5. DRIVING MOTOR
The current software limit setting can be written using the function code "10h" (Preset Multiple
Registers).
At this time, set "02h" for Number of entries.
Set the stroke limit value in the reverse direction in Min Position Limit (stroke limit -) in units of
commands.
Set the stroke limit value in the forward direction in Max Position Limit (stroke limit +) in units of
commands.
If Min Position Limit (stroke limit -) and Max Position Limit (stroke limit +) are set to the same value, the
software limit function is disabled.
(3) Program number specification (Target Program No.: 2D70h)
Address
2D70h Target Program No.
The currently specified program number can be read using the function code "03h" (Read Holding
Registers).
A program number can be set using the function code "10h" (Preset Multiple Registers).
(4) Control status (Statusword: 6041h)
Address
6041h Statusword
The current program operation status can be read using the function code "03h" (Read Holding
Registers).
The bits of this register that relate to the program operation are shown below.
(a) Bit 10 of the control status (6041h) (Target reached)
Bit 10 turns on (0) when the start signal turns on. Bit 10 turns on (1) when the command position is
reached. If bit 8 (Halt) of the control command is set to "1", bit 10 turns on (1) when a deceleration
stop is completed.
(b) Bit 12 (Program Running) of the control status (6041h)
During a program operation, bit 12 is on (1). When the program stops running or has ended, the bit
