6.5 Feedback

When the CDHD2S drive system contains an electronic motor nameplate, the specific feedback
parameters will be directly transmitted to the drive after power-on, and it is impossible to operate.
When a motor is selected from the ServoStudio2 motor library, the motor feedback parameters
are preset and written to the drive. These parameters are defined by the manufacturer and cannot
be modified by the user; if you want to modify these parameters, please contact technical support.
FEEDBACKTYPE defines the motor feedback type used in the drive application.
CDHD2S supports a variety of motor feedback devices, including:
BiSS-C encoder
⚫
EnDat encoder
⚫
HIPERFACE encoder
⚫
Incremental A-quadrature-B encoder, available,without Hall sensor (or reversal
⚫
tracking)
Nikon encoder
⚫
Resolver
⚫
sensAR encoder
⚫
Sine encoder
⚫
Tamagawa encoder

6.5.1 Incremental encoder

Type and resolution
CDHD2S supports multiple types of incremental encoders.
The following parameters are used to configure and monitor the incremental encoder.
VarCom
MENCTYPE
MENCRES
CDHD2S monitors all encoder signal lines. If any wire is damaged, an A/B disconnection fault
will be generated (digital display: r4|Fr4)
Hall signal
The CDHD2S supports single-ended (or open collector) and differential Hall signals.
