5. Parameter Settings

Default movement direction for excitation-phase signal detection (No. 28 PHSP1)

Excitation-phase detection is performed at the first servo ON after the power is input. Define the detection
direction at this time. This setting need not be changed in normal conditions of use. However, if the actuator
contacts the mechanical end or an obstacle and cannot be moved by hand when the power is input, this setting
must be changed to the direction in which the motor is easier to operate.
Set the value of parameter No. 28 to 0 or 1. If the detection direction is the same as the home return direction, set
the same value as that in parameter No. 5 (home return direction).
To make this direction opposite the home return direction, set a value other than that in parameter No. 5 (home
return direction).

This parameter is valid only when the pole sense type is the current suppression scheme.

(Example 1) Motor upper-side vertical installation + If the power is input when the slider is contacting the lower

mechanical end:

(Example 2) Motor lower-side vertical installation + If the power is input when the slider is contacting the lower

mechanical end

Excitation-phase signal detection time (No. 29 PHSP2)

Excitation-phase detection is performed at the first servo ON after the power is input. Define the detection time
(excitation switching cycle) at this time.
The factory setting is the detection time in accordance with the standard specifications of the actuator and this
setting need not be changed in normal conditions of use.
Should an excitation detection error or a malfunction occur at the first servo ON after the power is input, the
detection time set in parameter No. 29 can be changed as one of the remedies.
Before changing this parameter, contact us.

Pole sense type (No. 30 PHSP)

Magnetic pole detection operation is performed at the first servo ON after the power is input, and the operating
mode at this time is defined in parameter No. 30.
This setting need not be changed in normal conditions of use, so it must not be changed by the customer.
Definition of set value: 0 (Current restraint)

1 (Distance restraint)

The factory setting is 1 (distance restraint).
