4.6 Basic Drive Setup Adjustments
Note: If b2-01 is set to a smaller value than E1-09 (Minimum Frequency), then DC Injection Braking will begin when the frequency falls to the
E1-09 value. The drive will not perform short-circuit braking when b2-01 = E1-09 = 0 Hz.
CLV and CLV/PM (A1-02 = 3, 7)
For these control modes, parameter b2-01 sets the starting frequency for Zero Speed Control (not position lock) at Stop. When
the output frequency falls below the setting of b2-01, Zero Speed Control is enabled for the time set in parameter b2-04.
Note: If b2-01 is set to lower than E1-09 (Minimum Frequency), then Zero Speed Control begins at the frequency set to E1-09.
n b3-01: Speed Search Selection at Start
Determines if Speed Search is automatically performed when a Run command is issued.
No.
b3-01
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.
