Combined Tacho and Encoder Feedback
ENCODER/ANALOG
If an analog tachogenerator and digital encoder are to be used, the Encoder Option Board
receives the digital signal, the analog signal is routed to Terminals B2 (Tacho) and B1 (0V).
Note: External scaling resistors are required for the Analog Tacho Feedback and a shorting
link inserted in the analog plug to directly connect terminal B2 to the analog speed feedback
input.
Please refer to Parker SSD Drives Engineering Department for assistance with this feature
