ZonicBook/618E eZ-TOMAS Software Key Phaser: Input Channel Configuration and discussion. Mike Grace
eZ-TOMAS: Tach Configuration and Discussion Select Analysis Frequency Based on ~70 samples per revolution at max. machine speed (CPS). For example, 3600 RPM = 60 CPS 60 CPS * 70 samples / revolution = 4200 samples per second. Recommend Analysis Frequency = 2000 Hz. (sample rate would be 5120 samples per second … 2.56 * Fmax)
eZ-TOMAS: Tach Configuration and Discussion Input Channels: 2 options for ZonicBook Hardware. Tach Inputs: TTL Pulses, Laser Tachs, Optical Tachs, Mag Pickups. Select AC Coupling. Select Counter Mode for 1 pulse per revolution, Select Period Mode for Multiple pulses per revolution.
eZ-TOMAS: Tach Configuration and Discussion Input Channels: 2 options for ZonicBook Hardware. Analog Inputs: TTL Pulses, Laser Tachs, Optical Tachs, Mag Pickups, key phaser. Select either AC or DC Coupling. Trigger Direction / Voltage: Positive and + 1 V (typical) for laser and photo-eye Negative and -1 V (typical) for key phaser.
