230 Actual signals and parameters
DC BRAKING DC current braking function active.
If parameter 2102 STOP FUNCTION is set to COAST, DC
braking is applied after the start command is removed.
If parameter 2102 STOP FUNCTION is set to RAMP, DC
braking is applied after the ramp.

2105 DC HOLD
SPEED
Defines the DC hold speed. See parameter 2104 DC HOLD
CTL.
5rpm
0…360 rpm Speed 1 = 1 rpm
2106 DC CURR REF Defines the DC hold current. See parameter 2104 DC
HOLD CTL.
30%
0…100% Value as a percentage of the nominal motor current
(parameter 9906 MOTOR NOM CURR)
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 1601 RUN ENABLE.
• 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
1001 EXT1 COMMANDS is set to DI1P,2P; DI1P,2P,3 or
DI1P,2P,3P) is powered up and the corresponding digital
inputs (DI1 and DI2 or DI3) are at high level during power-
up.
