PROGRAMMABLE PARAMETERS
5B – Current Imbalance Delay
Range:
0:00 - 4:00 (minutes:seconds)
Default:
3 seconds
Description:
Slows the EMX4e's response to current imbalance, avoiding
trips due to momentary fluctuations.
5C – Undercurrent
Range:
0% - 100%
Default:
20%
Description:
Sets the trip point for undercurrent protection, as a percentage
of motor full load current. Set to a level between the motor's
normal working range and the motor's magnetising (no load)
current (typically 25% to 35% of full load current). A setting of
0% disables undercurrent protection.
5D – Undercurrent Delay
Range:
0:00 - 4:00 (minutes:seconds)
Default:
5 seconds
Description:
Slows the EMX4e's response to undercurrent, avoiding trips due
to momentary fluctuations.
5E – Overcurrent
Range:
80% - 600%
Default:
400%
Description:
Sets the trip point for overcurrent protection, as a percentage of
motor full load current.
5F – Overcurrent Delay
Range:
0:00 - 1:00 (minutes:seconds)
Default:
0 second
Description:
Slows the EMX4e's response to overcurrent, avoiding trips due
to momentary overcurrent events.
5G – Excess Start Time
Range:
0:00 - 4:00 (minutes:seconds)
Default:
20 seconds
Description:
Excess start time is the maximum time the EMX4e will attempt
to start the motor. If the motor does not transition to Run mode
within the programmed limit, the starter will trip. Set for a
period slightly longer than required for a normal healthy start. A
setting of 0 disables excess start time protection.
5H – Restart Delay
Range:
00:01 - 60:00 (minutes:seconds)
Default:
10 seconds
Description:
The EMX4e can be configured to force a delay between the end
of a stop and the beginning of the next start. During the restart
delay period, the display shows the time remaining before
another start can be attempted.
