Speed control
The speed command value is
directly specified to control the
Servomotor rotation.

Unit type
CPU Bus Unit
Special I/O Unit
Unit number alloca-
tion
Unit numbers can be set from 0 to F
(CPU Bus Units).
Unit numbers can be set from 0 to 95.
• One-axis and two-axis PCUs: One unit number
used.
• Four-axis PCUs: Two unit numbers used.
Control method
Commands are executed using MECHA-
TROLINK-II synchronous communications.
Open-loop control is performed using a pulse
train output.
Format of data
exchanged between
PLC and PCU
Binary (hexadecimal)
Example: Present position is output to the PLC
in 32-bit signed binary format.

Speed command
range
Position control:
0 to 2,147,483,647 (command units/s)
(Upper limit speed depends on Servo Drive
and Servomotor.)
Speed control:
−

(percentage of Servomotor’s momentary maxi-
mum rotation speed)
The upper limit of the speed command range
depends on the specifications of the Servo
Drive.
