Position encoder
signal
Incremental position encoders with 1 V
PP
signals and absolute encoders with
EnDat interface can be connected to the CC 61xx.
Define the type of signal, input frequency and terminating resistance in the
following machine parameters.
MP_posEncoderSignal: 1 V
PP
signal. On encoders with EnDat interface
you set the signal type 1 V
PP
.
MP_posEncoderFreq: Maximum input frequency
MP_posEncoderResistor: Terminating resistor
MP_posEncoderSignal
Signal amplitude at position encoder input
Available from NCK software version: 597 110-01.
Format: Selection menu
Selection: 1Vpp
Input signal of the encoder is 1 V
PP
11 uA
Input signal of encoder is 11 µA
PP
Default: 1 Vpp
Access: LEVEL3
Reaction: RUN
MP_posEncoderFreq
Input frequency of position encoder inputs
Available from NCK software version: 597 110-01.
Format: Selection menu
Selection: fast
Input frequency is
At 11 V
PP
: 350 kHz
At 11 µA
PP
: 150 kHz
slow
Input frequency is 33 kHz
Default: fast
Access: LEVEL3
Reaction: RUN
With MP_posEncoderResistor you define whether a terminating resistor is
required. (120 ohms)
This parameter may be required if the encoder signals are looped through a
drive motor, or if Y cables are used. It is usually sufficient to set the parameter
to without.
The CC 61xx does not support encoders with 11 µA
PP
signal!
