BRAKE UNIT FOR PULSE MOTOR

摘要

PURPOSE:To prevent the vibration at the stopping point of a pulse motor by utilizing a memory of ROM or an analog calculating circuit. CONSTITUTION:A value which decides the energizing current of an exciting coil is stored in advace as a digital signal in an ROM49. A multiplexer 48 reads the memory of the ROM49 with the counted value as an address code as the counting of a counter 46 advances. The read output is converted via a D/A converter 50 to an analog signal, and is outputted from a terminal 50a. This output excites the exciting coil corresponding to the incremental stage and performs a suitable braking function.
