386 AI1 SLEEP DELAY 6 (2.2.2.10)
This parameter defines the time the analogue input signal has to stay under the sleep limit
determined with parameter ID385 in order to stop the AC drive.
388 AI2 SIGNAL SELECTION * 234567 (2.2.9, 2.2.21, 2.2.3.1)
Connect the AI2 signal to the analogue input of your choice with this parameter. For more
information about the TTF programming method, see Chapter 8.9 "Terminal to function" (TTF)
393 AI2 REFERENCE SCALING, MINIMUM VALUE 6 (2.2.3.6)
394 AI2 REFERENCE SCALING, MAXIMUM VALUE 6 (2.2.3.7)
Additional reference scaling. If the values of both ID393 and ID394 are zero scaling is set off.
The minimum and maximum frequencies are used for scaling. See parameters ID303 and
ID304
395 AI2 JOYSTICK HYSTERESIS 6 (2.2.3.8)
This parameter defines the joystick dead zone between 0 and 20%. See ID384.
396 AI2 SLEEP LIMIT 6 (2.2.3.9)
The AC drive is stopped if the AI signal level falls below the Sleep limit defined with this
parameter. See also parameter ID397 and Fig. 60 Joystick hysteresis with minimum frequency
See ID385.
