7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
1625
Default value
0
Input of ON (pickup) delay time for setting of the message if the threshold (with hysteresis) is
exceeded (see diagram under MD 1620).
Note:
Changes to machine data MD 1625 and MD 1626 (Delayed dropout variable message
function) has an effect on a time monitoring function which is already in progress. The
monitoring function is initialized with the newly entered time data.
1626
Delayed dropout variable message function
Default value
0
Input of OFF (dropout) delay time for resetting of the message if the monitored quantity drops
below the threshold (with hysteresis) (see diagram under MD 1620).
Note:
Changes to machine data MD 1625 (Pickup delay variable message function) and MD 1626
has an effect on a time monitoring function which is already in progress. The monitoring
function is initialized with the newly entered time data.
1630
Default value
550
Input of response threshold of DC link voltage; if the voltage drops below this value, only the
DC link voltage is monitored (motor temperature monitoring is discontinued). If the voltage
rises above the threshold value again, then the normal monitoring function is resumed.
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
1631
Default value
450
Input of response threshold of DC link voltage; if the voltage drops below this value, a drive
defined as a generator axis (MD 1636) switches over to generator mode.
Note:
This machine data is described under the additional function "Extended shutdown and
retraction (G420...G426)", see Programming Guide 840C.
