ADIMPRES (P177)
Resolution of the additive handwheel.
These values are only applied when bit 12 of parameter ADIMPG has been set to ·1·.
SERCDEL1 (P178)
It allows setting the Sercos transmission delay when working at 8 MHz or at 16 MHz. The default
delay is 400µs and this parameter may be used to set a delay of 600µs.
Setting a longer delay at the bus permits increasing the amount of data going through the fast
channel. This may be necessary, for example, when having set many PLC parameters (SRR700
to SRR739) that define the fast channel or when accessing variables of several drives from the
oscilloscope.
In any case, if the CNC detects a limit situation in the bus capacity, it will show a message suggesting
to increase this parameter.
When changing the parameter value from 0 (same as 400 µs) to 600 on a machine using the fine
adjustment, i.e. with "zero following error", we recommend to slightly increase the value of the
DERGAIN parameter (when ACFGAIN = YES) to compensate for the additional 200 microsecond
delay.
SERCDEL2 (P179)
Not used.
EXPLORER (P180)
It sets how to access the explorer.
REPOSTY (P181)
It allows selecting the repositioning mode.
MAXOFFJ (P182)
This parameter indicates the maximum incremental value allowed for Y axis wear compensation
(it is programmed in mm or in inches). Default value: 0.5.
Value Meaning
0 0.001 mm or 0.0001 inch.
1 0.01 mm or 0.001 inch.
2 0.1 mm or 0.01 inch.
Default value: 0
Value Meaning
0 It sets a delay of 400 µs.
400 It sets a delay of 400 µs.
600 It sets a delay of 600 µs.
Default value: 0 (400 µs.)
Value Meaning
0 It is accessed using the explorer softkey of the utilities, execute, simulate or edit modes.
1 It is accessed directly from the utilities, execute, simulate or edit modes.
Default value: 1
Value Meaning
0 It activates the basic repositioning mode
1 It activates the extended repositioning mode
Default value: 1
