Abstract
A motor drive controller includes: a control circuit unit configured to output a drive control signal for driving a motor in response to a command signal externally input to the control circuit unit; and a motor driving unit configured to output a drive signal to the motor based on the drive control signal output from the control circuit unit. The control circuit unit is provided with: a speed setting unit configured to generate a target rotation speed signal corresponding to a target rotation speed based on a command step determined in response to a step command signal and predetermined setting information when the step command signal is input as the command signal; and a drive control signal generating unit configured to generate and output the drive control signal based on the target rotation speed signal.
