Description
Sequence
Selects the frequency reference input source.
0: Operator - Digital preset speed U1-01 or d1-01 to d1-17.
1: Terminals - Analog input terminal A1 (or terminal A2 based on
parameter H3-09).
2: Serial Com - Modbus RS-422/485 terminals R+, R-, S+, and S-.
3: Option PCB - Option board connected on 2CN.
4: Pulse Input (Terminal RP)
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-.
3: Option PCB - Option board connected on 2CN.
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).
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.
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)
Sets the scan rate of terminals S1 to S8.
0: 2ms - 2 scans (for quick response)
1: 5ms - 2 scans (for noisy environments)
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.
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
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.
Sets the DC injection braking current as a percentage of the Drive
rated current.
Sets the time of DC injection braking at start in units of 0.01
seconds.
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.
Sets the magnetic flux compensation as a percentage of the no-load
current value (E2-03).
