NOTE 1 The following feedrate error can occur:
Gear Motor Axis (b) Speed command Amplifier Detector (a)
(a) With the speed command based on PMC axis control, a servo motor speed is specified as a feedrate. So, in order to command a feedrate for an axis (b) The minimum unit of feedrate is given by the expression below. An integer must be specified. No finer value may be specified. ÷ 1000 (mm/min) A calculation is made according to IS-B. × P ÷ 1000 (mm/min) A calculation is made according to IS-B. -1 ) P : Number of pulses per revolution of a detector for speed feedback 2 In the speed command mode, a speed after acceleration/deceleration is command for the servo control section. At this time, a position control loop gain 3 Machine lock is disabled for the speed command.
