BELT.MODE system parameter BELT.MODE system parameter Syntax ...BELT.MODE Function Set characteristics of the conveyor tracking feature of the eV+ system. Usage Considerations This option is available only if your system is equipped with the eV+ Extensions option. The current value of the BELT.MODE parameter can be determined with the PARAMETER monitor command or real-valued function. The value of the BELT.MODE parameter can be modified only with the PARAMETER monitor command or program instruction. Details This parameter is interpreted as a bit-flag word. The initial setting of this parameter is 0. That is, all the bits are zero.
Bits can be set by assigning the value resulting from adding together the desired bit mask values (see the example below). The bit flags have the following interpretations: Bit 1 (LSB) Upstream/downstream definition (mask value = 1) When this bit is set to one, the instantaneous direction of travel of the belt is used to define upstream and downstream for the window testing routines (both in the internal motion planner and the WINDOW real-valued function). When this bit is set to zero, going from upstream to downstream always corresponds to traveling in the direction of the positive X axis of the nominal transformation.
Bit 2 Stopped-belt processing (mask value = 2) When this bit is set to one, a program error will be generated during motion planning if the destination is outside of the belt window and the belt is stopped. When this bit is set to zero, if the belt is stopped during motion planning, the direction of the positive X axis of the nominal transformation is used to define the downstream direction. The normal window-error criteria are then applied (see below). eV+Language Reference Guide, v2.x, 18319-000 Rev A Page 89
