•
Position control is not disabled when an active measuring system with indirect encoder
(motor encoder) is used:
MD31040 $MA_ENC_IS_DIRECT = 0
If a measuring system with a direct encoder (load encoder) is active, position control is
deactivated:
DB31, ... DBX61.5 = 0,
because the induction flux to the load is interrupted and closed-loop position control is no
longer possible.
•
If positioncontrolled operation is not possible, it can be disabled by
resetting "Servo enable":
DB31, ... DBX2.1 = 0
.
•
Mechanical switchover of the gear step on the machine.
No oscillation motion is required from the drive.
NC/PLC IS:
DB31, ... DBX18.5 (Oscillation enable)
and
DB31, ... DBX18.4 (Oscillation via PLC)
should not be set.
In principle, oscillation movement is still possible at this point.
•
Writing of NC/PLC IS:
DB31, ... DBX16.0-16.2 (Actual gear step A to C)
by the PLC.
•
After signal:
DB31, ... DBX16.3 (Gear step changed),
the last movement to be active is continued, if available.
For indirect encoders (motor encoders), the homing status is cleared:
DB31, ... DBX60.4/5 = 0.
The spindle is in speed control mode and NC/PLC IS:
DB311, ... DBX84.7 (Openloop control mode)
is output.
