Description
0/1000
[0]
NA
Displays the estimated time before an overload trip will occur if the present
operating conditions persist. If operating below ultimate trip current the value will
display the max value.
R
Secs
0/1000
[0]
NA
Displays the estimated time until the motor overload fault can be reset. The MTU
reset level is set by the OL reset parameter (80).
R
Time to PM
Hrs
0/1000
[0]
NA
Displays the estimated time to a preventive maintenance event if enabled. The
scheduled time for a PM event is set by the user via the PM Hours parameter
(126).This value can be reset by the user after an event via the meter reset parameter
(16).
R
22
Starts to PM
—
0/50000
[0]
NA
Displays the estimated number of starts to a PM event if enabled. The scheduled
number of starts for a PM event is set by the user via the PM Starts parameter
(127).This value can be reset by the user after an event via the meter reset parameter
(16).
R
23
Total Starts
—
0/30000
[0]
NA
Displays the total number of SMC starts. The SMC keeps a Start Counter which will
be incremented each time the SMC is started. This parameter cannot be reset by the
customer and leaves the factory with a value of 0.

NA
Displays the estimated motor speed during starting and stopping. This parameter is
only valid when using the linear speed starting or linear speed stopping modes.
