Range Unit Description
Max. Start Time
30 SEC.
1-60 sec. Sets Maximum Start Time
The maximum allowable start time, from the start signal to the
end of the acceleration process. If voltage/speed does not reach
nominal during Max. Start Time then ASTAT-XT will trip the
motor and create a fault. The LCD will display the Long Start
Time
fault message.
For example, this can occur when the Current Limit setting
is too low.
Notes:
• When Overload Class is set to NEMA Class 10 Max.
Start Time
can be set to 15 seconds maximum.
• When Overload Class is set to IEC Class 10 or NEMA
Class 20
Max. Start Time can be set to 30 seconds
maximum.
• When Overload Class is set to IEC Class 20 or NEMA
Class 30 Max. Start Time
can be set to 60 seconds
maximum with limitation automatically calculated by the soft
starter.
Number of Starts
10
1-10, OFF Sets Number of Starts permitted during Duty Cycle Time (see
below).
Limits the Number of Starts during the period of time
defined by Duty Cycle Time.
If you try to start even one more time within that period the
START Lockout
period will take effect.
Duty Cycle Time
30 Min.
1–60 min. Sets Duty Cycle Time during which Number of Starts is counted.
During the START Lockout period the Wait before RST
XX Min
message will be displayed.
Start Lockout
15 Min.
1–60 min. Sets START Lockout time during which starting is disabled after
Too Many Starts
trip.
EOR Relay Delay
5 Sec.
0-120 sec. Sets the time delay for the End of Ramp relay to close.
End of Ramp relay can signal that the motor is at its full speed
which can be used for closing the bypass contactor and for
loading the motor.

Soft Start Parameters
The ASTAT-XT incorporates five starting curves to enable you to select a suitable torque curve.
Soft Start Curve 0
– Standard curve (Default). This curve is the most suitable curve for preventing prolonged
starting and motor overheating.
Note:
When ASTAT-XT is connected in DELTA Conf., the ASTAT-XT will always use Curve 0 regardless of the curve
defined.
