5-2 Speed Control

Outline of Operation

Motor speed control is performed based on the analog voltage input from the controller.
You can also perform position 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 (Pn302).

direction for the speed command.
Set the input gain for the analog speed command input.
Set the gain of conversion from applied voltage to the analog
speed command (REF) to motor command speed.
Set the acceleration time for internally set speed control. Set
the time until 1,000 r/min is reached.
Set the deceleration time for internally set speed control. Set
the time until 1,000 r/min is reached.
