16 VS-616G5 Programming Manual

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. <1110>

Table 1:

B2 DC Braking

Setting Range: 0.0 to 10.0Hz

Factory Default: 0.5Hz

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).

Setting Range: 0 to 100%

Factory Default: 50%

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.
