Run Command Selection
Run Source
Selects the run command input source.
0: Operator -
RUN and STOP keys on Digital Operator.
1: Terminals - Contact closure on terminals S1 or S2.
2: Serial Com - Modbus RS-422/485 terminals R+, R-, S+, and S-.

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
3: Coast with Timer (A new run command is ignored if received
before the timer expires).

Reverse Operation Selection
Reverse Oper
Determines the forward rotation of the motor, and if reverse
operation is disabled.
0: Reverse Enabled
1: Reverse Disabled
2: Exchange Phase - Change direction of forward motor rotation.

Minimum Output Frequency
(E1-09) or Less Operation
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)

Digital Input Scan Time
Cntl Input Scans
Sets the scan rate of terminals S1 to S8.
0: 2ms - 2 scans (for quick response)
1: 5ms - 2 scans (for noisy environments)

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.

RUN CMD at PRG
0: Disabled - Run command accepted only in the operation menu.
1: Enabled - Run command accepted in all menus
(except when b1-02 = 0).

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
Start
DCInj Time @Start
Sets the time of DC injection braking at start in units of 0.01
seconds. 0.00 to

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.

Magnetic Flux Compensation
Capacity
Field Comp
Sets the magnetic flux compensation as a percentage of the no-load
current value (E2-03).
0 to1000 0% - - A -
Denotes that parameter can be changed when the Drive is running.
