4.2.40 Input terminal a/b (NO/NC) selection<br />
The input terminal a/b (NO/NC) selection function allows you to<br />
specify a-contact or b-contact input for each of the intelligent<br />
input terminals [1] to [8] and the FW terminal.<br />
An a-contact turns on the input signal when closed and turns it off when opened.<br />
An b-contact turns on the input signal when opened and turns it off when closed.<br />
The terminal to which the reset (RS) function is assigned functions only as an a-contact.<br />
Item Function code Data Description<br />
Terminal active state C011 to C018<br />
00 a-contact (NO)<br />
01 b-contact (NC)<br />
Terminal [FW] active state C019<br />
00 a-contact (NO)<br />
01 b-contact (NC)<br />
4.2.41 Multispeed select setting (CF1 to CF4 and SF1 to SF7)<br />
The multispeed select setting function allows you to set multiple<br />
motor speeds and switch among them by way of signal input<br />
via specified terminals.<br />
Multispeed operation can be performed in two modes: binary<br />
operation mode (with up to 16 speeds) using four input<br />
terminals and bit operation mode (with up to eight speeds)<br />
using seven input terminals.<br />

A021 to A035<br />
Carefully note that during multispeed operation, the rotation direction specified in an operation command is<br />
reversed if the sum of the frequencies specified by the main frequency and auxiliary frequency commands<br />
is less than 0 Hz when the following settings have been made:<br />
- The control circuit terminal block (01) is specified for the frequency source setting (A001).<br />
- The external analog input (O/O2/OI) mode, set by a combination of [AT] selection (A005), [O2] selection<br />
(A006), and AT terminal On/Off state allows reversible motor operation.<br />
