Hi-Resolution (Stegmann) Feedback Option Card Specifications
Supported Encoders
Table C.A specifies which encoders are supported by the 700S
Hi-Resolution Stegmann Encoder Feedback Option module.
Important:Please note that encoders must be ordered as "Single Ended".
This will ensure that the RS-485 channel has the proper
termination network installed at the factory.
Table C.A Supported Stegmann Encoders
Consideration Description
Encoder Voltage Supply 11.5V dc @ 130 mA
Stegmann Feedback Sine/Cosine 1V P-P Offset 2.5
Maximum Cable Length 90m (295 ft)
Maximum Frequency
(Encoder Speed)
12.5 μs/cycle
(4687.5 RPM for encoders with 1024 sine cycles per revolution)

RS-485 Interface The Hi-Resolution Feedback Option card obtains the following
information via the Hiperface RS-485 interface shortly after
power-up:
• Address
• Command Number
• Mode
• Number of turns
• Number of Sine/Cos cycles
• Checksum
