| − | Drive OFF: When switching from 1 to 0: drive is decelerated as best as possible, followed by disabling of the torque at ''n'' <sub>min</sub>. The power stage can remain in an activated state (only possible when bit 14=1).

This property allows the user to read the control word being sent to the drive.
From version 0.4.17.2 property is read-write for EtherCAT and CAN systems.
EtherCAT and CANOpen systems:
Value written to DriveControl is transferred "as is" to drive via drive control (CANOpen object 0x6040/0) in case this object is mapped to PDO.
Query of DriveControl returns its shadow value in 16 upper bits.
The control word is transmitted in each motion bus cycle cycle, and is composed of 16 bits.
