In encoder-only systems (in which no digital Hall sensors are present), the

commutation is calculated only once after power up upon the first MO=1
command. The motor moves a few encoder counts during the automatic
commutation search.

When the brake function is enabled, the dedicated output is released after the

duration defined in BP[N]. During this time, all motion reference commands are
ignored.

After a motor fault (MF>0), the motor can be re-enabled only when the cause of

the fault is no longer present.

If MO=1 fails with the “Amplifier not ready” error code (EC=66), the exact

reason for the fault can be found by querying the MF command.

MO=0 disables the motor for 200 sampling times (about 10 milliseconds) until a

new MO=1 can restart the motor.

In the “Ready to switch on”, “Switch on disabled” and “Fault” states (refer to the

Elmo CANopen Implementation Manual), MO=1 is blocked and returns an error.
These states can be command controlled only by a CAN master using the DS402
standard control word (object 0x6040).

Setting MO=1 in the “Switched on” CAN state transfers the state of the state

machine to “Operation enabled.” Setting MO=0 in “Operation Enabled” or
“Quick stop active” state will transfer the state machine to “Switched on.” (Refer
to CAN object 0x6040 in the Elmo CANopen Implementation Manual).
