Compact stepper drive

The Plus-B series of stepper motor drives is suitable for high-power single- and dual-axis motion control applications where high speed and resolution are required. They are AC powered and require only a mains transformer and a suitable controller with step and direction output signals. The opto-isolated step and direction inputs are compatible with 5 or 12 V voltage sourcing or current sinking indexers. A built-in ramped oscillator is useful for manual control.

Two models are available, the Plus-B3 for lower voltage, higher current applications and the Plus-B4 for higher voltage to cover large motors or high speeds. Protection against motor short circuit and incorrect power supply voltage are also included. The maximum input frequency is 60 kHz, so for rapid moves there is a X4 input frequency multiplier built into the drive. The small size enables large numbers of drives to be packed into a small cabinet.
