B--65245EN/02
HANDLING
56
CAUTION
1 The purpose of this data, when used by the host, is limited
to display on the host. This data consists of 32 bits of DI
signals; the bits are not updated at a time, but are updated
on a bit -- by-- bit basis. So, if this data is being updated when
coordinates are read during movement on axes, the correct
position may not be read normally. This data is prepared for
position display on the host, so that this data cannot be used
to make a machine area check. However, correct
coordinates can be read even during movement on axes by
establishing synchronization between the host and servo
amplifier unit. For details, see Section 3.8.
2 The current position number (point turret cartridge number)
is output upon completion of positioning in reference
position return operation, point positioning, or ATC
operation of peripheral equipment control. If a move
command such as for jog feed is then executed, the
matching between the current position number and current
position on the axes is lost. So, after a move command such
as for jog feed is executed upon completion of reference
position return operation, point positioning, or ATC
operation, the current position on the axes cannot be
controlled by viewing the output of the current position
number on the host. Moreover, the matching between the
current position number and current position on the axes is
lost if a command executed for ATC operation indexing is
stopped for a cause such as a reset or alarm.
(6) R esponse data check signals DSP1 and DS P2
[Classification]
Input signal <Xx+2#4 to #5>
[Function]
The servo amplifier unit indicates the contents of the response data.
[Input condition]
The servo amplifier unit specifies the response data using a
combination of signals, as listed below.
DSP2 DSP1 Response data
1 1 Coordinate or motor current value
1 0 Current position number (ATC, point number)
NOTE
The setting of parameter No. 20 is used for distinction
between a coordinate and motor current value.
(7) Response data write completion signal ABSWT
[Classification]
Input signal <Xx+1#0>
[Function]
After writing response data (Xx+3 to Xx+6), the servo amplifier unit
inverts this signal for notification to the host.
