168 BTAC-02 pulse encoder interface module
Technical data

Encoder interface
The encoder user interface is isolated with reinforced insulation from the DC-
potential.
Encoder type
• Incremental, TTL/HTL encoders
• Differential, single-ended, open collector, and open emitter encoder outputs (refer
to Encoder output types on page 160 )
• Three channels A, B and Z
• Maximum pulse frequency: 200 kHz
• Encoder power supply range: 5…30 V
For the input signal levels, refer to Terminal designations on page 156 .
Encoder interface connectors
Four 3-pin (1×3) spring-clamp type terminal blocks, tin plated, 2.5 mm
2
wire size,
pitch 5.0 mm.
For the terminals, refer to Terminal designations on page 156 .
Cable
The maximum permitted cable length is 100 m.
Encoder and BTAC module power supply
• 50 mA (BTAC) + encoder current consumption (refer to the encoder data sheet)
• Voltage: 5…30 V DC (Depends on the encoder. Refer to the encoder data sheet.)

Back-up power supply for the drive
Refer to Auxiliary voltage connection on page 74 .

Internal connectors
Connector X102 provides encoder interface signals to the drive control board.
Connector X102 data: 1×8 pin header, pitch 2.54 mm, height 33.53 mm.
Connector X100 serves as power supply interface between the BTAC module and the
drive’s control board. It provides back-up power supply in main power loss situations.
Connector X100 data: 2×4 pin header, pitch 2.54 mm, height 15.75 mm.
