Capacitor

Electrical InterfaceIt is recommended that the CH.A, CH.B and CH.I outputs be pulled up with a resistor of 2.7kΩ(±10%) in order to shorten the rise time of the output pulse. To reduce electrical noise it is recommended that a capacitor be added across Vcc-GND.For best results the capacitor should be placed as close to Vcc as possible. The capacitor's value should be adjusted to determine an acceptable level of noise.

Definition of Key Terms

CPR: Count Per Revolution. Resolution for rotary type encoder. Number of pulses for one revolution.

One Cycle: 360 electrical degrees (Oe) , 1 bar and window pair.

One Shaft Rotation: 360 mechanical degrees, N cycles. One rotation of the codewheel.

Position Error (Δθ) : The normalized angular difference between the actual shaft position and the position indicated by the encoder cycle count.

Cycle Error (ΔC): An indication of cycle uniformity. The difference between an observed shaft angle which gives rise to one electrical cycle, and nominal angular increment of 1/N of a revolution.

Pulse Width (P): The number of electrical degrees that an output is high during 1 cycle. This value is nominally 180Oe of 1/2 cycle.

Pulse Width Error (ΔP): The deviation, in electrical degrees, of the pulse width from its ideal value of 180Oe.

Logic State Width (S1～ S4): The number of electrical degrees between a transition in the output of channel A and the neighboring transition in the output of channel B. There are 4 states per cycle, each nominally 90Oe.

Logic State Width Error (ΔS): The deviation, in electrical degrees, of each state width from its ideal value of 90Oe.

Phase (Ø): The number of electrical degrees between the center of the high state of channel A and the center of the high state of channel B. This value is nominally 90Oe for quadrate output.

Phase Error (ΔØ): The deviation of the phase from its ideal value of 90Oe.

Direction of Rotation: When the codewheel rotates in the counterclockwise direction (as viewed from the encoder end of the motor), channel A will lead channel B. If the codewheel rotates in the clockwise direction, channel B will lead channel A.

Index Pulse Width (Po): The number of electrical degrees that an index output is high during one full shaft rotation. This value is nominally 90Oe or 1/4 cycle.
