5.2 b: Application
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.
403.
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.
Note: After a stop is initiated, any subsequent Run command that is entered will be ignored until the Minimum Baseblock Time (L2-03) has
expired. Do not attempt to start the motor again until it has come to a complete stop. To start the motor before it has stopped completely,
use DC Injection at start
