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.

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.
Refer to b2: DC Injection Braking on page 109
for details.

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 ignoreduntil 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 (
Refer to b2-03: DC Injection Braking Time at Start on page 109
) or Speed Search (
Refer to b3: Speed
Search on page 110
).
Setting 2: DC Injection Braking to Stop
When the Run command is removed, the drive will baseblock (turn off its output) for the minimum baseblock time (L2-03).
Once the minimum baseblock time has expired, the drive will brake the motor by injecting DC current into the motor
windings. The stopping time will be reduced as compared to coast to stop. The level of DC Injection current is set by
parameter b2-02 (default = 50%).
Note:
This function is not available when using PM Open Loop Vector.
