7.2 Connection Example with Servo Driver

In this section, we use Panasonic Servo Driver as an example to show

how to connect it with PCI-8134. Figure 7.3 show the wiring.

Note that:

1. For convenience’ sake, the drawing shows connections for one axis

only.

2. Default pulse output mode is OUT/DIR mode; default input mode is 4X

AB phase mode. Anyway, user can set to other mode by software

function.

3. Since most general purpose servomotor driver can operates in

Torque Mode; Velocity Mode; Position mode. For linking with PCI-

8134, user should set the operating mode to Position Mode. By setting

servo driver to this mode, user can use PCI-8134 to perform either

Position Control or Velocity Control.

4. The Deviation Counter Clear input for Panasonic Driver is line drive

type where ERC output of PCI-8134 is open collector type. So a little

circuit is required for interfacing.
