1-10 Rotary direction
Forward rotary direction is defined as clockwise (CW)
rotation viewing the output flange of the actuator when
a driver of HA655 and HA-675 signals forward commands.
The direction can be reversed by the setting of
[parameter mode]→[8: rotary direction] of the driver.
Value FWD command REV command Setting
0 FWD rotation REV rotation Default
1 REV rotation FWD rotation
1-11 Impact resistance
The actuators are resistant to impacts along the radial axes.
Impact acceleration: 294 m/s
2
However, do not apply impact to the output flange.
1-12 Vibration resistance
The allowable vibration from all directions is as follows:
Vibration acceleration: 24.5 m/s

(Frequency:10~400Hz)
1-13 Torque-speed characteristics
The following are actuator speed-torque characteristics in combination
with a proper the HA-655 and HA-675 driver showing allowable
duty range. Refer to chapter 2 [selection guidelines] for using
the FHA-C series actuators most suitably.
• Continuous duty range
The range allows continuous operation for the actuator.
• 50% duty range
The range allows the 50% duty time operation of a cycle time.
Refer section 2-4-5 [duty cycle].
• Acceleration and deceleration range
The range allows instantaneous operation like acceleration and deceleration, usually.
The continuous and 50% ranges in each graph are measured on the condition of the
FHA-C actuator attached on the heat radiation plate described in the figure.
