$PR[x] : Position Registers. While modified via code, their structural properties reside in system memory. 3. Error Handling and System State
: Auto-assignment of UOP ( $IO_AUTO_UOP ) and override signals in AUTO mode ( $AUTOMODE_OV ). 2. How to Access Variables on the Controller
$FINE_DIST : Sets the fixed distance (in mm) the robot moves when jogging at "FINE" speed.
$MASTER_COUNTR : Stores the encoder pulse counts at the mastered position. This is critical for recovering from a dead battery loss of master. fanuc robot system variables pdf
Maintain critical system integrity (e.g., hardware models or real-time axis positions) and cannot be modified by the user.
Some variables require a controller restart (Cold Start or Controlled Start) to take effect, while others apply instantly.
Before you start editing variables, follow these golden rules to keep your system safe: $PR[x] : Position Registers
System variables are a crucial part of the FANUC robot control system, which stores and manages data related to the robot's status, position, velocity, and other parameters. These variables are used to control and monitor the robot's movements, perform calculations, and interact with external devices. System variables are categorized into several types, each with its own specific function and application.
: Controls the jog speed percentage. 2. Robot Status and Alarms (
| Access Type | Meaning | Description | |-------------|---------|-------------| | | Read only | Values are set automatically by the system and cannot be modified by users | | RW (Read/Write) | Read and write | Users can view and modify these values to customize system behavior | | FP (Field Protection) | Field protection | Applies access restrictions to individual fields within a structure | | NO (No Access) | No access | Cannot be accessed under normal operating conditions | Error Handling and System State : Auto-assignment of
Dictates the global override speed of the robot immediately upon controller boot.
