PROGRAMMABLE PARAMETERS
9.5
1 Motor Details
1A –
Command Source
Options:
Digital Input
(default)
The EMX4e will accept start and stop
commands from the digital inputs.
Network
The EMX4e will accept start and stop
commands from the communication
expansion card.
Remote Keypad
The EMX4e will accept start and stop
commands from the Remote Keypad.
Smart Card
The EMX4e 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.
