07-09 =3: Coast to stop with timer
When a stop command is issued the motor will coast to a stop after the minimum Baseblock time (07-18) has expired
and the AC Drive ignores the run command until the timer has expired.
The total time of the timer is determined by the deceleration time (00-15, 17, 22 or 24) and the output frequency upon
stop. Refer to figure below for details.

07-10 = 0
: Speed search is disabled and the AC Drive output frequency starts from min. frequency (01-08).
07-10 = 1
: Speed search is enabled and activated only once after power-up and first run command.
07-10 = 2
: Speed search is enabled and activated after every run command
Note:
Speed search function is unavailable for AC Drive size 1 and 2 and control mode set to PMSLV (00-00=5).

Parameter 07-13 low voltage detection level can be adjusted from 150 to 300 Vdc (240V class) or 250 to 600 Vdc
(480V class).
When the AC input voltage is lower than the value set in 07-13 divided by 1.414 (AC voltage detection level) for the
time specified in 07-25, a low-voltage error "UV" will be displayed. If 07-25 = 0.00 sec., the UV error will be displayed
immediately.
Important Notes:
1. The AC Drive input voltage can limit the output voltage. The connected motor may stall if the input voltage drops
excessively or if the load is too big.
2. If the input voltage drops below the value set in 07-13, then the AC Drive output is turned off momentarily. The AC
Drive will not automatically start when power is restored.
