Brake off delay (Brake off delay):
756
This parameter is used to specify the delay time between activating motor control and
opening the mechanical brake (output 4). This is necessary to avoid loosing the load
because of the reaction time of the mechanical brake.
Setting range:
0 ... 5000 msec.
The value must be set according to the reaction time of the mechanical brake.
757 Marker monitor
This parameter specifies the behavior when markers are missing in Marker Synchronizing
mode (par. 725 = 2 or 5).
Setting range:
0 = Output 2, fault is set when "not accuracy" for x number of markers (x = par. 734).
1 = Output 2, fault is set when "not accuracy" for x number of markers (x = par. 734) OR
when x number of markers are missing.
2 = Output 2, fault is set when "not accuracy" for x number of markers (x = par. 734) and
Output 2, fault is set and the error handler is called when x number of markers are
missing.
NOTE:
This function can only be used if marker windows are used (par. 751 and 752).
Resync.
758
With resync active synchronisation will remain active while the slave is stopped (Input 1
and/or Input 27 = 0). The actual synchronizing error will be corrected with the set velocity
and acceleration when restarting synchronisation.
Setting range:
0 = inactive
1 = active
Synchronous operation, program 2:
775
Track error (read only): This parameter indicates the actual PID error during
synchronization (same as par. 797 in test-run mode).
