6040h, 6840h Controlword - AxisX

The control commands are built from the logical combination of the bits in the controlword and external signals (example: enable output stage).

Controlword bits 11-15 mode

Controlword bits 11-15 are defined to be manufacturer specific by the DS402 standard. For AKD2G, specific modes can be set for each bit that defines the behavior. See AXIS#.CANOPEN​.CONTROLBIT##.MODE for available mode descriptions.

Mode-dependent bits in the controlword

The following table shows the mode-dependent bits in the controlword. Only manufacturer-specific modes are supported at present. The individual modes are set by object 6060h, 6860h Modes of operation - AxisX.

Operation Mode No. Bit 4 Bit 5 Bit 6 Bit 9
Analog velocity FEh reserved reserved reserved reserved
Analog torque FFh reserved reserved reserved reserved
Cyclic sync position Mode (csp) 08h reserved reserved reserved reserved

Electronic Gearing FDh reserved reserved reserved reserved
Homing mode (hm) 06h Start homing operation reserved reserved reserved
Profile position mode (pp) 01h New set-point Use new set-point immediately

0 - Absolute move

1 - Relative move

Blend / only the fly move once target position is reached
Profile torque mode (tq) 04h reserved reserved reserved reserved
Profile velocity mode (pv) 03h reserved reserved reserved reserved

Description of the remaining bits in the controlword

The remaining bits in the controlword that are not used for drive state machine commands or operation mode specific commands are used for special operations:

Bit 8 – Pause/Halt: If bit 8 is set, then the drive halts (pauses) in all modes. The set-points (speed for homing or jogging, motion task number, setpoints for digital mode) for the individual modes are retained.
