Formatting and Interpreting Data Blocks
Chapter 7
7Ć75
The status block indicates a programming error if you issue the
return-to-position command with the servo positioning assembly in auto
mode.
Bit 13 Software Travel Limits Override
Turn on bit 13 to override software travel limits. With the servo
positioning assembly in the auto or manual mode, and this bit on, software
axis travel limits in the parameter block have no effect on axis motion.
This allows axis motion to continue beyond the travel limits.
CAUTION: If values for software travel limits are zero, there
are no software travel limits. To guard against damage to
equipment, exercise caution when operating an axis without
software travel limits.
Bit 14 Jog Rate Select
Bit 14 determines the jog rate for jogs, the search home operation, and the
return-to-position operation.
Turn off this bit to select the low jog rate.
Turn on this bit to select the high jog rate.
You enter the high and low jog rates in the parameter block.
If this bit changes state during a jog operation, the axis accelerates or
decelerates to the newly commanded rate at the global accel/decel rate
programmed in the parameter block and continues jogging at the newly
commanded jog rate.
During a search home or return-to-position operation, the axis ignores
changes in this bit.
Bit 16 Tachometer Calibrate
Turn on bit 16 for the tachometer calibration procedure described in
chapter 9. At all other times, leave it off.
