Position Memory; Mechanical Handle; Spindle Control - YASKAWA MOTIONPACK-110 Descriptive Information

3.9 POSITION MEMORY
The current value display (only axis position) on previous turning OFF of the power can
be retained in the offset area even after the power is turned OFF. Normally, the position
memory should be executed at the machine stop. To effect this function, set the system
parameter #1003 D1 to "1."
When the position memory signal (PMEM) is turned ON, current display axis
positions X, Y and Z are retained in the offset numbers H87, H88 and H89, respectively.

3.10 MECHANICAL HANDLE
When the servo subsystem power is off and the machine is moved with the mechanical
handle, the current value position display follows it.
However, generally when the servo subsystem power is off, alarm (No.51 SERVO
POWER NOT SUPPLY) occurs, thus the function should be used by turning On the alarm
clear signal (ACR) to prevent the alarm from occurring.

3.11 SPINDLE CONTROL FUNCTION
Simple spindle control can be performed by using axis module D/A output. Operation for
the spindle is performed by setting the axis module axis setup number to 4. See Par. 10.3.
For the feedrate command, the rotation speed of the spindle (rpm) is programmed
in a numeric value of five digits following code S.
