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

"maximum frequency" (Hz)
Setting of the frequency as each speed
Carefully note that during multispeed operation, the rotation direction specified in an operation command is
reversed if the sum of the frequencies specified by the main frequency and auxiliary frequency commands
is less than 0 Hz when the following settings have been made:
- The control circuit terminal block (01) is specified for the frequency source setting (A001).
- The external analog input (O/O2/OI) mode, set by a combination of [AT] selection (A005), [O2] selection
(A006), and AT terminal On/Off state allows reversible motor operation.
C011 to C018: Terminal [1] to [8] active state
C019: Terminal [FW] active state
