BI: Speed controller enable / n_ctrl enable

VECTOR_G Can be changed: T
Data type: Unsigned32 / Binary
P-Group: Commands
Not for motor type: -
Min
-
Description: Sets the signal source for the command "enable speed controller" (r0898.12).
0 signal: Set the I component and speed controller output to zero.
1 signal: Enable speed controller.
Dependency: Refer to: r0898
Note: If "enable speed controller" is withdrawn, then an existing brake will be closed.
If "speed controller enable" is withdrawn, the pulses are not suppressed.

Power unit monitoring time / PU t_monit

B_INF, VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: Commands
Not for motor type: -
Min
100.0 [ms]
Description: Sets the monitoring time for the power unit.
The following applies for infeeds and drives:
The monitoring time is started after an 0/1 edge of the ON/OFF1 command. If the power unit does not return a
READY signal within the monitoring time, then fault F06000 (infeeds) or F07802 (drives) is output.
For drives, the following also applies:
After the pulse enable (operation enabled, p0852), the monitoring time is re-started. If the infeed does not signal
ready to the drive within the monitoring time (using BI: p0864 of the drive), fault F07840 is initiated.
Notice: The maximum time to pre-charge the DC link is monitored in the power unit and cannot be changed. The maximum
duration of the pre-charging depends on the power class and the power unit design.
The monitoring time for the pre-charging is started after the ON command (BI: p0840 = 0/1 signal). Fault F30027 is
output when the maximum pre-charging duration is exceeded.
Note: The factory setting for p0857 depends on the power class and the design of the power unit.
The monitoring time for the ready signal of the power unit includes the time to pre-charge the DC link and, if relevant,
the de-bounce time of the contactors.
If an excessively low value is entered into p0857, then after enable, this results in the corresponding fault.

BI: Unconditionally close holding brake / Uncond close brake

VECTOR_G Can be changed: T
Data type: Unsigned32 / Binary
P-Group: Commands
Not for motor type: -
Min
-
Description: Sets the signal source for the command "unconditionally close holding brake".
Dependency: Refer to: p0855
Note: The signal via BI: p0858 (unconditionally close holding brake) has a higher priority than via BI: p0855 (unconditionally
open holding brake).
For a 1 signal via BI: p0858, the command "unconditionally close the holding brake" is executed and internally a zero
setpoint is entered.
