1. Select instruction
This item selects which ABS instruction to use ("ABS1", "ABS2", "ABS3", or "ABS4").
The absolute position counter to be initialized differs with the instruction.
The initialized status of D8240 to D8247 can be checked with the absolute position counter initialized flags defined in D8239
(absolute position control status).
When the FC6A Series MICROSmart switches from stop to run, 0 (not initialized) is stored in the absolute position counter
initialized flags. Then when the absolute position counters are initialized using the ABS instruction, 1 (initialized) is stored.

*1 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see "32-bit Data Storage" on
*2 The values of the absolute position counters are retained by the backup battery even when the power is turned off. When a keep data error
occurs, the values are initialized to 0.
*3 The special data registers are read only. To change the values of D8240 to D8247, use the ABS instruction.
*4 When the RAMP, ARAMP, ZRN, and JOG instructions are used with Reversible control disabled, the absolute position counters are not
updated.
*5 When specify absolute position mode is enabled in the RAMP instruction, the target position is specified as the absolute position. When using
specify absolute position mode in the RAMP instruction, initialize the corresponding absolute position counter in advance with the ABS
instruction. For details, see "RAMP (Trapezoidal Control)" on page 18-15.
