Operating Functions
5-2 Speed Control
Function
• Performs Servomotor speed control using analog voltage input from the speed command (REF:
CN1 pins 14 and 15). You can also perform speed control by combining with a controller that has
a position control function.
• You can change the relation between the speed command and the rotation speed by setting the
Speed Command Scale (Pn50).
