2.5.5 Control terminal wiring
Functions of control terminals are listed in Table 2.8. Control terminal connection methods are differ-
ent due to different function parameter settings in line with use purpose of the inverter.
Perform wiring properly to reduce the noise caused by the main circuit wiring.
Note: Connect terminals T1 and R1 in the output side of earth leakage circuit breaker when turning
the power ON. Earth leakage circuit breaker will malfunction if the terminals are connected in the
input side for the input of the inverter is a three-phase and the terminals R1 and T1 are single-
phases. Be sure to connect the terminals R1 and T1 from the input side to auxiliary B contact of insu-
lation transformer or magnetic contactor in compliance with the location shown in the figure below.
Functions
Power for external frequency setting (DC +10 V)
(1) Analog voltage inputs the command value for frequency setting
DC0~±10V/0~±100 (%)(positive running)
，
DC±10~0V/0~100 (%)
(reverse running)
(2) Analog input for the PID instruction, PID control feedback
signal, the frequency auxiliary setting, ratio setting, torque limit
setting, and analog input monitor allocation.
(3) Hardware Specifications
* Input Impedance: 22 (kΩ)
* The maximum possible input DC ± 15V. Apply DC ± 10V when it
exceeds DC ± 10V.
* set the function parameter 02.35 as "0" when inputting the analog
voltage of positive and negative (DC0 ~ ± 10V) via terminal AVI
