Features

(1) Analog output type that possesses a deviation counter and D/A converter
inside
This module converts command pulse for positioning into analog voltage inside, then outputs a speed command
to a servo amplifier.
(2) Compatible with analog input servo amplifiers
A servo amplifier does not require an extra module to convert pulse input into analog voltage; a standard servo
amplifier can be used.
(3) Servomotor control using a high-resolution encoder
This module handles up to 1Mpulse/s of pulse input from an encoder. Servomotor control that uses high-speed
input pulse signals from a high-resolution encoder improves the accuracy of positioning.
(4) Four types of positioning method
The following control can be executed.
• Position control mode: positioning control and two-phase trapezoidal positioning control
• Speed-position control switch mode: speed-position control switchover and speed control
(5) Zero/gain adjustment through a sequence program
Zero/gain adjustment can be performed through a sequence program. Therefore, the adjustment can be
performed without using a switch or checking a LED, saving man-hour.
(Note that zero/gain adjustment can also be performed using switches on the front of the QD73A1.)
(6) Easy setting with GX works2
Sequence programming is reduced since initial settings and the auto refresh setting can be configured on the
screen. In addition, the setting status and operating status of the module can be checked easily.
