Technical Data
• Input resistance:
• Process data channel: 1Vpp
• Parameter channel:
• Clock signal output:
• Maximum input frequency:
• Encoder line number: 1...2048 inc
• Maximum cable length: 100 m
Cable length based on cable resistance
The maximum cable length is calculated as follows:
Length = V - Vmin = 5.25V - 4.75V
Imax * R
where
Imax = supply current of encoder [amps]
V = voltage supply of the drive = 5.25V
Vmin = minimum supply voltage of the encoder
R = cable resistance (0.07 Ω/m) for Standard KEB cables
(0.03 Ω/m) for type "L" KEB cables
The following ENDAT encoders have been tested for use:
Heidenhain ECN 1313, 413, 113 single turn

However, this does not restrict the use of rotary encoder with same specifi-
cations of other manufacturers
The recognition of encoder loss or exchange is a software function and
dependent on the encoder type. If the drive senses that the serial communi-
cation to the encoder has stopped, it will trigger the 'Error Encoder Interface'
fault.
If the encoder is replaced or disconnected, the drive will trigger an error
or warning that the encoder was changed. The drive will display the error
message 'Error Encoder Interface'.
If the encoder was exchanged the drive will auto reset the 'Error Encoder
Interface' fault. The user will need to learn the new encoder position
before operation can continue. See section 5.10.
If there is an encoder triggered fault or problems with the encoder cable
the 'Error Encoder Interface' fault will not clear and the problems must be
diagnosed through parameter LE12. To clear the 'Error Encoder Interface'
fault, it is necessary to go to parameter LE01, press "Enter" and then
press "Enter" again to confirm.
