摘要:
To provide a motor control device, motor control method, and non-transitory computer readable medium recording a motor control program, which add a backlash correction amount to a position command for a motor at the appropriate timing. Included are a first position detection part that detects a first position which is a position of a movable part; a second position detection part that detects a second position which is a position of a driven part; a positional error calculation part that calculates positional error, which is deviation between a converted first position detected value and a second position detected value; and a backlash correction part that adds a backlash correction amount when the absolute value for the variation of the positional error since reversal of a position command was detected exceeds the predetermined reference value.
