2.1 Control mode
Controlword/Statusword
By changing [Controlword (Obj. 6040h)], control commands can be given to the servo amplifier. The control status can also be
checked with [Statusword (Obj. 6041h)].
Some bits of [Controlword (Obj. 6040h)] and [Statusword (Obj. 6041h)] vary depending on the control mode. The bits that vary
depending on the control mode are listed in the following tables.
