All essential components of the stepper motor with controller are in one housing. This makes the entire structure more compact and requires less space.
Simple installation
The integration of the components eliminates the need to install and wire separate drivers and controllers, which simplifies and speeds up installation and setup.
Less cabling required
Less cabling means greater reliability and less susceptibility to faults. It also reduces the electromagnetic interference (EMI) that can be caused by long cable runs.
Built-in intelligence
Advanced functions such as microstepping, torque control, speed control and fault diagnostics are integrated.
Cost savings
Integration can also reduce overall costs as fewer separate components need to be purchased and assembled.
Simplified maintenance
With fewer separate components, maintenance is often easier as there are fewer potential sources of faults and problems can be diagnosed more quickly.
