3.14 EC-## Feedback Option
3.14.1 EC-1# Inc. Enc. Interface
EC-10 Signal Type
Select the incremental type (A/B channel) of the encoder in use.
Find the information on the encoder data sheet.
Select
[0] None
if the feedback sensor is an absolute encoder
only.

Sinusoidal 1Vpp
EC-11 Resolution (PPR)
Range:
Function:
1024
*
[10 - 10000] Enter the resolution of the incremental
track, i.e. the number of pulses or periods
per revolution.
3.14.2 EC-2# Abs. Enc. Interface
EC-20 Protocol Selection
Option:
Function:
NOTE
This parameter cannot be adjusted while
the motor is running.
Select
[1] HIPERFACE
if the encoder is absolute
only.
Select
[0] None
if the feedback sensor is an
incremental encoder only.

SSI
EC-21 Resolution (Positions/Rev)
Range:
Function:
8192
*
[4 - 131072] Select the resolution of the absolute
encoder, i.e. the number of counts per
revolution.
The value depends on setting in
EC-24 SSI Data Length
Range:
Function:
13
*
[13 - 25] Set the number of bits for the SSI telegram.
Choose 13 bits for single-turn encoders and 25
bits for multi-turn encoder.
EC-25 Clock Rate
Range:
Function:
260 kHz
*
[100 - 260
kHz]
Set the SSI clock rate. With long
encoder cables the clock rate must
be reduced.
EC-26 SSI Data Format
Option:
Function:
[0]
*
Gray code
[1]
Binary code Set the data format of the SSI data. Choose
between Gray or Binary format.
EC-34 HIPERFACE Baudrate
Option:
Function:
NOTE
This parameter cannot be adjusted while the
motor is running.
Select the baud rate of the attached encoder.
The parameter is only accessible when
is set to
[1] HIPERFACE

EC-61 Feedback Signal Monitoring
Select which reaction the frequency converter should take in
case a faulty encoder signal is detected.
The encoder function in
EC-61 Feedback Signal Monitoring
is an
electrical check of the hardware circuit in the encoder system.
