Installation/Wiring

Encoder Inputs

Encoders must be line driver type, quadrature (dual channel) or pulse
(single channel), 5VDC or 8-15VDC output, single-ended or differ-
ential and capable of supplying a minimum of 10mA per channel.
Maximum input frequency is 250 kHz.

Encoder inputs are available at TB3. The interface board is jumper
selectable to accept a 5V TTL or 12V DC square-wave with a
minimum high state voltage of 3.0V DC (TTL) or 7.0V DC (12 volt
encoder). Maximum high state voltage is 18.5V DC (board damage
could result if voltage is exceeded). Maximum low state voltage is
0.4V DC. See Encoder & Communications Cabling on page

Important:

Correct direction of motor rotation as determined during
start-up (see Chapter 5) may require that the A or B
channel wiring be reversed.

For Single-Channel applications, eliminate the B and B (NOT) connections. Some encoders may label
the "A" connection as "Signal." Single-channel provides speed indication Only, Not direction.
