More Information

Overview Manuals Current Control Motion Stall Detection Application
  • Controls four two-phase bipolar stepper motors
  • Provides 256 microsteps with independent current profiles
  • Integrates stall detection and ramp motion into Automation Studio

X67SM4320 is a B&R 4-axis stepper motor module designed for the X67 System.

The module places four compact stepper axes directly on the machine and executes ramp-based DS402-style motion functions through the X67 station.

Before installation or replacement, verify the complete material number, the 24 VDC motor supply, 1 A nominal and 1.5 A peak current, 6 A module limit, motor winding and connector pinout, current profiles, stall threshold, motion project, recovery time and IP67 sealing.

Availability, condition, price, and shipping time for X67SM4320 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can B&R X67SM4320 run four motors at 1.5 A continuously?
No. The 1.5 A value is a two-second peak after at least ten seconds of recovery at no more than 1 A, and total module current is limited to 6 A.
How should a motor be matched to B&R X67SM4320?
Confirm a two-phase bipolar winding, 24 VDC system, winding current, inductance, connector pinout, cable and the required speed-torque curve before commissioning.
Why can B&R X67SM4320 report a stall when the axis still moves?
Review the configured threshold, acceleration, load variation, supply drop, current profile, resonance, mechanical friction, motor sizing and cable connection.
What is the benefit of separate holding current on B&R X67SM4320?
Reducing holding current can lower motor heating and energy use while retaining enough stationary torque; validate the value against the real load.
Can B&R X67SM4320 be used as a safety motion controller?
No. Its motion functions and stall detection do not replace a certified safety architecture for safe stop or safe motion.
What should be saved before replacing B&R X67SM4320?
Save motor parameters, current profiles, ramp settings, stall thresholds, homing and position configuration, connector labels, X2X position and diagnostics.
What is required to retain IP67 protection on B&R X67SM4320?
Use compatible sealed M8 and A-coded or B-coded M12 connectors as applicable, cap unused ports and inspect torque, seals, housing and cables.
