4.1.5 Miscellaneous Commands
The following commands are available to operate on a group of axes
simultaneously:
•
HO and HF: These commands are used to turn ON and turn OFF
the power to all axes in a group respectively. The axes assigned to
a group can be powered ON or OFF individually using
MO and
MF commands also. A group is considered to be ON if all axes
assigned to that group are ON.
•
HP: This command is used to read the actual position of all axes
in a group.
•
HS: This command is used to stop the group motion.
•
HW: This command is used to wait for the group motion to stop
and a user settable delay period thereafter.
•
HX: This command is used to delete a group.
•
HZ: This command is used to read the size or the number of axes
assigned to group.
4.2 Slaving a Stage to Trackball, Joystick, or a Different Stage
4.2.1 Introduction – Slaving a Stage
ESP series of motion controllers allow three different ways in which a
slave axis can respond to a master axis. They are:
1. Slave to master's desired position (trajectory).
2. Slave to master's actual position (feedback).
3. Slave to master's actual velocity for jogging.
