B2 DC Braking

B1-08 Run Command Acceptance During Programming RUN CMD at PRG
As a safety precaution the drive will not respond to a change in the run command when the digital
operator is being used to set or adjust parameters.This parameter will allow the drive to accept or
reject a change in the run command when the digital operator is being used to change or adjust param-
eters.

B2 DC Braking
B2-01 DC Braking Frequency (Zero Speed Level)
Setting Range:
Factory Default:
Sets the frequency at which DC injection braking (or initial excitation for flux vector control) starts, in
units of 0.1 Hz. When B2-01 < E1-09, DC injection braking starts from the minimum frequency refer-
ence (E1-09).
B2-02 DC Braking Current
Setting Range:
Factory Default:
DC injection braking current is set as a percentage of inverter rated current. In flux vector control
mode, initial excitation is performed according to the motor no-load current set in E2-03. This param-
eter should not be set unnecessarily high or motor overexcitation may occur.
