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.
Option: Function:
[0] None
[1] * RS422 (5V TTL)
[2] 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.
[0] * None
[1] HIPERFACE
[2] EnDat
[4] 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-20 Protocol Selection.
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
EC-20 Protocol Selection is set to [1] HIPERFACE.
[0] 600
[1] 1200
[2] 2400
[3] 4800
[4] * 9600
[5] 19200
[6] 38400
3.14.3 EC-6# Monitoring and App.
EC-60 Feedback Direction
Option: Function:
NOTE
This parameter cannot be adjusted
while the motor is running.
Change the detected encoder rotation
direction without changing the wiring to
the encoder.
[0] * Clockwise
[1] Counter
clockwise
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.
Option: Function:
[0] Disabled
[1] * Warning
[2] Trip
