Table 10: Product – ES860 Encoder board compatibility

The ES860 Sin/Cos Encoder board allows interfacing encoders provided with 1Volt peak-to-peak analog outputs. Those encoders may be used to provide speed feedback and/or position feedback for Santerno drives.

NOTE

Please refer to the Programming Guide and the Guide to the Synchronous Motor

Application for the available control algorithms.

The ES860 board may be configured to operate in two acquisition modes as follows:

•

Three-channel mode : increments low speed resolution and is suitable for slow rotation speed actuators requiring very accurate measurement of speed and position.

•

Five-channel mode: detects the absolute mechanical position as soon as the inverter is first started up.

The board features are given below:

Acquisition of five 1Volt peak-to-peak analog inputs on balanced line

Two channels acquired via zero crossing and bidirectional digital counter with quadrature direction discriminator and x4 resolution multiplication factor (e.g. 1024 ppr to 4096 ppr)

Zero index control for accurate alignment

Two channels acquired in analog mode for absolute angle detection (12-bit resolution)

Max. 140kHz input frequency in zero crossing channels for speeds up to 800rpm with 1024 ppr; alternatively up to 2000rpm with 4096 ppr

Maximum 1kHz input frequency in analog channels

Ability to re-direct analog signals to zero crossing channels

Galvanic isolation in all channels for both digital and analog inputs

5V and 12V power supply output allowing fine tuning of the output voltage, isolated from the common for power supply output and signal output of the inverter.
