2-3-3 Arrangement and Function of Control Circuit Terminal Block
Analog Monitor output
AM
Multi-function
analog output
(Voltage)
This terminal outputs a signal selected
from the “0 to 10 VDC Voltage Output”
monitor items: Output frequency, Output
current, Output torque (with/without
sign), Output voltage, Input power,
Electronic thermal load rate, LAD
frequency, Motor temperature, and Fin
temperature.
Max. allowable current:
2mA
AMI
Multi-function
analog output
(Current)
This terminal outputs a signal selected
from the “4 to 20 mA DC Current
Output” monitor items: Output
frequency, Output current, Output
torque (without sign), Output voltage,
Input power, Electronic thermal load
rate, LAD frequency, Motor temperature,
and Fin temperature.
Allowable load
impedance: 250 Ω max.
Digital
(contact)
Monitor output MP
Multi-function
digital output
This terminal outputs a signal selected
from the “0 to 10 VDC Voltage Output
(PWM)” monitor items: Output
frequency, Output current, Output
torque (without sign), Output voltage,
Input power, Electronic thermal load
rate, LAD frequency, Motor temperature,
Fin temperature, Digital output
frequency, and Digital current monitor.
“Digital output frequency” and “Digital
current monitor” output a frequency at a
pulse of 0/10 VDC pulse voltage and
with a duty ratio of 50%.
Max. allowable current:
1.2 mA
Max. frequency: 3.6 kHz
Power supply
P24
Internal 24
VDC
24-VDC power supply for contact input
signal.
When the source logic is selected, this
terminal functions as the contact input
common terminal.
Max. allowable output
current: 100 mA
SC
Sequence
input
common
Common terminal for the interface
power supply terminal P24, thermistor
input terminal TH , and digital monitor
terminal MP.
When the sink logic is selected, this
terminal functions as the contact input
common terminal.
Do not connect this terminal to the
ground.
