Stepper motor control (C230-2, C240)
In addition to the analog setpoint outputs, the C230-2/C240 has pulse outputs for up to four
stepper motor axes. The stepper motor is controlled by means of cycle clocks, the number of
which determines the position and the frequency of which determines the rotational speed
(velocity). The actual position value is not measured during controlled operation; the position
controller takes the number of pulses output (position setpoint) as the actual value. With this
type of control circuit, the motor cannot lose any steps in order to enable exact positioning.
