(2) 07-24=0, disable direction-detection speed search：
Speed search is executed using speed search operating current defined in parameter 07-20. In
case speed search is not successful (e.g. motor speed is too low) a speed search time-out
warning is displayed. Set 07-19 to value greater than 0 to enable DC braking at speed search if
a time-out occurs frequently.

Start-Up Mode Selection of SLV Coast to Stop (07-26)
(1) In SLV mode (00-00=2) set the stop mode to the coast stop (07-09=1) or to the coast to stop
with timer (07-09=3). After a stop command is issued (coast to stop or coast to stop with times)
the speed search function is automatically actived for the next start.
(2) When 07-26=0，speed search function is enabled. (default setting)
(3) When 07-26=1，normal start

Start Selection after Fault During SLV Mode (07-27)
(1) When 07-27=0，speed search function is enabled. (default setting)
(2) When 07-27=1，normal start
Notes:
Set the parameter to 1 (normal start) after fault has occurred and mechanical brake is used to
stop the motor.

Start after External BaseBlock (07-28)
(1) When 07-28=0，speed search function is enabled. (default setting)
(2) When 07-28=1，normal start
Notes:
Set parameter to 1 for the control mode of V/F mode (00-00=0) or SLV mode (00-00=2) when the
external base blockactive time is longer than the time the motor needs to come to a complete stop.
After the external base block command is removed, the inverter will accelerate from minimum
frequency.

Start Frequency of Speed Search Selection (07-33)
07-33=0：The start speed search from the maximum output frequency of motor.
07-33=1：The inverter start speed search from setting frequency command.
