2.5.2. Changing Collet Chucks (ACS150)

ACS series stages are configurable with ER collet chucks for both ER25 and ER40 collets. In order to
switch from the ER25 to the ER40 (or vice versa), some disassembly is required.
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
Step 1: Remove power to the stage before installing or removing the collet.
Step 2: Apply air pressure to loosen the collet chuck.
Step 3: Remove the collet nut by turning it counterclockwise. If necessary, use a spanner wrench (available
from Aerotech). Use caution when removing the collet nut as the collet may fall from its housing and
be damaged.
D A N G E R : The collet cover is under tension from internal springs. Removing the collet cover
screws incorrectly can result in personal harm and damage to the equipment.
Step 4: Remove air pressure from the stage. This will decrease the tension of the internal springs and make
disassembling easier. Only continue to disassemble if the air pressure is completely removed.
