E76
DC Medium Voltage Detection Level
When the DC medium voltage decreases to the set voltage level or lower, U-EDC is output. The DC medium
voltage of the inverter is proportional to the input voltage. Therefore, when the DC medium voltage is
monitored, the power supply voltage error can be detected.
- E76 setting range 200 V line 200 V to 400 V, 400 V line 400 V to 800 V

Torque Detect 1 (Operation Level, Timer)
Torque Detect 2/Low Torque Detect (Operation Level, Timer)
This function sets the operation level and timer for the torque detect 1 TD1, torque detect 2 TD2, and low
torque detect U-TL.

Torque detect 1 TD1, Torque detect 2 TD2
The output signal TD1 or TD2 comes on when the torque value calculated by the inverter or torque
command value exceeds the level specified by the torque detect (operation level) set level, and when that
condition continues for the set period of torque detect (timer) or longer. The signal turns off when the
calculated torque drops to equal to or lower than 5% of the set level - motor rated torque. (The minimum
output signal range: 100 ms.)
