A0003 Communication phase 3
Communication Phase 4
Supported by Firmware Variant:
Supported by Supply Unit:
Communication phase 3 means that the drive is in the restricted
parameterization mode. In this mode, as in the parameterization mode
(phase 2), many parameters can still be written that cannot be written any
more in communication phase 4 (operating mode). Communication
parameters cannot be written in phase 3.
During the communication phase 3 the control panel of the drive reads
In order to get to communication phase 3 the master, in the case of drives
with field bus and SERCOS interfaces, sets "communication phase 3" via
the master communication interface. Another possibility to switch to
Communication phase 3 transition check command.
Before it is possible to switch to communication phase 4 it is necessary to
execute the S-0-0128, C0200 Communication phase 4 transition
check command. Among other things the drive, during the transition
check, checks the parameters required for communication phase 4 for
After successful execution of the transition check command the master
switches the drive to communication phase 4 (in the case of field bus and
SERCOS devices) or the drive automatically switches to phase 4 at the
end of the transition check command.
