A method is provided for adjusting the setup of a handling machine, by a handling machine operator. The method includes the handling machine operator moving a control member in order to set a maximum speed of operation of said actuator or motor. A maximum speed setting made in the prior step is stored in a suitable memory integrated into a computer of a control station of the handling machine. The control station adjusts a work output of the handling machine to operate within the parameters of control law, the adjustment including the handing machine not exceeding the stored maximum operating speed or speeds.

A machine tool controlled by a numerical controller includes a feed handle for driving a drive-shaft for moving a tool and a workpiece relatively by using a mechanical mechanism and a motor for driving the drive shaft. The numerical controller generates an automatic feed command for driving the motor when a specific handle operation performed on the feed handle is detected.

A method is provided for adjusting a handling machine (1) involves moving a control member (2) for controlling an actuator (7) or a motor (11) to adjust a maximum operating speed of the actuator (7) or motor (11) tool. The method includes memorizing a maximum speed setting in a suitable memory (4), and subjecting the work of the handling machine (1) to a control law, not exceeding the memorized maximum speed of operation. The method is applied of the adjustment method to a handling machine (1) including a plurality of actuators (7, 9, 11, 13, 15) and at least one actuator control member (2, 3).

A control unit includes a position command generation unit generating a position command, a position control unit outputting a first speed command such that detected position tracks the position command, a pressure command generation unit generating a pressure command, a pressure control unit outputting a second speed command such that detected pressure or force tracks the pressure command, a speed command selection unit selecting creep speed, the first speed command, or the second speed command and outputs it as a speed command for the motor to operate; and a speed control unit outputting a current command for supplying current to the motor such that the motor speed tracks the speed command output by the speed command selection unit. After selecting the first speed command, the speed command selection unit selects the second speed command or the creep speed at timing when the first speed command falls below the creep speed.
