1 2 b Application
Three inputs (Start-Stop-FWD/REV). Set A1-03 to 3330 to initialize the drive and preset terminals S1, S2, and S5 to these
functions.
Refer to Setting 0: 3-Wire Sequence on page
Settin 2 Serial Communication (APOGEE FLN BACnet MEMOBUS/Modbus Metasys N2)
This setting requires entering the Run command via serial communications by connecting the RS-422/RS-485 serial
communication cable to control terminals R+, R-, S+, and S- on the terminal block.
Configuration on page 340
Settin Option Card
This setting requires entering the Run command via the communication option board by plugging a communication option
board into the CN5 port on the control PCB. Refer to the option card manual for instructions on integrating the drive into the
communication system.
If b1-02 is set to 3, but an option card is not installed in CN5, an oPE05 operation error will be displayed on the HOA keypad and the drive

will not run.

Selects how the drive stops the motor when the Run command is removed or when a Stop command is entered.

Settin amp to Stop
When the Run command is removed, the drive will decelerate the motor to stop. The deceleration rate is determined by the
active deceleration time. The default deceleration time is set to parameter C1-02.
When the output frequency falls below the level set in parameter b2-01, the drive will start DC injection or Zero Speed Control
depending on the selected control mode.
Settin 1 Coast to Stop
When the Run command is removed, the drive will shut off its output and the motor will coast (uncontrolled deceleration) to
stop. The stopping time is determined by the inertia and the friction in the driven system.
After a stop is initiated, any subsequent Run command entered will be ignored until the minimum baseblock time (L2-03) has expired. Do
Note:
not enter Run command until it has come to a complete stop. Use DC Injection at Start

Settin 2 DC In ection Bra in to Stop
When the Run command is removed, the drive will enter baseblock (turn off its output) for the minimum baseblock time
(L2-03). When the minimum baseblock time has expired, the drive will inject the amount DC current set in parameter b2-02
into the motor windings to brake the motor. The stopping time in DC Injection Braking to Stop is significantly faster compared
to Coast to Stop.
This function is not available in OLV/PM control mode (A1-02 = 5).
