High-precision control of stepper motors:

The technology of the 1-STEP-DRIVE-5A-48V enables highly precise current settings which facilitate fine positioning up to 1/512 step with an absolute error of only ~0.0015°. This corresponds to approx. 102,400 positions per revolution or 0.0035°/step with a 200-step motor.

The module permits connection of a 2-phase stepping motor in the 200 W power range up to 5 A peak with a power supply of 24 to 48 V DC.

Sample function blocks are available for operation with SIMATIC and can be downloaded by the user from the Internet site specified below and then modified.

The 1-STEP-DRIVE-5A-48V provides the following positioning functions:

• Absolute positioning
• Relative positioning
• Reference point approach
• Endless axes: Speed mode/frequency output
• Selection of feedback value

In the manufacturer's manual, you can find a list of possible terminal modules with which the 1-STEP-DRIVE-5A-48V can be operated.
