Counting Input (Option)

14.1

Function

For the JetMove 225-480, an optional integrated counter card can be ordered (article 
designation of the device: JM-225-480...-CNT). It supplies a counting input equipped 
with the following interface:
• EnDat 2.2 by Heidenhain
• Synchronous Serial Interface (SSI)
• Incremental counter

The received or counted value of an actual position can be read via a JetMove 
register by the controller program or processed by the firmware of the JetMove in the 
controllers.
