Overview
Overview
Introduction
Setter characteristics, features and part names are described in this sec-
tion.
Introduction
Operating principle
An Iwaki ST-900N stroke setter is designed for use with the Iwaki AX metering pumps with a servo unit. The
setter controls the stroke length of the AX pumps in proportion to 4-20mADC or 1-5VDC signal from user's
controller (proportional control).
Principle of operation
The ST setter monitors pump stroke length via the feedback signal (signal voltage from the potentiometer) and
adjusts to a target length by controlling the servo motor (feedback control).
Features
● Manual control (stroke length)
Keypad operation changes the stroke length of the pump in between 0 and 100%.
● Auto control (stroke length)
The ST setter controls a stroke length in proportion to 4-20mA(/1-5VDC) signal from user's controller and the
operation programming.
● Remote control
"Local control (default)" is changed to "Remote control (AUTO mode with keypad locked)" while a no-voltage
contact signal or open collector signal is inputted to the terminal pin 8(plus) & 9(minus).
● Multivoltage operation
The ST setter is a multivoltage type (100-240VAC) and can be selected without concern for local power voltage.

Operational functions
Manual mode
■ Real-time SL adjustment
Use the UP and DOWN keys to change a stroke length in operation (MAN mode). Stroke length changes only
while either key is pressed. The "INC" LED lights when the stroke length extends and the "DEC" LED lights
when the stroke length retracts. This adjustment is the factory default setting.
■ Target SL setting
Use the UP and DOWN keys to set and the SET/ENT key to enter a target stroke length in operation (MAN
mode). The ST setter starts to control the servo motor to meet the target length. See page 33 for selecting this
method.
Auto mode
The pump extends/shortens the stroke length in the range of 0-100% in proportion to 4-20mA or 1-5VDC from
user controller. See page 37 for detail. A proportional line can be programmed by proportional band setting,
Current-Stroke setting or upper/lower limit setting as necessary.
