Description

The MSX-RDC-17 is a device for supplying and acquiring a resolver. It converts the position value given by the resolver into a digital incremental output signal. The resolution of the incremental encoder output can be defined using the switch on the front side of the MSX-RDC-17.

Features

Power supply

• Nominal voltage: 5 V variant: +4.9 to +5.25 V, 135 mA @ 100 rps / 16-bit
• Overvoltage protection: 5 V variant: 5V TVS (Vbr 6.4-7 V, Vclamp 9.2 V, 400 W)

Resolver output/input

• Frequency: programmable 2 kHz to 20 kHz in 250 Hz steps

Incremental encoder output

• Output signals: incremental A+, A-, B+, B-, Index+, Index-
• Output type: differential, RS422
• Resolution: 10-/12-/14-/16-bit

Factory-configured by ADDI-DATA, not user-modifiable.

Power supply connector

For the power supply of the MSX-RDC-17, a 4-pin screw terminal is fixed on the bottom side of the housing. The Ground and the supply pins are connected internally with each other. For less current flow over the terminals, please connect all four pins externally with each other!

Resolver connector

The resolver has to be connected to the 9-pin D-Sub female connector on the front side of the MSX-RDC-17.

Reset button

On the front side of the MSX-RDC-17, a recessed reset button is provided. Pressing the button briefly performs a hardware reset of the device, reinitializing the resolver-to-digital converter and restoring normal operation. The button is intended for occasional use only, it does not need to be held and should not be actuated during normal operation.

Incremental encoder output

The incremental encoder signals are available at the 9-pin D-Sub male connector of the MSX-RDC-17.

Environmental conditions

• Operating temperature: 0-60°C (with forced ventilation)
• Storage temperature: -25°C to +70°C
• Relative air humidity at indoor installation: 50% at +40°C | 80% at +31°C

Index signal (incremental encoder output)

An Index pulse is generated when the absolute angular position passes through 0.

Intended use

The resolver-to-digital converter MSX-RDC-17 has to be used as electrical equipment for measurement, control and laboratory pursuant to the standard DIN EN IEC 61010-1. The power supply for the resolver-to-digital converter MSX-RDC-17 must fulfil the requirements of DIN EN IEC 62368-1 and DIN EN 55032 or IEC/CISPR 32 and DIN EN 55024 or IEC/CISPR 24.

Usage restrictions

The resolver-to-digital converter MSX-RDC-17 must not be used as a safety-related part (SRP).
