Stepper Drivers
If ordered separately the stepper drivers will not be mounted to the pump.
Available to purchase online via BOX-it (see order information below).
Pico 1.4 Miniature Stepper Driver, with Advanced Features
The Pico 1.4 is a miniature stepper driver recommended for the 9K, 9QQ and 9QX series. Designed specificically as a peristaltic pump driver it includes 1/256 mirco stepping for extremely smooth rotation, reduction of noise and the unique ability to drive the pump with individual pulses. Each pulse provided by an external signal rotates the pump by a single micro-step, therefore providing control of the speed / flow at the highest possible resolution. Alternatively speed control is available with a traditional 0 to 5.0 V DC or 0 to 100% PWM input.
Features include:
› 0 to 5.0 V or 0 to 100% PWM speed control
› indivudual micro-step speed control
› 1/256 micro stepping (or 1/16)
› mounts directly on 9K, 9QQ and 9QX peristaltic pumps
› 2 speed ranges
› direction and enable inputs
› convenient 5.0 V DC output for simple speed control via an external potentiometer
See PDF datasheet for full connection and control details.
Note: 5 V DC (Output) is supplied insulated. Damage will occur if connected to any voltage or GND.

Digital Stepper Driver - programmable
The Boxer digital stepper driver (iD) is a power and fully programmable controller designed specifically for use with the peristaltic pump series 25K, 15KS, 15QQ, 6K, 6KP, 9K, 9QQ and 9QX.
Features include:
› 3 Running modes (dispense, dose and analogue)
› LCD display
› Calibration for volumetric dispense
› Automatic stall and open lid detection (for 25K series only)
› Push button or remote inputs
› Programmable settings include acceleration, deceleration, time interval and suck-back.
When ordered with the 25K, 15KSand 15QQ the iD driver is neatly mounted on the back of the motor.

Analogue Stepper Driver - for external speed pot or direct voltage input
Available as 2 or 4 amp drivers:
A2 Driver: 2 amp, recommended for 9K, 9QQ, 9QX, and 15KS with Nema 17 motor and 15QQ with Nema 17 motor
A4 Driver: 4 amp, recommended for 15KS with Nema 23 motor, 15QQ with Nema 23 motor, 25K, 6K and 6KP
Can be used with an external potentiometer (left) or 0 to 5 V speed control signal applied directly to pin 8 (right).
Wiring to motor:
A+ = black
A- = green
B- = red
B+ = blue
Pin 8 (SPD, speed control) can be varied between 0 to 5 V DC.
High speed mode: 0 to 5 V DC = 0 to1900 rpm
Low speed mode: 0 to 5 V DC = 0 to 150 rpm
Additional speed ranges are available by altering the jumpers on the reverse of the driver. See datasheet for details.
Pins 3, 4, 5 and 6 are internally pulled up (with no connection to ground the driver enabled, on and in high speed mode).
Stop (pin 4 to GND) will lock the rotor with energised coils. Disable (pin 3 to GND) will switch off the coil outputs and the rotor can rotate freely.
Always start at low rpm and increase to find max speed (stall point of motor).
To avoid high motor surface temperatures at slow speed operation the current should be limited. See datasheet for details.
