3.3. Main Circuit Wiring
This section shows typical examples of main circuit wiring for XtraDrive
Series servo products, functions of main circuit terminals, and the power ON
sequence.
Observe the following precautions when wiring.
CAUTION
•
Do not bundle or run power and signal lines together in the same duct. Keep power and
signal lines separated by at least 30cm (11.81 in).
Not doing so may cause a malfunction.
• Use twisted pair wires or multi-core shielded-pair wires for signal and encoder (PG)
feedback lines.
The maximum length is 3m (118.11 in) for reference input lines and is 20m (787.40 in) for PG
feedback lines.
• Do not touch the power terminals for 5 minutes after turning power OFF because high
voltage may still remain in the servo amplifier.
Make sure the charge indicator is out first before starting an inspection.
•
Avoid frequently turning power O N and OFF. Do not turn power ON or OFF more than
once per minute.
Since the servo amplifier has a capacitor in the power supply, a high charging current flows
for 0.2s when power is turned ON. Frequently turning power ON and OFF causes main power
devices like capacitors and fuses to deteriorate, resulting in unexpected problems.

4.2. Additional Setup Procedures in Trial Operation
For two equipment configurations, which are delineated in the subsequent
sections, precautionary setup procedures must be followed before starting trial
operation.
4.2.1. Servomotors with Brakes
Use a servomotor with a brake for vertical shaft applications or for the
application of external force to the shaft to prevent rotation due to
gravity or external force during a power loss.
The servo amplifier uses the brake interlock output (/BK) signal to
control the holding brake operation when using servomotors with
brakes.

5.1. Settings According to Device Characteristics
This section describes the procedure for setting parameters according to the
dimensions and performance characteristics of the equipment used.
5.1.1. Switching Servomotor Rotation Direction
XtraDrive has a Reverse Rotation mode that reverses the direction of
servomotor rotation without rewiring. Forward rotation in the standard
setting is defined as counterclockwise as viewed from the load.
With the Reverse Rotation mode, the direction of servomotor rotation
can be reversed without changing other parameters. Only the direction
(+, −) of shaft motion is reversed.

Using the /P-CON Signal
Input P-CON CN1-41
The /P-CON input signal switches the Speed Control mode from PI
(proportional-integral) to P (proportional) control.
Proportional control can be used in the following two ways:
• When an operation is performed by sending speed references from
the host controller to the servo amplifier, the host controller can
selectively use the P control mode for particular conditions only.
This method can prevent the occurrence of overshoot and also
shorten settling time.
• If PI control mode is used when the speed reference has a reference
offset, the motor may rotate at a very slow speed and fail to stop
even if 0 is specified as speed reference. In this case, use the P
control mode to stop the motor.

The output circuit is for line-driver output. Connect each signal line
according to the following circuit diagram.
Dividing means converting an input pulse train from the encoder mounted on the servomotor according
Note:
to the preset pulse density and outputting the converted pulse. The units are pulses per revolution (PPR).

Divided encoder signals are outputs; therefore always connect these signal terminals
when a position loop is formed in the host controller for position control.
Set a dividing ratio using the following parameter: PG Dividing Ratio Pn201
The dividing ratio setting is not related to the gear ratio setting (Pn202 and 203) for

IMPORTANT
When using the servo amplifier phase C pulse signal to return to the machine origin,
•
always turn the servomotor at least twice before starting the original return operation.
If the configuration of the mechanical system prevents turning the servomotor before the
origin return operation, then perform the origin return operation at a servomotor speed of
600rpm or below. The phase C pulse signal may not be correctly applied if the servomotor
turns faster than 600rpm.

5.2.5. Using the Electronic Gear Function
The electronic gear function enables the servomotor travel distance per
input reference pulse to be set to any value. It allows the pulses
generated by the host controller to be used for control without having to
consider the equipment gear ratio or the number of encoder pulses.

To move a workpiece 10 mm (0.39 in):
1 revolution is 6 mm. Therefore,
÷
10
6 = 1.6666 revolutions
2048 x 4 pulses is 1 revolution.
Therefore,1.6666 x 2048 x 4 = 13653
pulses are input as reference.
The equation must be calculated at the
host controller.

2. Determine the reference unit used.
A reference unit is the minimum position data unit used to move a
load (minimum unit of reference from the host controller).
To move a t able in 0.001 mm units
Reference unit : 0.001 mm
Determine the reference unit according t o
equipment spec ifications and positioning ac curacy.
Examples (in mm):
• Reference unit can be 0.1in or 0.01in or 0.01mm or 0.001mm,
etc. A reference unit of one pulse moves the load by one
reference unit.
• When the reference unit is 1µm
If a reference of 50000 units is input, the load moves 50mm
(1.97in) (50000 ⋅ 0.001mm = 50mm).
