3.10.5 Examples of Multichip Interpolation
Examples using 2 chips: main and sub chips are as follows.
■
Example 1 Multichip Interpolation with each chip of 2-axis X and Y
【
Program Example
】
// Interpolation mode setting of main and sub chips
// Writing to main chip
WR6
← 0403h Write // Main chip Designation of X,Y Interpolation axis
WR0 ← 002Ah Write
// Writing to sub chip1
WR6
← 0803h Write // Sub chip Designation of X,Y Interpolation axis
WR0 ← 002Ah Write
// Writing to sub chip2
WR6
← 0803h Write // Sub chip Designation of X,Y Interpolation axis
WR0 ← 002Ah Write
//Driving parameters setting to main axis of main chip (2M PPS constant speed driving)
WR6 ← 1200h Write // Initial speed 8M PPS (maximum in specification)
WR7 ← 007Ah Write
WR0 ← 0104h Write
WR6
← 8480h Write // Drive speed 2M PPS
WR7 ← 001Eh Write
WR0 ← 0105h Write
// Writing of finish point data and Receiving error check
// Writing to main chip
WR6 ← 0014h Write // Finish point1 X 20
WR7 ← 0000h Write
WR0 ← 0106h Write
// Receiving error check of sub chip1 Handling A
RR0 ／ D4,D5 Read
If D4,D5=1, jump to ERROR(sub chip) // Go to error handling
// Receiving error check of sub chip2 Handling B
RR0 ／ D4,D5 Read
If D4,D5=1, jump to ERROR(sub chip) // Go to error handling
WR6 ← 000Ah Write // Finish point1 Y 10
WR7 ← 0000h Write
WR0 ← 0206h Write
// Execute the handling A
// Execute the handling B
// Writing to sub chip1
WR6 ← FFF6h Write // Finish point1 X -10
WR7 ← FFFFh Write
WR0 ← 0106h Write
// Receiving error check of main chip Handling C
RR0 ／ D4,D5 Read

// Execute the handling B
WR6
← 0005h Write // Finish point1 Y 5
WR7 ← 0000h Write
WR0 ← 0206h Write
// Execute the handling C
// Execute the handling B
// Writing to sub chip2
WR6 ← 0019h Write // Finish point1 X 25
WR7 ← 0000h Write
WR0 ← 0106h Write
// Execute the handling C
// Execute the handling A
WR6
← FFF4hWrite // Finish point1 Y -12
