System componentsDistributed I/OADI 4 (Analog Drive Interface)8■ OverviewThe ADI 4 Interface Module (analog drive interface for 4 axes)can be used to operate up to 4 drives with analog setpoint interfaceon the isochronous PROFIBUS DP. These can be electricalor hydraulic drives. The ADI 4 can also be used as an externalencoder for SIMOTION.■ ApplicationThe actual values (encoder values) are transmitted from theADI 4 Module over PROFIBUS DP to the Motion Control systemSIMOTION. The position controller in SIMOTION calculates thespeed setpoint value. This value is transmitted over PROFIBUSDP to the ADI 4 Module and output as an analog value there.The ADI 4 Module is not a DP standard slave which is compliantwith the PROFIDrive profile and is therefore only approved foruse in conjunction with SIMOTION C/P/D, SINUMERIK802D/840Di (see Catalog NC 60) or SIMATIC CPU 317T-2 DP(see Catalog ST 70). For this reason, the ADI 4 Module does notsupport acyclic communication, for example.The ADI 4 Module must be operated on an isochronousPROFIBUS DP with DP cycle times from 1 ms.■ DesignThe following interfaces and status indicators are available whenusing ADI 4 with SIMOTION:• Connection via PROFIBUS DP to Motion Control functionality(isochronous, max. 12 Mbit/s)• 4 inputs for incremental encoder (TTL signals) or optionally4 inputs for absolute encoder (SSI interface).Encoders with SINE/COSINE signals (1 Vpp) can be connectedusing external pulse shaping electronics (EXE) whichconvert the signals to the 5 V TTL level.• 4 analog outputs ±10 V for the setpoint• 4 relay contacts for drive enable (axes 1 to 4)• 8 digital outputs- DO 1 to DO 4- DO 5 to DO 8, general outputs or axis-specific directionsignal for axes (for SIMOTION: general outputs only)• Relay contact 1 and 2 (not supported by SIMOTION)• 10 digital drive-specific inputs- BERO 1 to BERO 4- Sensor 1 and sensor 2- Ready signal "Drive Ready" for axes 1 to 4• Onboard status display on 4 diagnostics LEDsAn external power supply (+24 V DC) is required for the moduleand the digital outputs.■ FunctionThe following functions are available in conjunction withSIMOTION:• Speed-controlled axes• Position-controlled axes• External encoders for SIMOTION• Homing over BERO or• Homing over zero marks (non-distance-coded zero marks/reference marks)• Measuring over sensor 1 and sensor 2 (one edge, rising orfalling)8/26 Siemens PM 10 · 2005
