3.13State 13: Freezing
Clearing the /Freeze bit in the control word initiates a quick stop. After the motion is stopped
the drive rests position controlled. Setting the bit again the drive will finish the frozen motion
(e.g. if it was a VAI command). Curve motion can be frozen but not restarted by releasing
this bit, setting the bit again the motor moves at the target position of the last VAI command,
if never used a VAI command it will go to the initial position.
3.14State 14: Error Behaviour Quick Stop
Most of the errors, which can occur during an active motion, cause a quick stop behavior to
stop the motion. After the quick stop is finished the motor is no longer position controlled.
3.15State 15: Going To Position
Setting the Go To Position bit in the control word, the serveo moves to the defined position,
recommendable for example, after an error, to move to a defined position again.
3.16State 16: J
Setting the Jog Move + bit in the control word, the motor moves either by a defined position
increment or to the maximal position with a limited speed. Releasing the bit will stop the
motion.
3.17State 17: Jogging -
Setting the Jog Move - bit in the control word, the motor moves either a defined position
decrement or to the minimal position with a limited speed. Releasing the bit will stop the
motion
3.18State 18: Linearizing
The linearizing state is used to correct position feedback parameters, to improve the linearity
of the position feedback.
3.19State 19: Phase Searching
The phase search is only defined for three phase EC motors with hall switches and ABZ-
sensors to find the commutation offset for to the sensor. It cannot be guaranteed that this
feature will work for all kinds of EC motors. The found offset can be found in the variable
section Calculated Commutation Offset (UPID: 1C1Bh), and has to be set manually to he
parameter Phase Angle (UPID 11F2h).
3.20State 20: Special Mode
The Special Mode is available only on the B1100 drives. In this state the current command
mode over the analog input is available. For using this mode see the [4].
3.21Building the Control Word
The Control Word can be accessed bit by bit from different sources with different priorities.
The highest priorities have the bits that are forced by parameters. The second highest priority
has the control panel of the LinMot-Talk software, if logged in with the SW. The next lower
priorities have the bits that are defined on the X4 IOs as control word input bits. The lowest
priority have bits which are set over the interface (normally a serial fieldbus connection), so in
the Ctrl Word Interface Copy mask all bits can be selected, without causing any problems,
but bits which should not be accessed through the interface can be masked out.
