Stepper Motor Controller M-module with Amplifiers – M321
The M321 Stepper Motor Controller with onboard amplifiers is an ideal solution for all applications where stepper motors must be controlled with a maximum of flexibility and a minimum of overhead. The local MC68332 Microcontroller handles commands passed on from the host CPU and takes care of controlling the onboard power amplifiers to drive either two 2-phase motors (independent) or one 4-phase motor. The amplifiers are bi-polar driving circuits in constant current driving mode. Amplifiers are over-current and thermal protected.
Full-, half- and microstepping capability is provided by the local firmware. Up to 16 microsteps per full step can be made.
Two optical isolated home-inputs provide means for feedback on home position.
