2-4-1 Indicating of pulse counts<br />
Chapter 2Functions<br />
As shown in the figure to the right, the motion<br />
command pulses are transmitted to the <strong>HA</strong>-<strong>655</strong><br />
driver from a host. The driver drives the actuator<br />
corresponding to the motion command. When the<br />
actuator starts, the position pulses are sensed by<br />
the encoder and are fed back to the driver. The<br />
<strong>HA</strong>-<strong>655</strong> driver continues to drive the actuator until<br />
the error count (difference between command count<br />
and feedback count) comes to zero.<br />
In the monitor mode, [command pulse], [feedback pulse], and [error pulse] can be monitored. This<br />
function may be effective for diagnosis.<br />

2-4-2Manual JOG operation<br />
It is possible to operate the actuator manually for test, for tuning, and for diagnosis without commands<br />
from a host. Pressing the [UP] and [DOWN] keys on the front panel rotates the actuator at pre-set speed<br />
and at pre-set acceleration.<br />
Operation and setting<br />
[Test mode][Jo: JOG operation], [SP: JOG speed], [Ac: JOG acceleration]<br />
2-4-3Monitoring inputs and operating outputs<br />
It is possible to monitor input ports of [clear], [servo -ON], [FWD inhibit] and [REV inhibit] for test, for<br />
tuning, and for diagnosis.<br />
It is also possible to manually output signals of [in-position], [attained speed], [alarm] and so on without<br />
relations to the actuator state by pressing the [UP] and [DOWN] keys on the front panel outputs signals.<br />
