5.2 b: Application
• 2-Wire sequence 1:
Two inputs (FWD/Stop-REV/Stop). Initializing the drive by setting A1-01 = 2220, presets the terminals S1 and S2 to these
functions. This is the default setting of the drive.
Sequence on page 191.
• 2-Wire sequence 2:
Two inputs (Start/Stop-FWD/REV).
191.
• 3-Wire sequence:
Inputs S1, S2, S5 (Start-Stop-FWD/REV). Initialize the drive by setting A1-01 = 3330 presets the terminals S1, S2 and S5
to these functions. Refer to Setting 0: 3-Wire Sequence on page
Setting 2: MEMOBUS/Modbus Communications
To issue a Run command via serial communications, set b1-02 to "2" and connect the RS-485/422 serial communication cable
to R+, R-, S+, and S- on the removable terminal block.
Setting 3: Option Card
To issue the Run command via the communication option board, set b1-02 to "3" and plug a communication option board into
the 2CN port on the control PCB. Refer to the manual supplied with the option board for instructions on integrating the drive
into the communication system.
Note: If b1-01 is set to 3, but an option board is not installed in 2CN, an oPE05 operator programming error will be displayed on the digital
operator and the drive will not run.
n b1-03: Stopping Method Selection
Select how the drive stops the motor when a Stop command is entered or when the Run command is removed.
No.
b1-03
Setting 0: Ramp to Stop
When a Stop command is issued or 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.
DC Injection braking (for IM control) or Short Circuit Braking (PM Open Loop Vector) can be applied at the end of the ramp
in order to completely stop high inertia loads.
Setting 1: Coast to Stop
When a Stop command is issued or the Run command is removed, the drive will shut off its output and the motor will coast
(uncontrolled deceleration) to stop where the stopping time is determined by the inertia and the friction in the driven system.
