Description
Specifications

ø50mm shaft type absolute multi-turn rotary encoders EPM50 series makes possible to realize space saving mounting and to implement various user applications by adding side connector type line-ups. Absolute multi-turn encoders EPM50 series provides both absolute position data per revolution and revolution count data with 23 bit high resolution and accuracy. In addition, the series allows more diverse user’s choice with parallel and serial (SSI) transmission type outputs. It can be used for control of an industrial robot or high precision motor.

Main features

● Compact size of diameter ø50mm
● Parallel data / SSI data transmission type
● Total 23bit resolution(8388608 divisions) of 10bit
single-turn(1024 divisions) and 13bit multi-turn (8192 divisions)
● Easy zero adjustment using single-turn / multi-turn data separated reset function
● Memorizing revolution data up to ±90° after blackout without memory back up function
● Possible CW/CCW direction setting with direction function
● Maximizing users convenience with lclear, overflow alarm (OVF) function
● Protection structure IP64(IEC standard)
● Provides Latch function(Parallel output model only)

Applications

* Rotation and position control of the wind turbine generator.

¶ 1: It calibrates the multi-turn counts by comparing single-turn data before/after power off without counting multi-turn counts when power is off. It shall be used on the condition that no over-rated revolution occurred since proper multi-turn data may not be available if any revolutions occurred over ±90° from the position when power is off.
¶ 2: OVF alarm is ON when multi-turn count is out of counting range (0 to 8191 revolution).
It shall be initialized by changing the setting of direction or applying multi-turn count reset or clear signals.
¶ 3: Single-turn data shall be initialized as[0]when single-turn data reset is input.
¶ 4: Multi-turn count shall be initialized as[0 revolution]when multi-turn count reset is input.
¶ 5: High active is customizable.
¶ 6: Make sure that. Max response revolution should be lower than or equal to max. allowable revolution when selecting the resolution.
[Max. response revolution(rpm)= Max. response frequency / Resolution × 60 sec]
¶ Environment resistance is rated at no freezing or condensation.
