Jam Warning
Parameter 21, Jam Warn Level, allows the installer to define the current at which
the EtherNet Module will indicate a warning. It is user-adjustable from
100…600% FLA.
The E1 Plus EtherNet/IP Module will indicate a Jam warning if:
• No warning currently exists
• Jam Warning is enabled
• Jam Inhibit Time has expired
• The motor current is equal to or greater than the Jam Warn Level
When the Jam Warning conditions are satisfied, the following will occur:
• Bit 2 in Parameter 4, Warning Status, will go to “1”
• Bit 1 in Parameter 10, Device Status, will go to “1”
Underload Protection Motor current less than a specific level may indicate a mechanical malfunction in
the installation, such as a torn conveyor belt, damaged fan blade, broken shaft, or
worn tool. Such conditions may not harm the motor, however, rapid detection
may help to minimize equipment damage and loss of production.
Underload Warning
The following parameters are available for configuring the E1 Plus EtherNet/IP
Module's underload warning performance:
• Parameter 22, UL Inhibit Time, allows the installer to inhibit an underload
indication from occurring during the motor starting sequence. It is
adjustable from 0…250 seconds.
• Parameter 23, UL Warn Level, allows the installer to define the current at
which the E1 Plus EtherNet/IP Module will indicate a warning. It is user-
adjustable from 30…100% of the FLA dial setting.
The E1 Plus EtherNet/IP Module will immediately indicate an Underload
warning if:
• No warning currently exists
• Underload Warning is enabled
• UL Inhibit Time has expired
• The motor current is less than the UL Warn Level
IMPORTANT The Jam Warning function does not include a time delay feature.
Once the Jam Inhibit Time has expired, the Jam Warning indication is
instantaneous.
