5. OPERATION AND FUNCTIONS

(b) Initialization of the servo amplifier at the startup of linear servo

1) Before turning the power of servo amplifier on, write the servo parameter initial value, which is unique

to the linear servo, to the flash ROM of QD75MH

referring to the sequence program example

shown in (3) (a) of this section.

2) After completion of writing to the flash ROM, turn the power of servo amplifier on.

POINT

For the linear servo motor on the QD75MH

, the parameter error (37) occurs if

the initialization of servo parameter is not executed.

Writing the initial value to the flash ROM is limited for only once at the startup.

There is no need to write to the flash ROM at the next power-on or later. If the

module write with GX Configurator-QP has been performed, however, initialize

the servo parameter again.

For changing the setting of the parameter No. PD22, add the following program to the sequence

program example shown in (3) (a) of this section, and set the upper stroke limit (FLS) and lower stroke

limit (RLS) to automatically ON.

Servo parameter No. PD002 setting

(When automatically

turning on the FLS and RLS)

When using the FLS and RLS on the controller side, however, do not set them to automatically ON

because both magnetic pole detection signals and input signals are used.
