1. Converter Overview 1-1. Overview This manual describes the specifications and instruction procedures for the VE-2PR/VM-2PR STYLE1 which is used together with PROFIBUS-DP. The VE-2PR/VM-2PR STYLE1 incorporates a rotary position sensor to detect the position of the machine being controlled. The VE-2PR/VM-2PR STYLE1 is used with the ABSOCODER sensor. The ABSOCODER sensor uses a magnetic position detection format, thereby eliminating the need for the incremental format encoder which other position detection systems require.
1-2. Features VE-2PR/VM-2PR STYLE1 ABSOCODER converters offer the following features. 1 .Absolute position detection: The ABSOCODER sensor is an absolute position sensor featuring our unique position detection principle. The absolute sensing guarantees accurate position detection even when the power is shut off, or when accidental noise occurs. Outstanding sensor durability is achieved by a non-contact position sensing design.

4. Installation 4-1. Converter Installation Conditions & Precautions ●Installation Site (1) Avoid sites where the unit is exposed to direct sunlight. (2) The ambient temperature should never exceed a 0-55℃ range. (3) The ambient humidity should never exceed a 20-90% RH range. (4) Do not install the unit in areas where condensation is likely to occur (high humidity with extreme temperature changes).
4-3. Wiring 4-3-1. Converter & Sensor Connection The ABSOCODER converter and ABSOCODER sensor connection is described below. The maximum extension sensor cable length varies according to the ABSOCODER sensor and cable models being used. (Refer to section 2-2 for details. ) ●...
4-3-2. Power Supply Connection The power supply should be connected as described below. (1) Power Supply - Rush current: 10 A (rush time of 20 ms) - The input power supply (24 VDC, 10 W or more, 8 A or less) should be isolated from the commercial power supply - Use the R4 type crimp lug terminals with insulating sleeves in order to prevent shorting caused...

6-2. Preset Data (Output Data: Master Slave) The master can change the position data to any desired value by performing a preset function using Output Data. The changed position data is stored in the converter's non-volatile memory. Therefore there is no need to perform a preset function each time the power is turned on.
Page 27
(1) Preset timing The current position data is changed by the preset data (PRD0-PRD23) and axis PRESET signal (1 bit) which are written from the master. The response time from the point when the axis PRESET signal changes from “0” to “1”, until the current position data setting occurs, is shown below.
