L4-01 and L4-02 are used in conjunction with the multi-function outputs,
(H2-01and H2-02) as a setpoint and hysteresis for a contact closure.
Determines how the drive will react when the frequency reference is lost.
0: Stop (Disabled) - Drive will not run at the frequency reference.
1: Enabled @ % of PrevRef - Drive will run at a percentage (L4-06) of the
frequency reference level at the time frequency reference was lost.
Note: Only available in the Hand Mode (P5-01 = 0).
If Frequency Reference loss function is enabled (L4-05 = 1) and Frequency
Reference is lost, then the drive will run at reduced frequency reference
determined by L4-06. New Fref=Fref at time of loss x L4-06.
Note: Only available in the Hand Mode (P5-01 = 0)
Determines the number of times the drive will perform an automatic
restart.
Determines if the fault contact activates during an automatic restart
attempt.
0: No Flt Relay - fault contact will not activate during an automatic restart.
1: Flt Relay Active - fault contact will activate during an automatic restart.
If the restart fails (or is not attempted due to a continuing fault condition,
e.g. an OV fault) the drive waits the Maximum Restart Time After Fault
(L5-03) before attempting another restart. This parameter is not applicable
to Loss of Prime Fault.
