UIM42-a and UIM42-b stepper motors could use a UIM24002 stepper motor driver to building up an integrated stepper motor
UIM42-c stepper motor could use a UIM24002 or a UIM24004 stepper motor driver for an integrated stepper motor
UIM42-d stepper motor is corresponding to a UIM24004 stepper motor driver
You have to consider at least two parameters of a stepper motor to choose the right UIM stepper motor driver for an integrated stepper motor: the Rated Current and the Torque
UIM24002 adopt 10-35V DC power supply and supply 0-2 amps settable output current.
UIM24004 adopt 12-40V DC power supply and supply 1.5-4 amps adjustable output current.
The UIM24004 performs much better than UIM24002, the temperature of UIM24004 after a 8 hours continuous working is about 50 degree Celsius and the UIM24002 could reach about 60 degree Celsius which is among their working environment. The working condition influence a bit on the temperature of the stepper motor driver: if there is a big metal module on your machine for mounting the stepper motor or working with pause, the temperature of the integrated stepper motor will go down.
Besides this Parallel port stepper driver, you could also use UIM241 Serial port with RS232 interface and UIM242 CANBus networking stepper controllers to build up an integrated stepper motor.
