2.13) Inv OH Warn (Inverter Overheat Warning)
Inverter Overheat is ON, when the heatsink inside the inverter is higher than the overheat alarm level. This signal is
only for an alarm, not for the inverter trip.

2.14) Trq Det.
Trq Det is ON when the torque output of ASR reaches the setting torque level.
Code Display Description Range Unit Default
DIO_53 TD level Torque Detect Level 0.0 ~ 250.0 % 0.0
DIO_54 TD Band TD hysterisis band 0.1 ~ 10.0 % 0.5
2.15) Trq Lmt Det
Trq Lmt Det is ON when the output of ASR (Torque reference) is saturated so that its limit value is
generated.
2.16) OverLoad
Overload is ON when the inverter output current is higher than the overload alarm level. (On the basis of the rated
current of the motor) Refer to the following values of overload alarm level (DIO_57) and overload alarm time
(DIO_58).
z DIO_57: [Overload warning level], DIO_58 [Overload warning time]
If the inverter output current keeps flowing more than overload alarm level (DIO_57) and longer than overload alarm
time (DIO_58), alarm signal is triggered. The overload signal is canceled when the inverter output current flows less
than overload alarm level (DIO_57) and longer than overload alarm time (DIO_58) has passed.
Overload alarm signal can be generated by the multi-function outputs (1A-1B, 2A-2B, OC1-EG). “OL” should be set in
the DIO_41, 42 and 43 [Multi-function auxiliary terminal output setting] to use this function. Even if overload occurs,
its alarm signal is generated through the multi-function output terminal and the inverter keeps running.
