Motor driver built-in 2 axes motor controller


CRUX-D/CRUX-A is a 2 axes stage controller with a built-in micro step 5-phase stepper motor driver.
Low price was actualized comparing to the existing SC series with fewer functions.
Using the handy terminal "INCOM" sold separately, operations such as test run, adjustment, etc. can be performed asily without PC.


[ Features ]

Micro Step Drive with 250 Divisions at Maximum

micro step running driver is equipped as standard.Actualized smooth and low vibration drive, and high precision positioning.
By changing the system parameters for CRUX-D and setting the built-in driver rotary switch for CRUX-A, settings to 16 types and 250
number of divisions at maximum are possible. Also, two rotary switches settings are equipped in CRUX-A, and one can be selected
externally with a division selection signal (D.S).


Switchable Motor Drive Current
For CRUX-D, 0.35A/phase ,0.75A/phase,1.4A/phase can be switched by changing the system parameter. For CRUX-A, the built-in driver rotary switch setting can switch 16 types between 0.35A/phase and 1.48A/phase.


RS-232C, USB2.0 type-B, 2 Types of Communication Ports
CRUX-D/CRUX-A is controlled with a command from host controller (PC, etc.) through the communication port.
Two selectable communication ports, RS-232C and USB, are equipped. Baud rate of RS-232C and USB can be set with the rotary
switch on the rear panel.


* Attached a power supply cable is for using in Japan. Please provide it by customer when a different power supply cable is necessary.(~125V)
