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.
