Control Word
PNU 330 ć uint16 rw
Description Control word: 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. B/10
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 field bus interface:
Ĉ Reset Fault" (bit 7) as per DS402 processing with positive edge, but via CI
the level will be evaluated.
Ĉ START bit (bit 4) with homing 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 field bus.
Ĉ Switch to Operation enable" may simultaneously contain action−triggering
bits (START, Jog, ...).
Ĉ Shortened status transitions:
ć Command Operation disable" or Switch on" (same coding):
Status OPERATION ENABLE" −> READY TO SWITCH ON".
Status READY TO SWITCH ON" −> 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"
Typical values for access via the CI interface: see Tab. B/11
