MD37052
The machine parameter:
MD37052 FIXED_STOP_ALARM_REACTION
does not result in disconnection of the drive from the power supply when an alarm is
generated, as interface signal "Mode group ready" DB11,... DBX6.3 remains active.
Bit value=0:
The alarms have an effect on FXS (drive becomes disconnected as previously).
IS "Mode group ready" DB11, ... DBX6.3 is reset.
Bit value=0:
The alarms have no effect on FXS.
IS "Mode group ready" DB11, ... DBX6.3 remains active.
Bit 0: Alarm 20090
Bit1: Alarm 20091
Bit 2: Alarm 20092
Bit 3: Alarm 20093
Bit 4: Alarm 20094
2.1.5 Supplementary conditions for expansions
Response to pulse blocking
The cancellation of the pulse enable, either by terminal 663 or by NST "Pulse enable"
(DB31, ... DBX21.7) is referred to as pulse blocking below.
The machine parameter:
MD37002 FIXED_STOP_CONTROL
can be used to influence the interaction of "travel to fixed stop" and pulse blocking.
Bit 0: Response in case of pulse blocking at stop as follows:
Bit 0 = 0
Bit 0 = 1
