8.6 Parameter Unit
A Parameter Unit is required to operate and monitor the Servo Driver from a remote location or
from a control panel. To connect the Parameter Unit to the Servo Driver, use a special Parameter
Unit cable and connect it to the CN3 connector on the front panel of the Servo Driver.
One meter of cable is provided with the Parameter Unit. If a distance of one meter between the
Parameter Unit and the Servo Driver is not enough, purchase a 2-m Parameter Unit cable
(R88A-CCW002C) separately.
Note 1.
With a DeviceNet Unit mounted, a DeviceNet communications timeout will occur if a Servo
Driver Parameter Write Command data is sent via DeviceNet while a Parameter Unit is con-
nected or while communications with a personal computer are in progress.
2.
With a DeviceNet Unit mounted, the LED indicators on the front panel of the Servo Driver will
turn OFF when a Parameter Unit is mounted, and turn ON again when it is removed. This is not
a malfunction. The LED indicators will also turn OFF in the following circumstances:
• At power-up (for approximately 3 s).
• When data tracing is executed via DeviceNet.
• When Servo Driver Parameter Read or Write Command data is sent via DeviceNet or
from the Setup Tool. (The indicators turn OFF momentarily.)
