Note:
Note these points when setting Stop in Position.
• The drive uses the deceleration time that was active when the drive received the Stop command or when the Run command was turned
OFF to calculate the stop time. If you change the deceleration time during deceleration, the positioning will not be accurate.
• Set b6-03 = 0.0 [Dwell Reference at Stop = 0.0], b6-04 = 0.0 [Dwell Time at Stop = 0.0 s].
• The KEB Ride-Thru function is not available. Set H1-xx ≠ 65, 66, 7A, 7B [MFDI Function Select = KEB Ride-Thru 1/2 Activate (N.O./
N.C.)].
• Set L3-04 = 0 [Stall Prevention during Decel = Disabled]. A dynamic braking option can be necessary for regenerative loads.
• Set L3-11 = 0 [Overvoltage Suppression Select = Disabled].
• The High Slip Braking function is not available. Set H1-xx ≠ 68 [MFDI Function Select ≠ High Slip Braking (HSB) Activate].
• Set C2-03, C2-04 = 0.00 [S-Curve Time @ Start of Decel, S-Curve Time @ End of Decel = 0.00 s].

b1-05 Operation Below
Minimum Freq
(0184)
0 : Operate at Frequency Reference
When the frequency reference is less than the value set in E1-09, the drive will continue to operate the motor as
specified by the frequency reference.
If the motor speed is less than or equal to the value set in b2-01 [DC Injection/Zero SpeedThreshold] when you
enter the Stop command (or deactivate the Run command), the drive will do Zero Speed Control for the time set
in b2-04 [DC Inject Braking Time at Stop] and then turn OFF its output.
1 : Baseblock (Motor Coasts)
If the frequency reference is less than the value set in E1-09, the drive stops motor voltage output and the motor
coasts to stop. If the motor speed is less than or equal to the value set in b2-01, then the drive will do Zero Speed
Control for the time set in b2-04.

V/f CL-V/f OLV CLV AOLV
Sets the reverse operation function. Disable reverse operation in fan or
pump applications where reverse rotation is dangerous.
V/f CL-V/f OLV CLV AOLV
Sets the drive operation when the frequency reference decreases to less than
the value set in E1-09 [Minimum Output Frequency].
