(2) Z channel can be used as a pulse input while A and B are used for encoder.
5 Encoder Z
4 Encoder B (NOT) Quadrature B input.
3 Encoder B
2 Encoder A (NOT) Single channel or quadrature A input.
1 Encoder A
Type: Incremental, dual channel
Supply: 12V, 250 mA. 12V, 10 mA minimum inputs isolated with differential transmitter,
250 kHz maximum.
Quadrature: 90°
, ±
27° at 25 °C.
Duty Cycle: 50%, +10%
Requirements: Encoders must be line driver type, quadrature (dual channel) or pulse (single
channel), 8…15V DC output (3.5…6V DC when jumpers are in 5V position),
single-ended or differential and capable of supplying a minimum of 10 mA per
channel. Maximum input frequency is 250 kHz. The Encoder Interface Board
accepts 12V DC square-wave with a minimum high state voltage of 7.0V DC. With
the jumpers in the 5V position, the encoder will accept a 5V DC square-wave with
a minimum high state voltage of 3.1V DC. In either jumper position, the maximum
low state voltage is 0.4V DC.
