5-2 Parameter Description
PRM18: Robot type number
This parameter shows the robot number currently used. (See "15-1-2 Robot number list".)
This is a read-only parameter. When changing the robot number or if the memory contents
are corrupted, perform parameter initialization. (See "10-1 Initialization".)
* When the robot setting is made for a Multi-Flip, this parameter value is set to 0 and the
robot type number for each axis is shown by PRM72 and PRM112.
PRM19: Controller version 1
This parameter reads out the version information (1) on the control software in the con-
troller.
This is a read-only parameter.
PRM20: System mode selection
This parameter specifies the system operation mode. When you want to use the DRCX
controller in operating specifications that differ from normal mode, for example, to make
it compatible with the conventional controllers, change this parameter as explained below.
This parameter functions are allocated in bit units.

Bit 0: General-purpose input definition for using an I/O point movement
command
This selects a general-purpose input used for an I/O point movement command
(ABS-PT, INC-PT).
In normal mode, use DI0 to DI9 to specify the point number and DI10 to DI11 to
select the speed. All points (P0 to P999) can be specified with a movement com-
mand.
In conventional model compatible mode, use DI0 to DI7 to specify the point number,
and DI8 to DI9 to select the speed. Points P0 to P254 can be specified with a
movement command but points P255 to P999 cannot be selected.
