Parameter Descriptions
6-2 Maximum Resets
Range: Function:
1 [1–5] 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 decreases
by 1 after each successful start/stop cycle.
NOTICE
If the starter is manually reset, the reset counter returns
to 0.

8.6.1 Auto-Reset Delay

The soft starter can be configured to wait before auto-
resetting a trip. Separate delays can be set for trips in
groups A and B, or in group C.
6-3 Reset Delay Groups A & B
Range: Function:
5 s [00:05–15:00 (min:s)] Sets the delay before resetting group
*
A and group B trips.
6-4 Reset Delay Group C
Range:
5 minutes [5–60 (minutes)] Sets the delay before resetting
*

8.7 Secondary Motor Set

See parameters 1-1 to 1-16 for details.
7-1 Motor FLC-2
Range: Function:
[Motor dependent] Sets the secondary motor full load
current.
7-2 Locked Rotor Time-2
Range: Function:
10 s [0:01–2:00 Sets the maximum length of the time the
*
(min:s)] motor can run at locked rotor current from
cold before reaching its maximum
temperature. Set according to the motor
datasheet.
If this information is not available, set the
value to <20 s.
7-3 Start Mode-2
Option: Function:
Selects the soft start mode.
Constant current*
Adaptive control
7-4 Current Limit-2
Range: Function:
350% [100–600% Sets the current limit for constant current
*
FLC] and current ramp soft starting, as a
percentage of motor full load current.

7-5 Initial Current-2
Range: Function:
350% [100– Sets the initial start current level for current
*
600% ramp starting, as a percentage of motor full
FLC] load current. Set so that the motor begins to
accelerate immediately after a start is initiated.
If current ramp starting is not required, set the
initial current equal to the current limit.
7-6 Start Ramp Time-2
Range: Function:
10 s [1–180 s] Sets the total start time for an adaptive control
*
start or the ramp time for current ramp
starting (from the initial current to the current
limit).
7-7 Kick Start Level-2
Range: Function:
500% [100–700% FLC] Sets the level of the kick-start current.
*
7-8 Kick Start Time-2
Range: Function:
0000 ms [0–2000 ms] Sets the kick-start duration. A setting of
*
0 disables kick-start.
7-9 Excess Start Time-2
Range: Function:
Excess start time is the maximum time the soft
starter attempts to start the motor. If the
motor does not reach full speed 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.
20 s [0:00– Set as required.
*
4:00
(min:s)]
7-10 Stop Mode-2
Option: Function:
Selects the stop mode.
Coast to stop*
TVR soft stop
Adaptive control
Brake
7-11 Stop Time-2
Range:
0 s [0:00–4:00 (min:s)]
*
Function:
Sets the stop time.
