Note) H of FRC means the voltage of 1.5V or more while L means the voltage of 1.0V or less. (At VCC = 5V)
Note) For the Hall input, the input H means the condition in which (+) relative to each phase input (-) is higher by 0.1V.
The input L means the condition in which (+) relative to (-) is lower by 0.1V or more.
Control function & control limiting function
Caution: For the VCRF voltage of control characteristics, the peak value is to be measured.
Cautions for use)
1. Capstan short-brake safety conditions
C_VCC = 14V or less 1500 rpm or less. Limiter 1.1 to 2.6V. 33F or more between C_VCC-C_MGND
2. Capstan direct F/R safety conditions
C_VCC = 16V or less 2500 rpm or less. Limiter 2.6 to 3.0V. 33F or more between C_VCC-C_MGND
