10.3 Encoder Option MCB 102The encoder module can be used as feedback source for closed loop Flux control (par. 1-02Flux Motor Feedback Source) as well as closed loop speedcontrol (par. 7-00Speed PID Feedback Source). Configure encoder option in parameter group 17-xxUsed for:• VVCplus closed loop• Flux Vector Speed control• Flux Vector Torque control• Permanent magnet motorSupported encoder types:Incremental encoder: 5 V TTL type, RS422, max. frequency: 410 kHzIncremental encoder: 1Vpp, sine-cosineHiperface® Encoder: Absolute and Sine-Cosine (Stegmann/SICK)EnDat encoder: Absolute and Sine-Cosine (Heidenhain) Supports version 2.1SSI encoder: AbsoluteEncoder monitor:The 4 encoder channels (A, B, Z, and D) are monitored, open and short circuit can be detected. There is a green LED for each channel which lights upwhen the channel is OK.NB!The LEDs are only visible when removing the LCP. Reaction in case of an encoder error can be selected in par. 17-61Feedback SignalMonitoring: None, Warning or Trip.When the encoder option kit is ordered separately the kit includes:• Encoder Option MCB 102• Enlarged LCP fixture and enlarged terminal coverThe encoder option does not support AutomationDrive FC 302 frequency converters manufactured before week 50/2004.Min. software version: 2.03 (par. 15-43Software Version)ConnectorDesigna-tionX31IncrementalEncoder(please refer toGraphic A)SinCos EncoderHiperface®(please refer toGraphic B)EnDat Encoder SSI Encoder Description1 NC 24 V* 24 V Output (21-25 V, Imax:125 mA)2 NC 8 Vcc 8 V Output (7-12 V, Imax : 200 mA)3 5 VCC 5 Vcc 5 V* 5 V Output (5 V ± 5%, Imax: 200 mA)4 GND GND GND GND5 A input +COS +COS A input6 A inv input REFCOS REFCOS A inv input7 B input +SIN +SIN B input8 B inv input REFSIN REFSIN B inv input9 Z input +Data RS485 Clock out Clock out Z input OR +Data RS48510 Z inv input -Data RS485 Clock out inv.
