ASTAT XL User Manual
Probable Cause
If the start current is too low, the motor will not produce enough
•
torque to accelerate to full speed. The soft starter may trip on
excess start time.
NOTE
Make sure the motor starting parameters are
appropriate for the application and that you are using
the intended motor starting profile. If parameter 6D is
set to Motor Set Select, check that the corresponding
input is in the expected state.
The load may be jammed. Check the load for severe overloading or
a locked rotor situation.
The SCRs in the ASTAT XL require at least 5 A of current to latch.
•
If you are testing the soft starter on a motor with full load
current less than 5 A, the SCRs may not latch correctly.
If the soft starter is connected to the motor using inside delta
•
configuration, the soft starter may not be correctly detecting
the connection. Contact your local supplier for advice.
• The soft stop settings may not be appropriate for the motor and
load. Review the settings of parameters 2H, 2I, 3H and 3I.
If the motor is very lightly loaded, soft stop will have limited
•
effect.
• These features are only available with in-line installation. If the
ASTAT XL is installed inside delta, these features will not operate.
The first Adaptive Control start is actually 'Constant Current' so
•
that the starter can learn from the motor characteristics.
Subsequent starts use Adaptive Control.
• The starter will trip on Lx-Tx Shorted on the first start attempt
after control power is applied. PowerThrough will not operate
if control power is cycled between starts.
Make sure you are saving the new value by pressing the ENTER
•
button after adjusting a parameter setting. If you press EXIT,
the change will not be saved.
• Check that the adjustment lock (parameter 15B) is set to Read &
Write. If the adjustment lock is set to Read Only, settings can
be viewed but not changed. You need to know the security
access code to change the adjustment lock setting.
The EEPROM may be faulty on the keypad. A faulty EEPROM
•
will also trip the soft starter, and the keypad will display the
message Parameter out of range. Contact your local supplier
for advice.
The keypad is not receiving data from the control PCB. Check the
cable connection.
