7.2 Feedback 1
The Feedback view allows you to configure the primary position feedback device fitted to your motor.
When you select your feedback device from the Feedback Selection list, the appropriate feedback con-
figuration choices appear below the dial.
7.2.1 Overview
The AKD PDMM offers a variety of feedback solutions, which allow you to optimize your system based
on your specific machine needs. The available feedback options include resolver, SFD, sine-cosine
encoder (Endat 2.1, BiSS, Hiperface), incremental encoder, as well as line-count, single, and absolute var-
iations. Your motor model number will indicate the type of feedback that you have. With some incremental
encoders, parameters are set up in the encoder itself, and the AKD PDMM drive recognizes the feedback
automatically and sets up the drive accordingly. This automatic recognition is called "plug and play". Cur-
rently, SFD and Endat are plug and play encoders. Other feedback types require that you enter param-
eters manually.
The following table lists current support for primary and secondary feedback:
Primary Secondary
Resolver Std & Multi pole Yes No
SFD Yes No
Incremental (Digital)
Encoder With Halls and Index Yes No
No Halls with Index Yes Yes
No Halls with No Index Yes Yes
Analog Sin/Cos Encoder With Digital Halls Yes No
With Digital Halls and Analog Index No No
No Halls and No Index Yes No
EnDAT 2.1 Single & Multi Turn Yes No
EnDAT 2.2 All Digital Yes Yes
Analog / Digital Yes No
BiSS All Digital (Mode C) Yes No
Analog / Digital Yes No
Hiperface Analog / Digital; Single & Multi Turn Yes No
All Digital No No
7.2.2 Using Feedback Options
Use the Feedback screen to set up your system to match the proper feedback device. By default, the
drive uses the Auto setting to detect feedback devices. This setting allows the drive to test the feedback
device to see if it is a recognized plug and play device. If the drive recognizes the device, then all the
parameters for that device and motor are loaded into the drive. Both the feedback and the motor infor-
mation are now present in the drive and the system is operable.
If the feedback is a non- plug and play device, then you can choose from the list of supported devices in
Feedback Selection list and then enter the line count manually. The following sections describe each sup-
ported device available in the Feedback Selection list and the input information required to configure
each device.
7.2.2.1 Auto
This is the default setting and is used to determine if a plug and play device is available. If a plug and play
device is available, the
Auto mode is replaced by the feedback device detected, along with the appro-
priate resolution settings.
