Chapter 6. Function Description (I/O)
4) I/O_10 Inversion of Multi-function aux contact output (Relay output, Open collector output)
Factory default settinf of Multi-function Relay outputs is A contact. To change it to B contact, set it to “1”.
See the below for setting example: (terminal layout is AX1, AX2, OC1, NC, NC from left.)
(Setting example)
(AX1 ~ OC1: A contact) (AX1, OC1: B contact)
6.2.3 Multi-function analog input
1) I/O_11 ~ 25(Definition of Multi-function analog input terminal, Gain, Bias, LPF time constant)
3 analog inputs are assigned for IO board. Ai3 serves as the Motor NTC input port and voltage or current signal can
be fed into Ai1 and Ai2 by the jumper setting. Analog input on the control circuit terminal can be used as single function
among the following 8 functions on the table shown below (9 functions for Ai3). Voltage input range is –10 ~ +10V and
current input range is 4~20mA. Any analog input cannot be set as the same function as the other inputs. If 2 analog
inputs are set to the same function, last set analog input is changed to ’Not Used’. In case analog input is changed to
the other function, previously set value is initialized to 0.

Thermal sensor in the motor is fed into this terminal. In this case,
the motor temperature is displayed and motor overheat alarm
and trip signal can be triggered.
