In this context, the brake management mode is as follows:
•
•
•
•
•
•
•
•
The brake relay is opened at initialization ("brake relay" open = brake closed in positive safety).
A system protective device is implemented to prevent the brake from opening when the torque is
disengaged or when there is no power.
If a torque disengagement demand is requested by a user command, the brake relay is opened
prior to the torque disengagement.
The management of the emergency open command for the brake relay causes the following:
- a speed demand of zero,
- the immediate opening of the brake relay,
- a delayed torque disengagement (100 ms delay for dynamically braking the axis).
The management of the brake close command statement (by user command) causes the following:
- a speed demand of zero,
- waits for the speed to fall below 60 rpm before sending the open command to the brake relay,
- a delayed torque disengagement (delay depending on the time for the effective closing of the
brake: brake_ton).
The management of the brake open command statement (by user command) causes the following:
- brake relay closed only if there is power and the torque is validated.
When the brake supply is removed, the following occurs:
- a speed demand of zero,
- a delayed torque disengagement (delay depending on the time for the effective closing of the
brake: brake_ton).
When a serious fault is detected, the following occurs:
- the torque is immediately invalidated,
- the brake relay is immediately opened.
5.2.4.4 Case No.4: Brake present and managed by the drive (specific case)
The brake management mode is the same as in case no.3 except for one thing: there is no system
protective device to prevent the brake from opening when the torque is disengaged or when there is no
power.
•
•
•
The brake is managed by the drive:
[brake_management = 1]
The brake is automatically opened when power is detected: [brake_init = 1],
or when the auxiliary power is detected:
[brake_init = 2],
or not at all:
[brake_init = 0].
The brake can be opened when the torque is not applied or when there is no power:
[brake_option = 0]
When all entries are correctly filled in, click on the OK button.
