Abstract
A motor translator with an up/down counter which inputs a preprogrammed read-only memory for selectively driving a multiple phase stepping motor. The read-only memory stores data at preselected locations and generates drive signals in a sequence which corresponds to the coil switching sequence of the stepping motor. The drive signals generated by the read-only memory in response to direction signals received from the up/down counter are applied to the motor for selective energization thereof.
Claims1
In combination with a multiple coil motor, a device for controlling the motor, said device comprising:
- (a) means for generating command signals;
- (b) input means for receiving said command signals,
- (c) an up/down binary coded decimal counter connected to said input means for receiving said command signals and generating direction signals;
- and
- (d) a read-only memory connected to said counter for receiving said direction signals and for generating drive signals for controlling the motor, said read-only memory storing data representing a coil switching sequence of the motor.
