restart Attempts
The drive will attempt to restart using the time interval set to parameter L5-04. A record is kept of the number of attempts to
restart to the drive, regardless of whether those attempts were successful. When the number of attempted restarts exceeds the
value set to L5-01, the drive stops attempting to restart.

L6: Torque Detection

The drive provides two independent torque detection functions that trigger an alarm or fault signal when the load is too heavy
(oL), or suddenly drops (UL). These functions are set up using the L6-oo parameters. Program the digital outputs as shown
below to indicate the underload or overload condition to an external device:
Note: When overtorque occurs in the application, the drive may stop due to overcurrent (oC) or overload (oL1). To prevent the drive from stopping,
use torque detection to indicate an overload situation to the controller before oC or oL1 occur. Use undertorque detection to discover
application problems like a torn belt, a pump shutting off, or other similar trouble.
