SINUMERIK Analog Drive Interface for 4 axes ADI 4
2
■
Overview
The SINUMERIK Analog Drive Interface for 4 axes ADI 4 can be
used to operate up to 4 drives with analog setpoint interface.
■
Benefits
7
Connection via PROFIBUS DP
7
Motion Control functionality (isochronous mode)
■
Design
•
4 inputs for incremental encoders (TTL signals) or optionally
4 inputs for absolute encoders (SSI interface)
•
4 analog outputs ± 10 V for the setpoint
•
4 relay contacts for drive enable of axes 1 to 4
•
8 digital outputs (4 drive-specific)
•
10 digital drive-specific inputs
•
Onboard status display on 4 diagnostics LEDs
To supply the module and digital outputs with power, an external
voltage source (+24 V DC) is needed.
■
Integration
The ADI 4 interface module can be used with the following
CNCs:
•
SINUMERIK 840D sl
Several ADI 4 Analog Drive Interfaces can be connected to the
SINUMERIK 840D sl, permitting analog control of all its axes.
Mixed operation of digital drives and ADI 4 modules is possible;
the axes can interpolate with one another.
Encoder connection:
•
TTL incremental encoder with differential transfer:
- Track A and inverted signal A
- Track B and inverted signal B
- Zero signal and inverted zero signal
- Output frequency max. 1.5 MHz
- Phase shift of track A to track B: 90° ± 30°
- Power consumption max. 300 mA
•
Absolute encoder with SSI signal:
- True and inverted output signal
- Shift clock as true and inverted signal
- Transmission frequency max. 750 kbaud
- Power consumption max. 300 mA
Only multi-turn encoders are approved for this purpose.
•
Linear encoder with distance-coded zero marks/reference
marks
- LS 476 C
- LS 186 C with external pulse-shaper electronics EXE
•
Encoder with sin/cos signals can be connected via external
pulse-shaper electronics EXE.
