Machine data
2.4 Axis-specific machine data
Description: Maximum time delay for removal of "controller enable" after faults. The speed
enable (controller enable) of the drive is removed internally within the con-
troller after the set delay time, at the latest.
The delay time entered becomes active as a result of the following events:
• Errors that lead to immediate stopping of the axes
• Removal of the interface signal DB380x DBX2.1 (Controller enable) from
the PLC
As soon as the actual speed reaches the standstill range (MD36060
$MA_STANDSTILL_VELO_TOL), the "controller enable" for the drive is removed.
The time set should be long enough to enable the axis / spindle to brake down
to a standstill from maximum traversing velocity or maximum speed. If the
axis / spindle is stationary, the "controller enable" for the drive is
removed immediately (i.e. the time defined in MD36620
$MA_SERVO_DISABLE_DELAY_TIME is terminated prematurely).
Application example(s):
Speed control of the drive should be retained long enough to enable the axis
/ spindle to brake down to standstill from maximum traversing velocity or
maximum speed.
Notice:
If the cutout delay controller enable is set too short, controller enable
will be removed although the axis/spindle is still moving. This axis/spindle
then coasts down without power (which may be appropriate for grinding wheels,
for example); otherwise the time set in MD36620 $MA_SERVO_DISABLE_DELAY_TIME
should be longer than the duration of the braking ramp for error states
(MD36610 $MA_AX_EMERGENCY_STOP_TIME).
