Bi-Directional Speed
Search Selection
This parameter enables the drive to detect
motor direction during speed search.
0: Disabled–Drive uses frequency reference
direction.
1: Enabled–Drive uses detected direction.

Speed Search Method
Selection
Sets the speed search method used at start-up
and after a momentary power loss.
0: Current Detection Type
1: Speed Estimation Type
Parameter b3-01 enables this function at start,
and parameter L2-01 enables this function
during momentary power loss.
Current Detection Type - Start speed search
from max frequency or from the frequency
when momentary power loss occurred. Detects
motor speed based on the current level
(conventional method).
Speed Estimation Type - Estimates the motor
speed when speed search begins. Accelerates or
decelerates to the estimated frequency. Works
in both forward and reverse.

Interval Time
Sets waiting time until the search retry
operation beginning when searching for the
speed of PM in 0.1 seconds.

b4: Timer Function
Use b4 parameters to configure timer function operation.
b4-01
Timer Function
On-Delay Time
Used in conjunction with a multi-function
digital input (H1- = 18) and a multi-
function digital output (H2- = 12)
programmed for the timer function. This sets
the amount of time between digital input
closure and digital output activation.
