11.1 error register
The error register is a 16bit register. Each bit describes different error. Once error has occurred the
error register changes and error message as a decimal number will be issued via interface.
„
?ERR,channel,error
“ CR LF.
The decimal sum of all bits results the error value:

For high precision positioning with nm-resolution, you must warm up the amplifier 2 hours before
use. A constant temperature is beneficial. Consider that a variation of 5 Kelvin results in an
elongation of 13
μm in steel with a length of 200 mm. The best results for resolution and accuracy
can only be achieved by setting the digital target values. Therefore, please switch off the analog
modulation input when it’s not being used.
Equipment customization makes adaptations, according customer preferences, that are possible in
terms of the technical threshold values e.g. the main voltage or the output voltage. Please contact
our technical service department in order to find out the possibilities for your specific application.
Special adaptations must be paid for by the customer.
