KNF stepping motor controller:
Stepping motor partial stroke FE Z5 Dispense partial stroke controller, partial stroke metering using potentiometer or analogue signals possible, alarm output etc.
Especially in the development phase it is useful to try different options out without investing a lot of time programming. Therefore, we offer a flexible controller which can be adapted for many different applications.
.PWR supply voltage 10 … 28 V DC
.2 phase stepper motor controller
.Motor speed control using a potentiometer
.Motor speed control with an analog signal 0-10V / 4-20mA
.Interface for the Hall sensor
.Customized programming for fast suction / reduced pulsation / partial strokes
.Impulse input – 1 impulse = 1 micro step
.Emergency stop - 1 impulse stops the power supply to the motor
