DB31, ... DBX2.1 (servo enable)
Setting the servo enable closes the machine axis position control loop. The machine axis is
in position control mode.
DB31, ... DBX2.1 == 1
Canceling the servo enable opens the machine axis position control loop and, subject to a
delay, the machine axis speed control loop:
DB31, ... DBX2.1 == 0
Activation methods
The closed-loop servo enable for a machine axis is influenced by:
•
PLC user program by means of the following NC/PLC interface signals:
–
DB31, ... DBX2.1 (servo enable)
–
DB31, ... DBX21.7 (pulse enable)
–
DB31, ... DBX93.5 (drive ready)
–
DB10, DBX56.1 (EMERGENCY STOP)
•
NCK-internal
Alarms that trigger cancellation of the servo enable on the machine axes. Alarms, which
cancel the servo enable, are described in:
References:
/DA/Diagnostics Manual
Canceling the servo enable when the machine axis is at standstill:
•
The machine axis position control loop opens
•
DB31, ... DBX61.5 = 0 (position controller active)
Canceling the servo enable when the machine axis is in motion:
If a machine axis is part of an interpolatory path movement or coupling and the servo enable
for this is canceled, all axes involved are stopped with a fast stop (speed setpoint = 0) and
an alarm is displayed:
Alarm: "21612 Servo enable reset during movement"
•
The machine axis is decelerated taking into account the parameterized temporal duration
of the brake ramp for error states with a fast stop (speed setpoint = 0):
MD36610 $MA_AX_EMERGENCY_STOP_TIME (max. time duration of the braking ramp
in event of errors)
