CAUTION

1.The multi-speed settings override the main speeds (across terminals 2-5, 4-5, setting dial). When the multi-speed settings and setting dial are used in the combined operation mode (Pr. 79=3), the multi-speed settings have precedence.

2.The multi-speeds can also be set in the PU or external operation mode.

3.For 3-speed setting, if two or three speeds are simultaneously selected, priority is given to the frequency setting of the lower signal.

4.Pr. 24 to Pr. 27 and Pr. 80 to Pr. 87 settings have no priority between them.

5.The parameter values can be changed during operation.

6.When using this function with the jog signal, the jog signal has precedence.

REMARKS

* When terminal assignment is changed using Pr. 60 to Pr. 63, the other functions may be affected. Check the functions of the corresponding terminals before making setting.

The frequency-set external terminals have the following priority: Jog > multi-speed operation > AU (terminal 4) > terminal 2
