(‡) The accurate control of this parameter (Limmax=0.1deg, HROT=25kA/m) takes place by means of sample tests
A: Output characteristic definitions
∆VO1/VCC1 = (VOMAX1 – VOMIN1)/VCC1 or/ ∆VO2/VCC2 = (VOMAX2 – VOMIN2)/VCC2
VOFF1/VCC1 = ½(VOMAX1 + VOMIN1)/VCC1 or/ VOFF2/VCC2 = ½(VOMAX2 + VOMIN2)/VCC2
∆αH = MAX | αLEFT TURN – αRIGHT TURN |
∆α = MAX | αo – α |
(max. angular difference between left and right turn)
(max. angular difference between actual value αoand measured angle,
without offset error)
