PROGRAMMING MENU
8L – Graph Minimum
Range:
0% – 600%
Default:
0%
Description:
Adjusts the lower limit of the performance graph.
8M – Current Calibration
Range:
85% - 115%
Default:
100%
Description:
Calibrates the soft starter's current monitoring circuits to match an external current metering device.
Use the following formula to determine the necessary adjustment:
Calibration (%) =
Current shown on EMX3 display
Current measured by external device
eg 102% =
66A
65A
NOTE
This adjustment affects all current-based functions and protections.
8N – Mains Reference Voltage
Range:
100 – 690 V
Default:
400 V
Description:
Sets the nominal mains voltage for the keypad's monitoring functions. This is used to calculate motor kilowatts
and kilovolt amperes (kVA) but does not affect the EMX3's motor control or protection.
8O Reserved
Description:
This parameter is reserved for future use.
9 Motor Data-2
The EMX3 can support two different starting and stopping motor data sets.
•
To use the EMX3 with two separate motors (such as a duty-standby configuration), use parameter 9A to select dual
thermal modelling and configure parameters 9B~9E to suit the second motor.
•
To use the EMX3 with two different motor data sets for the same motor (for dual speed motors or applications where
starting conditions may vary), use parameter 9A to select a single thermal model, and configure the starting and
stopping profiles as required in parameters 10A~10G. The soft starter will ignore parameters 9B~9E and will use
settings from the primary motor.
To select the secondary motor data set, a programmable input must be configured to parameter set selection (parameters 6A and 6F)
and the input must be active when the soft starter receives a start signal.
NOTE
You can only choose which motor data set to use while the soft starter is stopped.
9A – Dual Thermal Model
Options:
Single (default)
Dual
Description:
Activates dual thermal modelling. The dual thermal model is required only if the EMX3 is controlling two
physically separate motors.
9B – Motor FLC-2
Range:
Model dependent
Description:
Sets the secondary motor's full load current.
9C – Locked Rotor Time-2
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.
