ELECTRICAL DATA Version Supply voltage (Up) Max. supply current (without load) Light source Incremental signals Two sinusoidal I., and l2 Amplitude at 1 kQ load: -\, = 7..A6\jA -I2 = 7...16|jA Differential sine +A/-A and +B/-B Amplitude at 120 Q load: - A = 0.6...1.2 V - B = 0.6...1.2 V Differential square-wave U1/U1 and U2/U2. Signal levels at 20 mA load current: - low (logic "0") < 0.5 V - high (logic " 1") > 2.4 V Reference signal Photoelectric angle encoder A90H is a high end incremental encoder that produces up to 1.800.000 output pulses per revolution. It has hollow shaft, integrated stator coupling and the accuracy of up to ±5 arc. sec. and is available in two different mounting types coupling via shaft collar or via central screw. One quasi-triangular +R and its complementary -R per revolution. Signals magnitude at 120Q load - R = 0.2...0.8 V (usable component) One differential square-wave U0/U0 per revolution. Signal levels at 20 mA load current: - low (logic "0") < 0.5 V - high (logic " 1") > 2.4 V Fault detection signal Us* - no error occur - error occur one square-wave pulse high low one square-wave pulse high low 160-2000 kHz (depends on interpolation factor) Maximum rise and fall time Standard cable length I lags I for clockwise rotation (viewed from encoder mounting side) +B lags +A for clockwise rotation (viewed from encoder mounting side) U2 lags U1 with clockwise rotation (viewed from encoder mounting side) Maximum cable length 5 m Output signals MOUNTING TYPE H (SCREW] MOUNTING TYPE P CCLAMP] MOUNTING TYPE P (CLAMP) MOUNTING TYPE H (SCREW) For highest quality up-to-date drawings please refer to our website www.precizika.com MECHANICAL DATA Line number on disc (z) Number of output pulses per revolution for A90H-F Reference signal: - standard (S) - distance-coded (K) one per shaft revolution 36 per shaft revolution Permissible mech. speed < 3000 rp Max. operating speed (depends on num- 600 to 1000 rpm ber of output pulses) Accuracy grades ±5.0 arc. sec Permissible shaft run out: - axial - radial Rotor moment of inertia Protection (IEC 529) Maximum weight without cable Operating temperature Storage temperature Maximum humidity (non condensing) Permissible vibration (55 to 2000 Hz) Permissible shock (5 ms) ORDER FORM ANGLE ENCODERS - A90H *only F signal version for >18000 pulses P - clamp S - version S H - screw (cable outlet) C-version C (connector outlet) DIGITAL READOUT DEVICES D9 - flat, 9 pins D15 - flat, 15 pins RS10 - round, 10 pins ONC - round, 10 pins EXTERNAL INTERPOLATOR
