These parameters are reserved for future use.
7M – Low Current Flag
The MVE has low and high current flags to give early warning of abnormal operation. The current flags can be configured to
indicate an abnormal current level during operation, between the normal operating level and the undercurrent or instantaneous
overcurrent trip levels. The flags can signal the situation to external equipment via one of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed flag value.
Range:
1% - 100% FLC
Default:
50%
Description:
Sets the level at which the low current flag operates, as a percentage of motor full load current.
7N – High Current Flag
Range:
50% - 600% FLC
Default:
100%
Description:
Sets the level at which the high current flag operates, as a percentage of motor full load current.
7O – Motor Temperature Flag
The MVE has a motor temperature flag to give early warning of abnormal operation. The flag can indicate that the motor is
operating above its normal operating temperature but lower than the overload limit. The flag can signal the
situation to external equipment via one of the programmable outputs.
Range:
0% - 160%
Default:
80%
Description:
Sets the level at which the motor temperature flag operates, as a percentage of the motor's thermal capacity.
7P, 7Q, 7R, 7S – Analog Output A
The MVE has an analog output, which can be connected to associated equipment to monitor motor performance.
Parameter 7P
Analog Output A
Options:
Current (% FLC) (default)
Current as a percentage of motor full load current.
Motor Temp (%)
Motor temperature as a percentage of the motor rated current
(calculated by the soft starter's thermal model).
Motor kW (%)
Motor kilowatts. 100% is motor FLC (parameter 1A) multiplied by mains
voltage. Power factor is assumed to be 1.0.
