Control Outputs:
Ready
(terminal 21)
This announces that the unit is ready to run. On power up, this output is
"Low" for about one second to allow the power supply to settle, and then
switches to "High". The output goes low also for the duration of parameter
storage to the EEPROM.
When "High", the unit could not detect a system fault itself, but this is not a
guarantee for fault-free operation!
Alarm
(terminal 22)
The alarm output signals that the preset tolerance band has been exceeded in
one direction or the other, as specified by the parameter "Alert".
Out Sync
(terminal 23)
This output goes high when, despite of full analogue correction, the
synchronization can no more be maintained. Mechanical or electrical
problems can cause this situation (e. g. current limit of the drive).
Index o.k.
(terminal 24)
When High the slave index pulses are inside the window set by parameter
“Index Window”, with respect to the position of the Master index pulse and
the phase displacement set to register "Phase Offset".
