2. PR Parameters:
PR parameter data type is 16-bit data, one parameter occupies one register (one 16-bit register = 2 8-bit bytes).
Parameter NO.

Description
Pr8.00
0x6000
PR global control function
Bit0: CTRG effective edge. 0--rising edge, 1--double edges
Bit1: Soft limit..
0--disable, 1--enable
Bit2: Homing after power on. 0--no, 1--yes
Bit4: CTRG trigger type. 0--refer to bit0, 1--level trigger
Pr8.02
0x6002
PR control register
(1) Write commands to 0x6002 to select and trigger each action:
Write 0x1P (“P” = 0-15 ), run the path P motion;
Write 0x20, homing;
Write 0x21, manually set to zero position;
Write 0x40, quick stop;
(2) Read 0x6002 can check the running path NO. and status:
Return “0x000P”, path P motion complete, can receive new motion command;
Return “0x001P or 0020 or 0040”, not yet responding to commands;
Return 0x010P, path P motion is running;
Return 0x0200, command completed and waiting for positioning;
Return 0x020P, a position following error during path P;

Homing mode
Bit0: homing direction, 0--CW, 1--CCW;
Bit1: Whether to move to the specified position after homing, 0--no, 1--yes;
Bit2: homing method, 0--limit switch homing, 1--home switch homing,
Note:
(1) Write 0x21 to 0x6002, manually set the current point to zero position)
(2) Other methods are not valid
