230 Actual signals and parameters
DC BRAKING
DC current braking function active.
If parameter
, DC
braking is applied after the start command is removed.
If parameter
, DC
braking is applied after the ramp.

2105 DC HOLD
SPEED
Defines the DC hold speed. See parameter
.
5 rpm
0…360 rpm
Speed
1 = 1 rpm
2106 DC CURR REF Defines the DC hold current. See parameter
30%
0…100%
Value as a percentage of the nominal motor current
(parameter
)
1 = 1%
2107 DC BRAKE
TIME
Defines the DC brake time.
0.0 s
0.0…250.0 s
Time
1 = 0.1 s
2108 START INHIBIT Sets the Start inhibit function on or off. If the drive is not
actively started and running, the Start inhibit function
ignores a pending start command in any of the following
situations and a new start command is required:
• a fault is reset.
• Run enable signal activates while the start command is
active. See parameter
• control mode changes from local to remote.
• external control mode switches from EXT1 to EXT2 or
from EXT2 to EXT1.
• the drive that is set to external pulse start (parameter
is set to
or
) is powered up and the corresponding digital
inputs (DI1 and DI2 or DI3) are at high level during power-
up.
