A speed regulator for a guide and follower motor assembly. A guide pulse frequency generator driven by a guide motor drives a frequency converter which drives a follower motor. The frequency converter includes a frequency regulator with a negative feed back which includes a frequency divider. Adjusting and setting circuits for the frequency divider include an up/down counter for operating the frequency divider, a resetting operation of the counter to provide a frequency indicating value for its output, an adjustable pulse generator for driving the counter, an add/subtract circuit, and a comparator responsive to the add/subtract circuit and the counter to control the pulse generator. |
