Chapter 1Outlines of <strong>HA</strong>-<strong>655</strong> driver<br />
The <strong>HA</strong>-<strong>655</strong> series are dedicated servo drivers for F<strong>HA</strong> -C series actuators, which are axially compact<br />
and feature a large through-hole. The actuators utilize <strong>Harmonic</strong> <strong>Drive</strong>® gear components for precise<br />
motion control and super flat AC servomotors.<br />
The <strong>HA</strong>-<strong>655</strong> drivers provide many superior functions to allow the F<strong>HA</strong>-C actuators to excel in<br />
performance.<br />
1-1 Main features<br />
Easy parameter setting<br />
Parameters have been set to match the driver with the F<strong>HA</strong> -C series actuator you have ordered. No<br />
setting for the actuator is necessary by users.<br />
The <strong>HA</strong>-<strong>655</strong> series provides four modes that can be adjusted by end users: monitor mode, tune mode,<br />
parameter mode, and test mode. Parameters of these modes are indicated on a front panel of the driver<br />
using a 7-segment LED display and are easily set.<br />
Substantial monitoring functions<br />
The monitor mode indicates various operational parameters and makes it possible to indicate the<br />
required parameters for the servo system; such as commands, feedback, or an error counter.<br />
Up to eight previous alarms are also indicated as alarm history that is helpful for diagnosis.<br />
Individual control power supply<br />
It is possible to troubleshoot safely because the control power supply is individuated from the main.<br />
Easy test operation<br />
The test mode helps testing a servo system by JOG operation with keys on the front panel.<br />
Monitoring and operating I/O ports with the keys also help checking command sequences of a host<br />
without actuator motions.<br />
Complex encoder cable<br />
Improvement of data transmission with an encoder saves its wires resulted in increased reliability and<br />
simplified wiring.<br />
Optional absolute encoder<br />
The optional encoder system surely keeps its current position all the time, even in power failure.<br />
Electronic gear suitable for mechanical system<br />
The electronic gear function adjusts commands to a feed pitch of a driven mechanism such as gears or<br />
lead screws.<br />
Three types of input signals for position commands<br />
Three types of input signals for the position command are selectable: two-pulse train (Forward Pulse,<br />
Reverse Pulse), single-pulse train (Step and Direction), and two phase pulse train (Quadrature Input<br />
Signals).<br />
