Specification for all encoder inputs
Differential comparator accepts two-phase quadrature
incremental encoders with differential (recommended) or
single-ended outputs. Max. frequency is 1.6 MHz. Minimum
time between transitions is 625 ns. TTL-compatible voltage
levels: Low
£ 0.4V, High ³ 2.4V. Maximum input voltage is
5VDC.
Requirements for Non-Compumotor Encoders
• Use incremental encoders with two-phase quadrature output. An index or Z channel output is optional.
Differential outputs are recommended.
• It must be a 5V (< 200mA) encoder to use the OEM6250’s +5V output. Otherwise, it must be separately
powered with TTL-compatible (low £ 0.4V, high ³ 2.4V) or open-collector outputs.
• If you are using a single-ended encoder, leave the A–, B– and Z– terminals on the OEM6250 unconnected.
