Data item
ALM2 The ALM 2 bit turns ON and the
ALM 2 indicator on the Data Set-
ting Console lights when any of
the following errors occur.
Memory error
Bank change error
Communications error
Data transfer error
Power failure error
Parameter error
ALM1 The ALM 1 bit turns ON if an error
occurs due to the resolver being
disconnected. At that time, the
ALM 1 indicator on the Data Set-
ting Console lights.
Not used. Set to "0."
Memory load When this flag is ON, memory downloading and uploading is possible.
enabled This flag is ON when the Data Setting Console display is lit, and OFF
when the display is blinking. (The display blinks while data is being
set.)
Origin adjustment Turns ON when origin adjustment is completed, based on the Origin
completed Adjustment Flag (bit 01 of word n) or the EEPROM Write Flag (bit 02
of word n) turning ON, and turns OFF based on these bits turning OFF.
Memory load Turns ON when memory downloading (bit 05 of word n) or memory
completed uploading (bit 04 of word n) is completed, and OFF based on either of
these bits turning OFF.
Resolver stopped ON while resolver rotation is stopped (4 r/min or less), and OFF during
(see note 2) rotation.
Error Normally OFF. Turns ON when a Cam Positioner Unit error occurs. At
that time, the ALM indicator on the front panel of the Cam Positioner
Unit lights.
RUN mode ON when the operation mode selector on the front panel of the Cam
Positioner Unit is set to RUN, and OFF when the selector is set to
PRG.
In operation ON during operation (i.e., when the Operation Flag, bit 00 of word n, is
ON).
Not used. Set to "0."
When errors occur, the following codes are output. (2-digit BCD)
01: Memory error
02: Communications error
03: Power failure error
20: Bank change error
21: Data transfer error
22: Parameter error
10: Resolver disconnection error
For details, refer to the SECTION 5 Troubleshooting.
1. Data other than 0 may be output even if the Resolver is not operating when
the power is turned ON, the Special I/O Unit has been reset, or origin ad-
justment has been executed.
2. May turn OFF even if the Resolver is not operating when the power is
turned ON, the Special I/O Unit has been reset, origin adjustment has
been executed, or the Resolver has been disconnected.
Data contents
When the errors on the left occur,
the following conditions occur
simultaneously.
The ALM indicator lights on the
front panel of the Cam Posi-
tioner Unit.
Bit 02 of word n + 8 turns ON.
The error code is output to word
n + 9.
