2.2 Safety Precautions
NOTICE
Damage due to impermissibly high forces and torques!
Impermissibly high forces and torques that are applied to the motion platform (see Figure 1)
can damage the Q-821.
Do not exceed the maximum permissible forces and torques that are allowed to act on the
motion platform (see Figure 2 for the coordinate system):
- Maximum force in Z: 2 N

NOTICE
Damage from collisions during the reference move!
The Q-821 moves unpredictably during a reference move. The approach of the reference
position always takes place via the negative or positive hard stop of the linear drives. Soft limits
that have been set for the motion platform of the Q-821 with the NLM and PLM commands are
ignored during the reference move. In addition, no collision check or prevention takes place.
As a result, collisions are possible between the Q-821, the load to be moved, and the
surroundings. Collisions can damage the Q-821, the load to be moved, and the surroundings.
Make sure that no collisions between the Q-821, the load to be moved, and the
surroundings are possible during the reference move of the Q-821.
Make sure that the installation space is sufficient to allow motion along the complete
travel range of each axis.
Do not place any objects in areas where they can be caught by moving parts during the
reference move.
After a successful reference move, supply a command for the corresponding target
position in order to return to the reference position (default: zero position) from any given
position.
Do not start a new reference move, but send a command line as follows:
MOV X 0 Y 0 Z 0 U 0 V 0 W 0
.
NOTICE

6 Start-Up and Operation
6.1 General Notes on Start-Up
NOTICE
Overheating during continuous operation!
The highest velocity is achieved at maximum operating frequency; however, the Q-821 can
overheat during continuous operation as a result.
Observe the recommended operating time according to the operating frequency in step
mode (p. 26).
Ensure sufficient ventilation at the place of installation.
NOTICE
Damage from collisions during the reference move!
The Q-821 moves unpredictably during a reference move. The approach of the reference
position always takes place via the negative or positive hard stop of the linear drives. Soft limits
that have been set for the motion platform of the Q-821 with the NLM and PLM commands are
ignored during the reference move. In addition, no collision check or prevention takes place.
As a result, collisions are possible between the Q-821, the load to be moved, and the
surroundings. Collisions can damage the Q-821, the load to be moved, and the surroundings.
Make sure that no collisions between the Q-821, the load to be moved and the
environment are possible during the reference move of the Q-821.
Make sure that the installation space is sufficient to allow motion along the complete
travel range of each axis.
Do not place any objects in areas where they can get caught by moving parts during the
reference move.
After a successful reference move, supply a command for the corresponding target
position in order to return to the reference position (default: zero position) from any given
position.
Do not start a new reference move, but send a command line as follows:
MOV X 0 Y 0 Z 0 U 0 V 0 W 0
NOTICE
Incorrect configuration of the controller!
The configuration data used by the controller (e.g. geometrical data and servo-control
parameters) must be adapted to the Q-821. If incorrect configuration data is used, the Q-821
can be damaged by uncontrolled motions or collisions. The configuration data is adapted
before delivery.
Check whether the controller matches the Q-821. A label on the rear panel of the
controller indicates for which Q-821 the controller is intended.
When you have established the communication via TCP/IP, send the CST? command. The
response shows the Q-821 to which the controller is adapted.
Only operate the Q-821 with a controller whose configuration data is adapted to the
Q-821.

NOTICE
Damage from collisions!
Collisions can damage the Q-821, the load to be moved and the environment.
Make sure that no collisions between the Q-821, the load to be moved and the
environment are possible in the work space of the Q-821.
Do not place any objects in areas where they can get caught by moving parts.
If the controller malfunctions, stop the motion immediately.
NOTICE
Damage from unintentional position changes!
The limit value for the load of the Q-821 determined with the simulation program is only valid
when the servo mode is switched on for the axes of the motion platform. The maximum
holding force when the servo mode is switched off is based on the self-locking of the actuators
in the struts of the Q-821.
The maximum holding force with the servo mode switched-off is lower than the limit value
when the servo mode is switched on (see “Data Table” on p. 25).
When the actual load of the Q-821 exceeds the maximum holding force based on the self-
locking of the actuators, unintentional position changes of the Q-821 can occur in the following
cases:
Switching off the controller
Rebooting the controller
Switching off the servo mode for the axes of the Q-821
As a result, collisions are possible between the Q-821, the load to be moved, and the
environment. Collisions can damage the Q-821, the load to be moved, or the environment.
Make sure that the actual load of the motion platform of the SpaceFAB does not exceed
the maximum holding force based on the self-
locking of the actuators before you switch off
the servo mode, reboot or switch off the controller.

NOTICE
Damage from uncontrolled motion of the Q-821!
In the following cases, the velocity and acceleration of the motion platform of the Q-821 are
not specified by the trajectory generator of the controller:
The Trajectory Source parameter (ID 0x19001900) has the value 1.
The Trajectory Source parameter has the value 0, and the Q-821 (axes X, Y, Z, U, V, W) is
still moving while a new motion command is sent. The previous target position is thereby
overwritten without the velocity and acceleration of the motion platform of the Q-821
being recalculated.
The platform of the Q-821 then moves on an undefined path. On this undefined path, collisions
with the environment of the Q-821 are possible. Collisions can damage the Q-821, the load to
be moved and the environment.
When the Trajectory Source parameter has the value 1:
Only set target positions whose distance from each other is maximally as large as the value
of the Path Control Step Size (mm) parameter (ID 0x19001504) with consecutive MOV
commands.
When the Trajectory Source parameter has the value 0:
Avoid sending new target positions while the Q-821 (axes X, Y, Z, U, V, W) is still moving.
If new target positions have to be sent while the Q-821
is still moving (axes X, Y, Z, U, V, W):
Only use motion commands to set target positions that maximally deviate from the current
position by the value of the Path Control Step Size (mm) parameter (ID 0x19001504).
INFORMATION
The communication interfaces of the controller (user interface, TCP/IP) are active at the same
time. Commands are executed in the order that the complete command lines arrive. The
simultaneous use of several communication interfaces can cause problems with the PC
software, however.
Always only use one interface of the controller.
INFORMATION
When switched on or rebooted, the controller automatically switches on the servo mode for all
axes. When the servo mode is switched off for the axes of the motion platform of the Q-821 (X,
Y, Z, U, V, W), it is automatically switched on when the reference move is started.
INFORMATION
For the axes of the motion platform of the Q-821 (X, Y, Z, U, V, W), motions can only be
commanded after a successful reference move (also referred to as "initialization").
A common reference move is always performed for the axes of the motion platform of the
Q-821 (X, Y, Z, U, V, W).

2. Start up the controller (see user manual of the controller).
3. Start up the software (see software manual).
6.2.1 Performing a Reference Move
INFORMATION
Soft limits that have been set for the motion platform of the Q-821 with the NLM and PLM
commands are ignored during the reference move.
The linear drives of the Q-821 have optical reference point switches without direction sensing.
The approach of the reference position always takes place via the negative or positive hard stop
of the linear drives.
After a reference move each axis of the Q-821 is in center position.
See the user manual of the controller for more information abour the FRF command and
reference moves.
