4.3.1 Positioning Parameters
Setting the units used
PARA. 0: System of units
Set the units used for the position and the speed.
In accordance with the setting of PARA. 0, the parameters are expressed in the units shown in
the table below.
PARA. 1 and PARA. 2 are valid only when PARA. 0 is set to "0 (mechanical system of units)" or
"2 (combined system of units)".
They are ignored when PARA. 0 is set to "1 (motor system of units)".
The relationship between the motor system of units and the combination system of units is
expressed in the following formula.
PARA. 1: Pulse rate (The pulse rate is expressed as "A".)
Set the number of pulses per rotation of the motor to be given to the drive unit.
• When the servo motor is equipped with an electronic gear, its magnification should be taken
into account. The relationship between the pulse rate and the electronic gear is as follows.
Pulse rate (PARA.1) = Resolution of encoder (positioning feedback pulse)
/ Electronic gear (CMX/CDV)

Setting = "0" :Controls the position based on "mm, deg, 1/10 inch, etc.", which is called the mechani-
cal system of units.
Setting = "1" :Controls the position based on "PLS" (pulses), which is called the motor system of
units (initial value).
Setting = "2" :Controls the position using the mechanical system of units and the speed using the
motor system of units, which is called the combined system of units.
