Stopping Method Selection
Stopping Method
Selects the stopping method when the run command is removed.
0: Ramp to Stop
1: Coast to Stop
2: DC Injection to Stop

Selection
Zero-Speed Oper
Operation method when frequency reference is less than minimum
output frequency set in E1-09.
0: Operates according to frequency reference (E1-09 is disabled)
1: Output shuts off (coast to stop if less than E1-09)
2: Operates according to E1-09 (frequency reference set to E1-09)
3: Zero speed (frequency reference of zero is less than E1-09)

Local/Remote Run Selection
LOC/REM RUN Sel
0: Cycle External RUN - If the run command is closed when
switching from local mode to remote mode, the Drive will not
run.
1: Accept External RUN - If the run command is closed when
switching from local mode to remote mode, the Drive WILL
run.

DC Injection Braking
b2-01
DC Injection Braking Start
Frequency
DCInj Start Freq
Sets the frequency at which DC injection braking starts when ramp
to stop (b1-03 = 0) is selected. If b2-01< E1-09, DC Injection
braking starts at E1-09.

DC Injection Braking Current
DCInj Current
Sets the DC injection braking current as a percentage of the Drive
rated current.

DC Injection Braking Time at

DCInj Time @Start
Sets the time of DC injection braking at start in units of 0.01
seconds.

b2-04
DC Injection Braking Time at
Stop
DCInj Time @Stop
Sets the time length of DC injection braking at stop in units of 0.01
seconds.
1. When b1-03 = 2, actual DC Injection time is calculated as
follows: b2-04 * 10 * Output Frequency / E1-04.
2. When b1-03 = 0, this parameter determines the amount of time
DC Injection is applied to the motor at the end of the decel ramp.
3. This should be set to a minimum of 0.50 seconds when using
HSB. This will activate DC injection during the final portion of
HSB and help ensure that the motor stops completely.

Field Comp
Sets the magnetic flux compensation as a percentage of the no-load
current value (E2-03).
