6 Encoder/feedback system
The 8400 TopLine uses various encoder/feedback systems for the motor controls with speed
feedback and the position control:
• Resolver at X7
• Multi-Encoder at X8
• Incremental TTL encoders
• Incremental SinCos encoders
• SinCos absolute value encoder with HIPERFACE® protocol
• SSI absolute value encoder with Stegmann-SSI protocol
• Digital frequency coupling
(from version 12.00.00)
• HTL encoder at the digital DI1/DI2 or DI6/DI7 input terminals

Danger!
• If the encoder/resolver is used as motor encoder:
Safe operation of the motor is no longer ensured in the event of an error!
• If servo control (SC) or V/f control (VFCplus + encoder) are used: For safety reasons,
always select "Fault" (Lenze setting) in the following parameters as a response for the
(open-circuit) monitoring of the encoder!
• C00586 : Resp. open circuit HTL encoder
• C00603/1 : Resp. open circuit MultiEncoder
• C00603/2 : Resp. open circuit resolver
• If an HTL encoder is used at the digital input terminals:
Observe the maximum input frequencies of the digital inputs!
• DI1/DI2: max. 200 kHz
• DI6/DI7: max. 10 kHz
• To avoid interference when using an encoder, only use shielded motor and encoder
cables!

Note!
Speed feedback is essential for the following motor control modes with feedback:
• Servo control (SC)
• V/f control (VFCplus + encoder)
