Resetting El and Az Encoders

Take the telescope to elevation 3 and azimuth 177 using the elslewtohold and azslewtohold commands on the MCSPU.

Then go to the encoders page typing enc

Type the following commands to start the reset:

azenreset 177 2

elencreset 3 2

If the telescope has lost its position, you will have to load new values to the encoders.

To do this, switch to velocity mode by typing first


The load the new values by typing

elload degrees


azload degrees

be careful to be in vel mode and NOT in pos mode before loading values to the encoders.

Then type,

elencreset 3 2

This time you should expect the reset process to succeed.

If some of encoders are disabled, like for example

M0 r : 120:00:00 Dis/unk

you will need to enable it by typing,

elenceable 0

In this case encoder 0 is being enabled. If the commands succeeds, the same line will look like this,

M0 r : 120:00:00 En/Fset
