9.2.1 SERVOPACK Setup Procedure
The setup procedures for combinations of a linear servomotor with hall sensor and those for combinations of a
linear servomotor without a hall sensor are different. Use the setup procedure appropriate for the system being
used.
9.2.2 Setup Procedure Using Linear Servomotors with Hall Sensors
Perform the following steps 1 to 7 in order.
(1) Installation and Wiring of the Linear Servomotor and Linear Scale
Install the coil assembly and linear scale so that the motor forward direction and linear scale count up direction
are the same.
If the motor forward direction and linear scale count up direction do not match and the linear servomotor is
run in this state, the linear servomotor may not operate or overrun may occur.
When using linear Σ-series servomotors, the motor forward direction (coil assembly’s movement direction when
current flows through phases U, V, and W, in that order) is toward the side from which the motor cable is
extended.
The analog 1-V p-p voltage input from the linear scale to the serial converter unit is counted during phase A (cos
signal) progression.
