2) Low-current/ torque detection
<Example>
Select object of detection with f590: f590=1 (Current detection), 2(Torque detection)
f591=0 (Alarm only)
f592=1 (Low-current/ torque detection)
Output terminal function: 182 (SUPA) Shock monitoring pre-alarm signal
Alarm signal output
Output current/ torque (%)
f593-f596
f593
When setting f591=1 (Tripping), inverter trips after low-current/ torque is detected for the period of time
set with f595. Then, alarm signal remains ON.
3) In case of setting f597 and f598
Waiting time until shock monitoring detection after start-up (after operation command is on) can be set
by f597 (Shock monitoring detection start waiting time).
If eliminating the time during acceleration/ deceleration from detecting conditions, select f598
(Shock monitoring detection action selection) =1.
<Example>
f598=1, f597=5 (s), and acceleration exceeds 5 seconds.

* In case of less than f595, and the inverter is in acceleration/ deceleration status or over-current stall
during detection activates, detection time will be reset.
