10.41 Deactivation of monitoring functions

WARNING

If monitoring functions are deactivated, there may be a risk to the safety of operating personnel or of substantial property damage if a fault or error actually occurs!

P820	Deactivation of fault messages
*	The numbers of all fault messages to be deactivated must be entered in this
	parameter. Fault numbers can be entered in any order. 0 must be entered
	for any unused indices of the parameter.
	Factory setting:
	i001	= 7	(overvoltage)
	i002	= 18	(short circuit at binary outputs)
	i003	= 31	(monitoring of speed controller)
	i004	= 35	(drive blocked)
	i005	= 36	(armature current cannot flow)
	i006	= 37	(I2t motor monitoring function has responded)
	i007 to i099 = 0
P821	Deactivation of alarms
*	The numbers of all alarm messages to be deactivated must be entered in
	this parameter. Alarm numbers can be entered in any order. 0 must be
	entered for any unused indices of the parameter.

10.42 Compensation values

r824	A7006 compensation values
	These data contain compensation values for the analog section of
	electronics board A7006
P825	Offset compensation for actual field current channel
	These data contain compensation values for the actual field current sensing
	function. They are automatically set during "Restore factory settings"
	(P051=21) and during the automatic offset compensation run (P051=22).
P826	Correction of natural commutation timing
(G163)	If there is a variation in the armature current peak value (in spite of a
	constant firing angle), it can be corrected by offsetting the firing angle
	reference time of the appropriate line phase in parameter P826. One line
	phase (UV, UW, VW, VU, WU, WV) is assigned to each parameter index
	(i001 to i006).
	Increasing the parameter setting by a value of 1 corresponds to an increase
	of 1.333 µs in the firing angle (0.024 degrees at 50Hz line frequency),
	consequently reducing the armature current peak in the appropriate line
	phase.
	P826 is automatically set during the optimization run for precontrol and
	current controller (armature and field) (P051=25) (only when U800=0; when
	U800=1 or 2, parameters P826.001 to 006 are set to 0).
	Caution:
	Even an asymmetrical system causes variations in the magnitude of
	armature current peaks. However, the system asymmetry may also change.
r827	Internal diagnosis
	i001:	Number of write access operations to EEPROM
	i002:	Number of Page-Write access operations to EEPROM
	i003:	Counter for DUAL-PORT RAM timeouts
r828	MLFB data
	These data contain details about the power section design (model)
r829	A7001 compensation values
	These data contain compensation values for the analog section of
	electronics board A7001
