Технические данныеPress 2000M7 Press control system
Control system design
Central controller
- Standard systems: SIMATIC S7-300 and SIMATIC M7
- Centralized/distributed I/O (S7 standard)
- Use of S7 FMs (FM 351, FM 352, FM 354)
- Press technology tasks on Press2000M7 module
Operator panel SIMATIC Ops
Main drive control
Punch positioning 0,1 ° with SSI absolute value encoders (controlled by FM 352)
Speed control (±10 V) for stroke number entry
Positioning of main drive (open or closed-loop) for stroke height adjustment
Positioning accuracy 0,1 °
TDC stop control via brake angle calculation
Implemented on Press2000M7 module
Cam controller
Use of FM 352 with 128 cams on 32 tracks, including 13 direct outputs
SSI absolute encoder measurement system (single-turn, traversing range modulo 360 º)
Brake cam for TDC stop, brake limit via main drive control
Positioning axes
Use of FM 351 and FM 354
Incremental or SSI absolute value encoder
Max. 3 positioning axes
Positioning with open or closed-loop position control
Press force monitoring
Up to 4 measuring sensors, ±10 V; ±20 mA ; 35 µs conversion; 16-bit resolution
Minimum, maximum, sum and differential force monitoring
