Schneider DAV 107 | Logistat Positioning Module

The Schneider DAV 107 controls positioning for single-axis servo systems. This Logistat module manages acceleration, deceleration, and target positioning accurately. You can use it for conveyors, cut-to-length machines, or indexing tables. The module operates as part of a Telemecanique Logistat control system.

Positioning and Control Specifications

Parameter	Specification
Brand	Schneider Electric
Model	DAV 107
Product Type	Logistat Positioning Module
Axis Control	Single axis
Position Feedback	Incremental encoder (5 VDC)
Max Encoder Frequency	100 kHz

Position Range	0 to 16,777,215 counts

The Schneider DAV 107 reads encoder pulses for precise position tracking. This positioning module generates a ±10 VDC signal for servo drive control. You can program up to 99 independent positioning moves. The unit stores these move profiles in its internal memory.

Physical Dimensions and Weight

Parameter	Specification
Weight	0.42 kg (0.93 lbs)
Height	130 mm
Width	45 mm (2 slots)
Depth	140 mm
Mounting	Logistat rack
Connector Type	2 x 15-pin DIN

This Logistat module weighs 0.42 kg for secure rack mounting. The unit occupies two slots in a Logistat chassis. Its height reaches 130 mm with the front panel included. You can insert the Schneider DAV 107 alongside other Logistat modules.

Interface and Connectivity

A 15-pin D-sub connector handles encoder input signals. A second 15-pin D-sub connector provides analog output and I/O access. You will find 14 screw terminals for discrete field wiring. These terminals accept wire sizes from 0.2 to 1.5 mm². The front panel includes 12 LED indicators for status monitoring.

Energy Storage and Memory

The Schneider DAV 107 uses a supercapacitor for parameter retention during power loss. This capacitor stores enough energy for 72 hours of data preservation. For longer retention, an optional lithium battery (DAV 106 BAT) provides 5 years of backup. The module’s internal RAM holds 8 KB of positioning profiles and configuration data. A small EEPROM stores factory calibration values permanently.

Internal Components and Construction

Two microcontrollers manage motion profiling and I/O processing independently. The analog output stage uses a 12-bit digital-to-analog converter. Twenty-eight optocouplers isolate field I/O from the internal logic. The Schneider DAV 107 contains 16 precision resistors for encoder signal conditioning. A quartz crystal provides a 20 MHz timing reference for motion calculations.

Operational Features and Use

This positioning module accepts incremental encoder inputs with A, B, and Z channels. You can configure software limits to prevent mechanical overtravel. The unit supports point-to-point positioning with programmable S-curve or trapezoidal profiles. Transitioning to this module eliminates external cam switches and limit relays. Use the Schneider DAV 107 for flying shears, winding machines, or pick-and-place units. For best results, pair this module with a compatible servo drive and encoder.
