1. System Safety
CAUTION : To prevent power surge and damage to the board, apply and remove power by the AC source of the power supply. DO NOT PLUG AND UNPLUG AT THE BOARD.
CAUTION : To insure proper operation of the board be sure all wiring and connections are correct and secure.
CAUTION : Keep fluids away from the electronics.
CAUTION : To prevent heat buildup in the motor, current to the motor should be reduced to holding current or turned off between cycles.
2. System Description
The “ICST” is a programmable step motor control intended for use with FMI step motor equipped pumps and dispensers. Using a computer programming adapter and exclusive ICSTPLE (program loader and editor) CD for Windows®, the operator can program the pump / dispenser protocol that fits his application.
2.1 Functions
Fluid Metering Inc. can supply custom programs for the driver to fit most expected conditions. Listed are a few of the functions of the driver boards programming.
Run: Clockwise or counter clockwise at fixed rate or through a profile table. The motor can be accelerated and decelerated through a variable number of steps.
Stop: Stop can be programmed to actuate on either the leading or the trailing edge of the pumps rotational flag. The stop can be also set to go any number of steps past the trip point. For example if the program is set to stop on the trailing edge of the flag, going clockwise this would stop the pump ½ way into the discharge stroke, the program can be instructed to go 100 steps past the flag sense and stop at the bottom of the discharge stroke; without interrupting the rotation. FMI standard (best) stop point is ½ way into the inlet stroke
Flow control: Program flow control includes the following; call, if, else, loop, goto, set, clear, waitfor, repeat, run, halt, stop.
2.2 Features
Designed for maximum performance when mated to FMI 23 and 17 frame 1.8º step motors. Most FMI step motor pumps come standard with a sensor and rotational flag that is aligned to the pump piston. The rotational flag sensor outputs motor and or piston position to the driver.
All external connections to the driver board are via standard Waldom/Molex straight headers, except the power input witch is a standard modular DC center positive receptacle. Development kit has connections via barrier terminal blocks, except power input.
MOTOR OUTPUT POWER: Has three states, full power (1 Amp/Phase), low power (300 ma/Phase), or off. Power settings can be programmed to any state at any time. Ratings are ± 10%.

ACCESSORY OUTPUTS: Two dedicated power level outputs rated at supply voltage (24VDC) and 150 milliamps each are available to drive external solenoids or relays.
TTL LEVEL INPUTS: Two dedicated TTL compatible high impedance, single ended, nonisolated, ground referenced, 5V inputs are provided. One is for Fluid Metering Inc. 5-wire optical sensor. The other is high speed input capable recognizing an input pulse with a duration as little as 4 Microseconds.
TTL LEVEL CONTROL: Seven TTL compatible I/O lines are available. These lines are current limited to 5 milliamps each. All I/O lines are fully programmable.
3. System Installation
CAUTION : To insure proper operation of the board be sure all wiring and connections are correct and secure.
The “ICST” is a bi-polar driver only, set up to work half stepping only. For a standard FMI 1.8º stepping motor, this equals 400 steps per revolution. Speed and rotational calculations need to be made from the 400 steps per revolution.
Stepping motors are made with different numbers of leads, there are 4, 6 and 8 lead motors. The 23 frame motor used on our general product line is an (8) eight lead motor. This motor, for the best performance, works most efficiently when wired bipolar–series. The 17 frame motor is a (6) six lead, and works most efficiently when wired half coil.

FMI Sensor (STD. Optical Sensor) P/N 110569
This is a 5 lead inverted open collector output sensor. Signal goes high when the light source is blocked. The pull-up and load resistors are built into the driver, so that the sensor can be directly wired to the driver board.
RED wire is + V for the Ired LED.
BLACK wire is the ground for the Ired LED.
WHITE wire is the + V for the output.
GREEN wire is the ground for the output.
BLUE wire is the inverted open collector output to the controller.
