2 Parameters
2.2 List of parameters
p0855[0...n] BI: Unconditionally release holding brake / Uncond open brake
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for the command "unconditionally open holding brake".
Dependency: Refer to: p0858
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: The signal via BI: p0858 (unconditionally close holding brake) has a higher priority than via BI: p0855 (unconditionally
open holding brake).
p0856[0...n] BI: Enable speed controller / n_ctrl enable
Access level: 3
Can be changed: T
Unit group: -
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: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: r0898
Note: If "enable speed controller" is withdrawn, then an existing brake will be closed.
If "enable speed controller" is withdrawn, the pulses are not suppressed.
p0857 Power unit monitoring time / PU t_monit
Access level: 3
Can be changed: T
Unit group: -
Min
100.0 [ms]
Description: Sets the monitoring time for the power unit.
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, fault F07802 is output.
Dependency: Refer to: F07802, F30027
Notice: The maximum time to precharge the DC link is monitored in the power unit and cannot be changed. The maximum
precharging duration depends on the power unit.
The monitoring time for the precharging is started after the ON command (BI: p0840 = 0/1 signal). Fault F30027 is
output when the maximum precharging duration is exceeded.
Note: The factory setting for p0857 depends on the power unit.
The monitoring time for the ready signal of the power unit includes the time to precharge 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.
p0858[0...n] BI: Unconditionally close holding brake / Uncond close brake
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for the command "unconditionally close holding brake".
Dependency: Refer to: p0855
