p0854[0...n] BI: Control by PLC/no control by PLC / Master ctrl by PLC
CU240B-2 DP Access level: 3
CU240E-2 DP
Can be changed: T
CU240E-2 DP F
Units group: -
Min
-
Description: Sets the signal source for the command "control by PLC/no control by PLC".
For the PROFIdrive profile, this command corresponds to control word 1 bit 10 (STW1.10).
BI: p0854 = 0 signal
No control by PLC
BI: p0852 = 1 signal
Control by PLC.
Caution: When "master control from PC" is activated, this binector input is ineffective.
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: This bit is used to initiate a response for the drives when the control fails (F07220). If there is no control available,
then binector input p0854 should be set to 1.
If a control is available, then STW1.10 must be set to 1 (PZD1) so that the received data is updated. This applies
regardless of the setting in p0854 and even in the case of free telegram configuration (p0922 = 999).
p0855[0...n] BI: Unconditionally release holding brake / Uncond open brake
Access level: 3
Can be changed: T
Units 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 (uncondition-
ally open holding brake).
p0856[0...n] BI: Speed controller enable / n_ctrl enable
Access level: 3
Can be changed: T
Units 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: 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Note: If "enable speed controller" is withdrawn, then an existing brake will be closed.
If "speed controller enable" is withdrawn, the pulses are not suppressed.
