VersiStart p III
1E – Motor Service Factor
Range:
100% - 130%
Default:
105%
Description:
Sets the motor service factor used by the thermal model. If the motor
runs at full load current, it will reach 100%. Set according to the
motor datasheet.
NOTE
Parameters 1C, 1D and 1E determine the trip current for motor overload
protection. The default settings of parameters 1C, 1D and 1E provide
Motor Overload Protection: Class 10, Trip Current 105% of FLA (full load
amperage) or equivalent.
10.6 2 Motor Start/Stop
2A – Start Mode
Options:
Constant Current (default)
Adaptive Control
Description:
Selects the soft start mode.
NOTE
The VersiStart p III will apply the current limit on all soft starts, including
adaptive control. lf the current limit is too low or the start ramp time
(parameter 2B) is too short, the motor may not start successfully.
2B – Start Ramp Time
Range:
0:01 - 3:00 (minutes:seconds)
Default:
10 seconds
Description:
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).
2C – Initial Current
Range:
100% - 600% FLC
Default:
200%
Description:
Sets the initial start current level for current ramp starting, as a
percentage of motor full 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.
2D – Current Limit
Range:
100% - 600% FLC
Default:
350%
Description:
Sets the current limit for constant current and current ramp soft
starting, as a percentage of motor full load current.
2E – Adaptive Start Profile
Options:
Early Acceleration
Constant Acceleration (default)
Late Acceleration
Description:
Selects which profile the VersiStart p III will use for an Adaptive
Control soft start.
