Connecting The I/O Signals; Terminal Blocks Pin Assignments - Vexta CFK II Series Operating Manual

Connecting the I/O signals

Connecting the I/O wires into the driver's I/O signal terminal blocks (TB3).
Note
• For the I/O signal cable, use twisted pair with a diameter equivalent to at least AWG24 to
22 (0.2 to 0.34 mm
possible [6.6 ft. (2 m) max.].
• Separate I/O signal cables at least 12 in. (300 mm) from electromagnetic relays and
other than inductance loads. Additionally, route I/O signal cables perpendicular to power-
supply cables and motor leads, rather than in a parallel fashion.

∗ Depends on the setting of the pulse-input selector switch.
• When this switch is set to 1-pulse input mode, the inputs are the pulse input and the
rotation-direction input.
• When this switch is set to 2-pulse input mode, the inputs are CW and CCW.
