Name
Electronic thermal relay function prealarm
Description
Appears if the cumulative value of the Pr. 9 Electronic thermal O/L relay reaches or exceeds 85% of the
preset level. If it reaches 100% of the Pr. 9 Electronic thermal O/L relay setting, a motor overload trip (E.
THM) occurs.
The THP signal can be simultaneously output with the [TH] display. For the terminal used for the THP
signal output, assign the function by setting "8" (positive logic) or "108" (negative logic) in any of Pr. 190
to Pr. 196 (output terminal function selection). (Refer to Chapter 4 of the Instruction Manual (Applied))
Check point
y Check for large load or sudden acceleration.
y Is the Pr. 9 Electronic thermal O/L relay setting is appropriate? (Refer to page 57.)
Corrective action
y Reduce the load weight or the number of operation times.
y Set an appropriate value in Pr. 9 Electronic thermal O/L relay. (Refer to page 57.)

Name
Maintenance signal output
Description
Indicates that the cumulative energization time of the inverter has reached a given time.
When the setting of Pr. 504 Maintenance timer alarm output set time is the initial value (Pr. 504 = "9999"),
this protective function does not function.
Check point
The Pr. 503 Maintenance timer setting is larger than the Pr. 504 Maintenance timer alarm output set time
setting. (Refer to Chapter 4 of the Instruction Manual (Applied).)
Corrective action
Setting "0" in Pr. 503 Maintenance timer erases the signal.

Check point
y Check that the torque command is not larger than required.
y Check that the speed limit level is not low.
Corrective action
y Decrease the torque command.
y Increase the speed limit level.
