MACHINE PARAMETERS
Spindle parameters
(SOFT M: V15.3X)
(S
OFT T: V16.3X)
·146·
DIFFBACK (P14)
Indicates whether the feedback device uses differential signals (double ended) or not.
FBACKAL (P15)
Indicates whether the feedback alarm for this axis will be ON or OFF.
AXISCHG (P16)
Indicates the counting direction. If correct, leave it as is, but to change it, select YES if it was set
to NO and viceversa. If this parameter is changed, s.m.p. LOOPCHG (P26) must also be changed
so the spindle does not "run away".
DWELL (P17)
Indicates the dwell from the moment the "ENABLE" signal is activated until the velocity command
is sent out.
ACCTIME (P18)
This parameter is used when working with the spindle in closed loop and it indicates the acceleration
time given to reach the maximum speed set by s.m.p. MAXVOLT1 (P37) thru MAXVOLT4 (P40) in
each gear. This time is also valid for the deceleration stage.
When using a CAN servo system, if parameter NPULSES and parameters INPREV
and OUTPREV of all the gears are set with a ·0· value, the CNC will assume the
equivalent ones of the drive.
Value Meaning
NO It does NOT use differential signals.
YES It uses differential signals.
Default value: YES
Value Meaning
OFF No feedback alarm desired, it is canceled.
ON Feedback alarm is being used.
Default value: ON
Possible values
NO / YES.
Default value: NO
Possible values
Integers between 0 and 65535 ms.
Default value: 0 (there is no dwell).
Possible values
Integers between 0 and 65535 ms.
