MD10089 $MA_SAFE_PULSE_DIS_TIME_BUSFAIL
MD36961 $MA_SAFE_VELO_STOP_MODE
$MA_SAFE_IPO_STOP_GROUP
Grouping, safety IPO response
Min. input limit: 0
This MD is only effective for Safety Integrated axes/spindles.
It influences the channel-wide IPO response distribution of Safety Integrated.
0 = default setting:
All other axes/spindles in the channel are notified of the IPO stop response of this axis.
1 =
For internal stops, the axes and machining spindles, interpolating with the axis involved, are
also additionally influenced via the initiated safety alarms. On the other hand, other axes/spin‐
dles in the channel continue to operate without any disturbance.
For external stops (without alarm) all of the other axes/spindles remain unaffected by the safety
axis/spindle stop. This allows, for example, the pulses of the spindle to be safely cancelled
(using an external STOP A). This means that the spindle can be manually rotated and the
axes can still be safely monitored while it is moving.
If, in some machining situations, the other axes/spindles should stop together with the safety
axis/spindle, then the user is responsible in implementing this using PLC or synchronized
action logic combinations.
$MA_SAFE_PARK_ALARM_SUPPRESS
Alarm suppression for parking axis
Min. input limit: -
This MD is only effective for Safety Integrated axes/spindles.
0: Default setting:
Alarms 27000/A01797 are displayed when selecting parking.
1:
Alarms 27000/A01797 are not displayed when selecting parking. This is necessary for axes
that are disconnected from one another on the encoder side during the machining process
(e.g. dressing axes). Alarms are displayed when parking operation is subsequently deselected.
$MA_SAFE_BRAKETEST_TORQUE
Holding torque, brake test (NC-controlled)
