Key Features
- Four motor speed drive control models ranging from a simple speed dial/display to complex machine/process synchronizers
- Capable of many motor/machine control schemes, from open-loop master to closed-loop pulse-locked speed/event synchronized follower
- Compatible with all motor speed drives of any size/power rating with an analog input (AC, AC Vector, DC and Servo)
Products
Motor speed control potentiometers with a programmable LCD display for the speed setting or measured shaft speed. The LCD displays four digits in user units. Accu-Tach works with pulse-frequency output shaft speed sensors and incremental shaft encoders.
Closed-loop motor speed drive control. Master and Ratio-Follower modes and programmable input functions. Options include analog speed feedback input, analog setpoint inputs and relay outputs. Works with incremental shaft encoders and pulse-frequency output shaft speed sensors.
Closed-loop synchronous motor speed drive control. Modes include zero-cumulative-error Ratio-Follower (electronic gearing) and zero-cumulative-error Index-Follower (mechanical event/phase synchronization). Features include Forward-only and Forward/Reverse settings for uni/bi-directional control, multiple setpoints and many programmable contact-closure input and NPN output functions. Builds numerous machine synchronizing/follower processes. Works with quadrature incremental shaft encoders (all modes) and prox, photo-eye and other presence/event sensors (Index-Follower mode).
