[Flying Start En]
Enables/Disables the ability of the drive to connect to a spinning motor at
actual rpm when a start command is issued.
• “Enabled” = When the drive is turned on, the speed of the motor is
measured and the ramp output is set accordingly. The drive then runs at the
set reference value.
• “Disabled” = When the drive is turned on, the ramp starts from zero.
Main uses:
• To connect to a motor that is already spinning due to its load (for example, in
the case of a pump, the flowing medium).
• Re–connection to a spinning motor after a fault or alarm.
Note: If the Flying Start function is disabled, ensure that the motor is not
spinning when the drive is turned on, or harsh motor deceleration in current
limit may occur.

[Logic Mask]
Determines which ports can control the drive when Par 1377 [Write Mask Act], bit 15 is set to “1.” If the bit for a port is set to “0,” the port will have no
control functions except for stop. 0 = Control Masked, 1 = Control Permitted, x = Reserved.
