A robot control device includes manual pulse generation units that generate pulses having a pulse number depending on an operation amount of an operator, command signal calculation units that calculate an operation command signal to a robot based on a pulse number to be input, and a pulse number limiting unit that limits, to a threshold, the pulse number to be input into the command signal calculation units, in a case or cases where the pulse number generated by the manual pulse generation units is larger than the predetermined threshold, where, in a case or cases where the pulse number generated by the manual pulse generation units is equal to or less than the threshold, the pulse number is output as it is.
