7. Regenerative Resistance Unit (Optional)
A regenerative resistance unit is required only when the actuator is used as a vertical axis. It is not required in an
application where the actuator is used as a horizontal axis because the built-in regenerative resistance capacity
is sufficient.
7-1 Number of Units Connected
If the number of regenerative resistance units is insufficient, an “Excess Power Voltage (0C9)” error generates.
Motor wattage Horizontal application Vertical application
0 to 150 W Not required
200 to 600 W 1 unit
750 W
Not required
2 units
7-2 Connection Method
Connect the supplied connection cable to the regenerative resistance unit connector on the controller.
Connecting one unit
Connecting two units
Caution: Connecting two controllers to one regenerative resistance unit is not allowed.
