In combination with other single-turn iCs encoders with a multi-turn interface, such as the iC-MHM and iC-MU for magnetic encoders or the iC-LGC for
optical encoders, multi-turn resolutions of up to 46 bits can be achieved. When combining the iC-MHM Hall encoder with the iC-PV, the same magnet can be used for both encoders.
The iC-PV automatically switches to battery operation in the event of a power outage or low voltage in the operating supply. This ensures continuous acquisition of multi-turn data, even when the application is unpowered (power cut). Upon power-up, the iC-PV
continuously transmits multi-turn data to the single-turn device, which then provides the absolute position. Synchronization of multi-turn data with
single-turn data occurs automatically via a CRC-secured transmission protocol to the single-turn encoder. The iC-PV is
functionally self-monitored (10-bit CRC protection of the counter configuration and registers, magnetic field monitoring, and supply voltage monitoring
) and detects signal errors at the NERR output or in the serial transmission of multi-turn data. The iC-PV can also function as a single-turn iC encoder
with 3-bit octal resolution and parallel data output.
Typical applications include:
- Gearless tachometer
- Multi-turn magnetic absolute encoder
- Magnetic period counter
- Electronic consumption counter
- Simple octal encoder with 10 μA current consumption
- 40-bit digital control button with ultra-capacity buffer
- Hollow shaft magnetic encoder with 1-chip iC-MU encoder. Powered by a 3.0 to 5.5 V supply, the iC-PV operates in the industrial
temperature range of -40 to 125 °C. Configuration data is automatically loaded from an external EEPROM after connection.
