Functional Descriptions (By Parameter No.)

Used to set the control functions of SW1, SW2 and SW3 (control circuit terminal Nos. 14, 15 and 16) when set as the multi-step speed with parameter No. 20

Data setting value	Function details
0	Set to multi-step speed frequency operation
1	Set to 2nd, 3rd and 4th acceleration/deceleration operation function
2	Set to acceleration/deceleration linked multi-step speed frequency operation function

(When parameter No.20 is set to "0" multi-step speed frequency operation)

Notes) 1. Speed 1 will be the command value of the frequency setting signal set with parameter No. 9.

2. The Speed 2 to 8 frequencies are set with parameter Nos. 30 to 36, and the 2nd to 4th acceleration/deceleration times are set with parameter Nos. 37 to 42.
