1-8 Operating display panel
The HA-655 driver provides a 6-digit LED display and four operation keys on the front panel. The panel
executes monitoring, tuning, setting, and JOG operation.
1-8-1 Outlines of operation modes
The HA-655 driver provides the following four modes: monitoring, tuning, setting, and operations.
◆ Monitor mode
The HA-655 driver displays position and speed commands, a current position from a motor-encoder, a
pulse count in an error counter, states of input and output signals, load conditions, alarm histories, and a
code number for the actuator for which the driver is set. The mode can be used for diagnosing an
abnormal driver.
After power supply, the monitor mode starts up and works as the hub of other three modes for operation.
◆ Tune mode
The tuning mode includes various parameters to control the actuator motion. Setting the most suitable
value for each parameter obtains the optimum performance of the actuator.
◆ Parameter mode
The parameter mode sets various parameter values relating to the fundamental operational functions
such as: specifications of the position mode or the speed mode, configurations of input signals, an
electronic gear function, limiting values of speed and torque, and parameters to communicate with a
host.
◆ Test mode
The test mode includes required functions for system tests; such as JOG operation functions, operations
of pseudo output signals, I/O signal monitors, and so on.
1-8-2 Selecting a mode
After powering the driver, the monitor mode starts up automatically. The [ADJ] and [SET] keys select a
mode.
