Technical Data
Input resistance: 120 Ohm
Process data channel: 1Vpp
Parameter channel: EIA RS485 half duplex
Clock signal output: EIA RS485
Maximum input frequency: 200 kHz
Encoder line number: 1...2048 inc
Maximum cable length: 100 m
(based on signal levels, otherwise see below)
Cable length based on cable resistance
The maximum cable length is calculated as follows:
Length =
V - Vmin
=
5.25V - 4.75V
= 83.3 m
Imax * R 0.2A * 0.003 Ω/m
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 single turn; ECI 1317 Singleturn
• HeidenhainROQ 425 Multiturn; EQI 1329 Multiturn
However, this does not restrict the use of rotary encoder with same
speci 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
communication to the encoder has stopped, it will trigger the error
E.ENCC.
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 E.ENCC and lock out operation by changing LF.3
to con guration mode. No further operation is possible.
If the encoder was exchanged the drive will auto reset the E.ENCC
fault but will remain in con guration mode because the user will need
to learn the new encoder position before operation can continue. See
section 5.11.1
If there is an encoder triggered fault or problems with the encoder cable
the E.ENCC error will not clear and the problems must be diagnosed
through parameter LF.26. To clear the E.ENCC error, it is necessary to
go to parameter 0.LF.26, press "Func" and then press "Enter".
