Compact motion
Based on the Magellan motion processor, the single-axis ION digital drive operates on 12-56 V and 8-15 A (optional heatsink increases current), delivering up to 550 W. The host sends commands such as position, velocity, acceleration, and jerk across the network and generates a trajectory on-the-fly. Profiling modes — S-curve, trapezoidal, velocity contouring, and electronic gearing — are user-selectable. Servo-loop compensation employs a 32-bit position error, PID with velocity and acceleration feedforward, integration limit, and dual biquad filters for complex loads. Other attributes include stall detection and field-oriented and digital-torque control.

Equal input
The pull-type Equalizer eliminates voltage variations and temperature fluctuations by using PWM to change duty cycles. Modulation affects pulse duration, which changes according to data interpreted by the microprocessor. The solenoid operates at ambient temperatures between -40° and 105° C, returns 12 to 25 lbf from a power source of six to 16 V, and enables remote control. Three pins allot wires for battery positive, ground, and a command line. Available in side or flange-mount designs, the Equalizer is customizable to pull-in time duration, force, minimum voltage, thermal shutdown, and current variations.

On display: Equalizer Solenoid
Key feature: Design eliminates external switches, fine winding, and fragile interconnect wiring.
What it means to you: Decreased size: Solenoid, controller (located under end cap and connector shell), and wire harness unite in a single component.
What else: Single-coil winding reduces continuous-operating power by 50%.
