Fieldbus control through the embedded fieldbus interface (EFB)
385
The halt mode is controlled with bit 8 of the CiA 402 control word. When the halt
bit is set during the OPERATION ENABLED state, the drive stops and the state
machine remains in the OPERATION ENABLED state. When the bit is reset, the
drive starts running again. In all modes supporting the halt function, CiA 402
Status Word bit 10 (target reached) is set when the drive is stopped.
Note
: The drive may not necessarily stop completely as it is still the in running
(OPERATION ENABLED) state.
The following table summarizes the drive features used to perform the ramp
stop during the halt function, as well as the different halt option codes
supported by each CiA 402 operating mode. The halt option code is selected by
CANopen object 605Dh.
Status Word for the CiA 402 profile
Status word of the CiA 402 profile can be read from the object 6041h.The table
below shows the fieldbus Status Word for the CiA 402 control profile. The
embedded fieldbus interface converts the drive Status Word into this form for
the fieldbus.
