b2-01: DC Injection Braking Start Frequency
Active when “Ramp to Stop” is selected as the stopping method (b1-03 = 0).
No. Name Setting Range Default
b2-01 DC Injection Braking Start Frequency 0.0 to 10.0 Hz 0.5 Hz
V/f Control
Sets the starting frequency for DC Injection Braking at Stop. When the output frequency falls below the setting of b2-01, DC
Injection Braking is enabled for the time set in parameter b2-04.

b3-01: Speed Search Selection at Start
Determines if Speed Search is automatically performed when a Run command is issued.
No. Parameter Name Setting Range Default
b3-01 Speed Search Selection at Start 0, 1 0
Setting 0: Disabled
This setting starts operating the drive at the minimum output frequency when the Run command is entered. If external Speed
Search 1 or 2 is already enabled by a digital input, the drive will start operating with Speed Search.
Setting 1: Enabled
This setting performs Speed Search when the Run command is entered. The drive begins running the motor after Speed Search
is complete.

EZ Sleep/Wake-up Function
To enable EZ Sleep/Wake-up functionality on the drive, first set parameter b5-89 to 1. The default setting for b5-89 is 0, which
disables the EZ Sleep functionality and related parameters, except for parameter b5-91, EZ Sleep Minimum Speed.
Setting b5-89 to 1 disables the existing PID Sleep function (b5-15) and enables the EZ Sleep/Wake-up functionality.
EZ Sleep and Minimum Speed Units
Parameter b5-90, EZ Sleep Unit, determines the unit, range, and resolution of parameters b5-92 and b5-93. When set to Hz,
the range is 0.1 to 400.0 Hz. When set to RPM, the range is 0 to 24000 RPM. Changing b5-90 will NOT automatically re-
scale the values of b5-92 and b5-93.
