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
Terminal active state	C011 to C018	00	a-contact (NO)
		01	b-contact (NC)
Terminal [FW] active state	C019	00	a-contact (NO)
		01	b-contact (NC)

4.2.40 Multispeed select setting (CF1 to CF4 and SF1 to SF7) Related code

The multispeed select setting function allows you to set multiple				A019: Multispeed operation selection
motor speeds and switch among them by way of signal input				A020/A220/A320: Multispeed frequency
via specified terminals.				setting, 1st/2nd/3rd motors
Multispeed operation can be performed in two modes: binary				A021 to A035: Multispeed 1 to 15 settings
				C001 to C008: Terminal [1] to [8] functions
operation mode (with up to 16 speeds) using four input				C169: Multistage speed/position determination
terminals and bit operation mode (with up to eight speeds)				time
using seven input terminals.
Item		Function code	Data	Description
Multispeed		A019	00	Binary operation mode with up to 16 speeds
operation selection			01	Bit operation mode with up to 8 speeds
Multispeed 0	to 15	A020/A220/	0.00 or "start frequency" to
		A320		Setting of the frequency as each speed
settings			"maximum frequency" (Hz)
		A021 to A035

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.
