Selects a condition to activate Speed Search Selection at Start
SpdSrch Start AI (b3-01) or External Speed Search Command 1 or 2 from the
0: Start from 0 multi-function input.
1: start SPD 0: Triggered when a Run command is issued (normal).
1: Triggered when an external baseblock is released.
Set the current level to use to limit the output current during a

Activates and deactivates Speed Search at start in accordance
with whether a Run command was issued during an
SpdSrch Start UV undervoltage (Uv) condition. Function is active when a
0: Disabled momentary power loss (L2-01 = 1 or 2), Speed Search at start
1: Enabled (b3-01 = 1), and coasting to a stop (b1-03 = 1) are enabled.
0: Disabled
1: Enabled
Bkspin Srch Time1
Adjusts the direction of Speed Search to allow for backspin.
Bkspin Srch Time2
Sets the search frequency deceleration rate when searching from
BkspinSrchDecel1 the direction command when the momentary power loss time is
shorter than the time set in b3-50.
Sets the search frequency deceleration rate for a Speed Search
from the opposite direction of the direction command when the
BkspinSrchDecel2
momentary power loss time is equal to or longer than the time
set in b3-51.

PID Mode 0: Disabled
0: Disabled 1: Enabled (PID output becomes output frequency reference)
1: Enabled D=Fdbk 3: Enabled (PID output added to frequency reference)
3: Fref+PID D=Fdbk
Sets the proportional gain of the PID controller.
PID Gain
Sets the integral time for the PID controller.
Sets the maximum output possible from the integrator as a
percentage of the maximum output frequency.
