An example of operation for Pn000 = n.
5
(Switching between internal set speed control
and position control) is given below. This example combines speed control with the internal set
speeds with the soft start function. The shock that results from speed changes is reduced by
using the soft start function.
Note: 1. Set t1 so that it is greater than 2 ms. The value of t1 is not affected by whether the soft start function is
used.
2. A maximum delay of 2 ms occurs in reading the /SPD-A and /SPD-B signals.
3. The speed is decelerated with the deceleration time set in Pn306 (Soft Start Deceleration Time), and inter-
nal set speed control is changed to position control after the Servomotor comes to a stop.
The pulse train reference is received after the switch to position control. Always wait until after position
control is started before you input the pulse train reference from the host computer. After position control is
started, the /COIN (Positioning Completion) signal is output. Use the /COIN signal to confirm that the con-
trol method has changed.
