Includes regisitration functionallity(Registration is available only using the
encoder's 1 Volt index pulse.)
8903-M1-00 Sin/Cos Registration (fitted in the OPTION A position)
When installed; the part number changes as follows:-
Part No: 890XX-XXXXXXXX-XXXXXX7X (replaces E1 option 1) see note *
Legacy Part No: 890XX/X/XXXXX/X/XX/X/XX/XX/XX/XX/M1/XX (replaces E1)see note *
8903-M1-00-FF Indicated factory fitted
Interpolates each encoder line with 11-bit accuracy
giving 4 million counts per revolution on a 2048
line encoder
• Optional 1V input from ‘Z’ index pulse for use
with registration
• Captures encoder position on arrival of every edge
using up to two registration mark inputs
• Decoding logic to interface the encoder to the
drive’s microprocessor
• Supplies 5V or 10V to the encoder
• Decodes Heidenhain Endat 2.1 absolute position
Encoders
The 8903/M1 functions as speed feedback for the drive.
Auxiliary Digital Inputs and the encoder’s index pulse (if supplied by the encoder) are available
for registration event inputs.
The Auxiliary Digital Inputs are also available for general purpose digital inputs.
Auxiliary Digital Outputs are available for a simulated pulse encoder output, or for general
purpose digital outputs.
In this combination, a reference encoder position would normally be supplied via a Firewire
option interface (8903/FA).
