Nidec Digistart D4 User Manual

Programmable Parameters
9.5 1 Motor Details
1A – Command Source
Options:
Digital Input (default)
The soft starter will accept start and stop commands
from the digital inputs.
Network
The soft starter will accept start and stop commands
from the communication expansion card.
Remote Keypad
The soft starter will accept start and stop commands
from the Remote Keypad.
Smart Card
The soft starter will accept start and stop commands
from the smart card.
Description: Selects the command source for controlling the soft starter.
1B – Motor Full Load Current
Range: Model dependent
Description: Matches the starter to the connected motor's full load current. Set to the full
load current (FLC) rating shown on the motor nameplate.
1C – Locked Rotor Time
Range: 0:01 - 2:00 (minutes:seconds) Default: 10 seconds
Description: Sets the maximum length of time the motor can sustain locked rotor current
from cold before reaching its maximum temperature. Set according to the
motor datasheet.
1D – Locked Rotor Current
Range: 400% - 1200% FLC Default: 600%
Description: Sets the locked rotor current of the connected motor, as a percentage of full
load current. Set according to the motor datasheet.
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.
1F – Reserved
Description: This parameter is reserved for future use.
9.6 2 Motor Start/Stop
2A – Start Mode
Options: Constant Current (default)
Adaptive Control
Description: Selects the soft start mode.
NOTE
The soft starter will apply the current limit on all soft starts, including adaptive
control. If the current limit is too low or the start ramp time (parameter 2B) is too
short, the motor may not start successfully.
