Times of the brake control

The times of the brake control can be influenced by the following objects:
Index Id-Text Name
0x2516 co22 brake ctrl open delay
0x2517 co23 brake ctrl open time
0x2518 co24 brake ctrl closing delay
0x2519 co25 brake ctrl closing time

Status of the brake control

The status of the brake control can be displayed via the following object:
Index Id-Text Name
0x2104 st04 brake ctrl status

Description
The modulation is enabled in state "start operation active" and speed = 0
is preset. Subsequently, the setpoint of the brake control (CMD) is set to
1.
After the assumed state of the brake (Val) has reached value 1 (open
brake), the state machine changes to "Operation enabled".
Speed shutdown to 0 in state "shutdown operation active" depending on
the selected ramp (standard ramp) or
reaction ramp). Subsequently, the setpoint of the brake control (CMD) is
set to 0.
After the assumed condition of the brake (Val) has reached value 0 (brake
closed), the state machine changes to "ready to switch on".
Speed shutdown to 0 in state "disable operation active" depending on the
selected ramp (standard ramp) or
action ramp). Subsequently, the setpoint of the brake control (CMD) is set
to 0.
After the assumed condition of the brake (Val) has reached value 0 (brake
closed), the state machine changes to „switched on".
The speed is set to pn47 fault reaction ref velocity
tive" state. Subsequently, the setpoint of the brake control (CMD) is set to
0.
After the assumed condition of the brake (Val) has reached value 0 (brake
closed), the state machine changes to "fault".
The states "shutdown operation active", "disable operation active" and "fault
reaction active" are only carried out with the appropriate setting of the state
machine.
➢ Make sure that the appropriate settings have been made in object
state machine properties.
