h) Bit 6 establishes whether the positioning should be carried out absolutely (0) or relatively (1).
–
Command:
=604000:001F start absolute positioning or
–
Command:
=604000:005F start relative positioning
5. After positioning has been ended, the status of the controller must be reset so a new positioning
can be started.
–
Command:
=604000:000F bring controller into “Ready” state.
Example: “Homing mode” via the RS232 interface
With the CAN access simulated via the RS232 interface, the motor controller can also be operated in
the CAN “Homing mode”. The following describes the sequence in principle.
1. Conversion of the controller enable logic
2. The controller enable logic can be changed via the CAN control word (COB 6010_10). Since the
simulation of the CAN interface can be completely taken over via the RS232 interface, the enable
logic can also be converted to DINs + CAN.

Command:
=651010:0002
3. As a result, the release can be granted via the CAN control word (COB 6040_00).
–
Command:
=604000:0006 command “shutdown”
–
Command:
=604000:0007 command “switch on/disable operation”
–
Command:
=604000:000F command “Enable operation”
4. Activation of the “Homing mode”
5. The reference mode is activated via the CAN control word (COB 6060_00, Mode of Operation).
–
Command:
=606000:06
Homing mode
6. Start homing
7. Homing is started via the CAN control word (COB 6040_00).
8. Controller enable is controlled via bit 0 … 3.
9. Homing is started via a rising edge at bit 4.
–
Command:
=604000:001F
10.After homing has been ended, the status of the motor controller must be reset.
–
Command:
=604000:000F bring controller into “Ready” state.
