+ | ===== Installation ===== | ||
+ | |||
+ | The linear encoders are installed at the factory on your stage. | ||
+ | |||
+ | The encoder read heads and scales are embedded within the three stage plates. | ||
+ | |||
+ | <WRAP center round important 60%> | ||
+ | ===== Warnings ===== | ||
+ | |||
+ | * DO NOT remove the encoder heads or the encoder scales from the stage unless you intend to do a complete realignment of the linear encoder. | ||
+ | * DO NOT make adjustments to the trim potentiometers on the encoder electronic modules. | ||
+ | * Please contact ASI if you believe that the linear encoder is not functioning properly. | ||
+ | * Install the stage on your microscope as described previously in this manual. | ||
+ | </ | ||
+ | |||
+ | |||
+ | Connect the encoder read-heads to the correct connectors on the back of the MS2000, RM2000 and Tiger controller. | ||
+ | |||
+ | ===== Switch Settings ===== | ||
+ | |||
+ | **DIP SWITCH #3:** This switch informs the firmware which encoder is in use. DIP Switch 3 should be DOWN for the linear encoders, UP to use the rotary encoders on the motors. | ||
+ | The controller must be reset after changing DIP switch #3 for the firmware to notice the change. | ||
+ | |||
+ | <WRAP center round info 60%> | ||
+ | Note: There are no Dip-Switchs in Tiger system , Axis is set in LE mode with [[commands: | ||
+ | </ | ||
+ | |||
+ | |||
+ | ===== Maintenance ===== | ||
+ | |||
+ | The linear encoders are holographic devices that view an extended region of the scale at all times. | ||
+ | |||
+ | ===== Firmware Configuration and Features ===== | ||
+ | |||
+ | The correct firmware configuration is installed at the factory. | ||
+ | |||
+ | <wrap cmd> CCA X=21 </ | ||
+ | <wrap cmd> RESET </ | ||
+ | 10nm for Heidenhain and Renishaw encoders | ||
+ | |||
+ | <wrap cmd> CCA X=52 </ | ||
+ | <wrap cmd> RESET </ | ||
+ | 2.5nm for MicroE encoders | ||
+ | |||
+ | The index on the Linear encoders can be used as an absolute position reference. | ||
+ | |||
+ | ===== MicroE In-Field Alignment and Adjustment ===== | ||
+ | |||

+ | |||
+ | |||
+ | If you wish to align the linear encoders to increase or decrease its resolution, it can be done thru the alignment too shown in figure a (purchased separately). The alignment tool will not only allow you to align the encoder but also to change the encoder resolution between 5um to 1.22nm and, adjust the programmable low pass filter which may reduce the maximum speed but improves noise and stability. | ||
