Part 3 Positioner Mode
2. Parameters
The following parameters must be set in the product switching mode.
Table: Parameter Settings in Product Switching Mode
Type No. Parameter Function
25 Operation mode type 2: Product switching mode
71 Positioner mode parameter 1
Position-number input mode specification (0: Binary,
 0: BCD)
* Default value: 0 (Binary)
72 Positioner mode parameter 2
Number of position-number input bits
Binary: Number of bits – 1 through 15 bits
BCD: Number of BCD digits – 1 through 3 digits Other
73 Positioner mode parameter 3 Number of positions per product
When the above parameters are set, the actual position movement commands will apply based on the
following formula:
“(Product number input – 1) x Number of positions per product + Position number input”
For example, assume that the parameters are set as follows:
Other parameter No. 71 = 0 (Binary) “Position-number input mode specification”
Other parameter No. 72 = 6 “Number of position-number input bits”
Other parameter No. 73 = 50 “Number of positions per product”
Each position number is assigned to six bits of inputs 1 through 6 (007 through 012), as a binary code,
and position Nos. 1 through 63 can be specified.
Each product number is assigned to 10 bits of inputs 7 through 6 (013 through 022), as a binary code, and
30 types can be specified (the number of types is limited to 30, because the maximum number of position
data is 1500). If any greater value is set that brings the number of position data to more than 1500, a
“point number error” will generate.
* If the value of position number input exceeds the number of positions per product, the controller will
recognize that “1” has been set as the position number.
(Note) The result of “Number of position-number input bits” + “Number of product-number input bits” must
not exceed 16 (bits).
