I +I VM = (R1 + R 2 + R 3 ) Iref + R1･ M ref K Now that, Iref = Vref / R 2 so that, (Iref ≒100µA setting is appropriate) VM = Vref R R (R1 + 1 + R 2 + R 3 ) + 1 IM Λ Λ (1) R2 K K On the other hand, the voltage applied at the motor itself will be as in the following. VM = E O + RM･IM Λ Λ ( 2) Through (1), (2), and then leading to stabilize the control system. R RM･IM > 1 ･IM K ∴ R1 < K･RM Λ Λ (3) Taking in consideration of deviations, R1(MAX ) < K (MIN)･RM(MIN) with the condition. Items required checking in regard to the temperature coefficient IC items 1. Reference voltage : Temperature coefficient of Vref. 2. Current Ratio : Temperature coefficient of K *1 External component items 3. Temperature coefficient of R1, R2 and R3 The relation among these 3 parts takes the very important roll. 4. Temperature coefficient of motor internal resistance 5. Temperature coefficient of motor generative voltage 6. Temperature coefficient ratio of R1 and RM Count up from 3.4.
