Control word
DS402 / CI 6040h 00h Var uint16 rw
Description Modify the current controller status or trigger an activity.
As status modifications require a certain amount of time, all status modificaĆ
tions triggered via the control word must be read back via the status word
(6041h). Further commands cannot be written via the control word until the
requested status can be read in the status word.
Bit assignment: see Tab. C/2.
Description of the DS402 finite state machine: see section C.1.
Special features
for access via the
CI interface If this object is accessed via the CI interface, the following special features
must be observed compared with access via the fieldbus interface:
Ĉ Reset fault" (bit 7) as per DS 402 processing with positive edge, but via CI
the level will be evaluated.
Ĉ START bit (bit 4) with reference travel and positioning: as per DS402 edge−
triggered, but via CI the level will be evaluated. 0−set interpreted as stop.
Ĉ HMI access locked" (bit 14): only accessible via the fieldbus.
Ĉ Switch to Operation enable" may simultaneously contain action−triggering
bits (START, Jog, ...).
Ĉ Shortened status transitions:
ć Operation disable" command or Switch on" (same coding):
OPERATION ENABLE" status −> READY TO SWITCH ON".
READY TO SWITCH ON" status −> SWITCHED ON".
ć Disable voltage" command (bit 1 = 0, rest irrelevant) ć all states
−> READY TO SWICH ON".
ć Operation enable" command (all states) −> OPERATION ENABLE".
ć Voltage disable" and Quick stop" commands −> READY TO SWITCH ON"
Bit assignment: see Tab. C/2.
Typical values for access via the CI interface: see Tab. C/3.
