3-3 Setting the initial parameters for the servo drive unit
(Standard specifications)
The servo parameters must be set before the servo system can be started up. The servo parameters
are input from the NC. The input method differs according to the NC being used, so refer to each NC
Instruction Manual.
3-3-1 Setting the standard parameters
When starting up the system, first set the standard parameters listed in "3-3-2 List of standard
parameters for each servomotor". For the parameters shown below, check the machine and servo
system specifications and determine the setting value.
(1) Basic specification pa rameters
[1] When performing absolute position control, set SV017/bit7=1. This may be automatically set by
NC system parameter setting, depending on NC model. (Setting on the servo parameter screen
is not valid.)
[2] For HA053N, HA13N, HA23N, HA33N motors, if the connector direction of the motor end
detector with motor power supply connector is 90°, se t SV017/bit5=1. If the angl e is 180°, use a
standard setting (SV017/bit5=0).

POINT
Setting of absolute position control (SV017/bit7) may be set automatically by NC
system parameter setting, dependi ng on NC model. In this case, setting on the serv o
parameter screen is not valid.

(a) For semi-closed loop control
For control using only the motor end detector, specify the settings shown in the table below. For
speed and current synchro nous control, refer to sectio n "2-4-3 Connecting the synchron ous control

(b) For full-closed loop control
Some parameter settings must be specified in order to use the machine end detector. These
settings are determined by type or the installation conditions of the linear scale and the ball screw
end detector.
[1] The SV025/bit8 to B (ent) setting must be specified according to the motor end detector
specifications, in the same manner as for semi-closed loop control. For current synchronous
control, however, refer to section "2-4-3 Connecting the synchronous control system".
[2] If the polarities of the motor end detector and the machine end detector do not match, specify
SV017/bit4=1 setting.
[3] To use AT342, specify SV027/bit6=1 setting.
[4] To use the MP scale, specify SV017/bit8 setting in accordance with the scale specifications.
For absolute position control, spe cify SV017/bit9=1 setting.
[5] For ABZ phase pulse output type relative position detection scale with constant Z-phase
detection position without regard to the travel direction, specify SV027/bit6=1 setting. Z-phase
detection occurs as follows: Plus-direction travel: Rising edge detection, Minus-direction
travel: Falling edge detection
[6] For machine end absolute position control at the rotation axis, specify SV081/bit1=1 setting.
[7] For speed and current synchronous control, refer to "2-4-3 Connecting the synchronous
control system".
