Range
*10 s 00:01–60:00 (mi-

Table 114: 5-17 - Starts per Hour
Range Function
*0 0–10 Sets the maximum number of starts the soft starter attempts in a 60-minute period. A setting of 0 disables this pro-
tection.
Table 115: 5-18 - Phase Sequence
Option Function
Selects which phase sequences the soft starter allows at a start. During its pre-start checks, the soft starter
examines the sequence of the phases at its input terminals and trips if the actual sequence does not match
the selected option.
When using DC brake, the mains supply must be connected to the soft starter (input terminals L1, L2, L3)
in positive phase sequence. Parameter 5-18 Phase Sequence must be set to Positive Only.
* Any Sequence
Positive only
Negative Only

Table 116: 6-1 - Auto-Reset Count
Range Function
*0 0–5
Sets how many times the soft starter auto-resets if it continues to trip.
The reset counter increases by 1 each time the soft starter auto-resets, and resets after a successful start.
Setting this parameter to 0 disables auto-reset.

Function
Excess start time is the maximum time the soft starter attempts to start the motor.
If the motor does not transition to Run mode within the programmed limit, the soft starter trips.
Set for a period slightly longer than required for a normal healthy start. A setting of 0 disables excess
start time protection.
Function
The soft starter can be configured to force a delay between the end of a stop and the beginning of
the next start.
During the restart delay period, the display shows the time remaining before another start can be
attempted.
Function
Sets a delay before the soft starter auto-resets a trip.
