When the brake control is activated, when the status changes from
”ready” to ”operation enabled”, the brake is opened. At the same time,
the pulses are enabled and the axis goes into closed–loop controlled
operation without a traversing task. In the “Positioning” mode (P700 =
2), the “holding controller” (P57) is switched-in with the factory default
setting of P56.2 = 0 (from SW 1.3). In the “speed setpoint” mode
(P700 = 1), it is switched-over to “P gain n-controller standstill” (P54).
In order to give the brake the necessary time to mechanically open, the
drive starts after the brake opening time (P58).
The drive goes into the ”operation enabled” status after the time in P58
has expired.
The brake opening time should be selected, so that after the ”controller
enable” is issued, the speed controller becomes active when the motor
holding brake opens. For all other settings, the control acts against the
brake.
