Terminal for inverter chassis
+10VDC power supply for setting potentiometer (POT: 1 to 5kΩ)
0 to +10VDC/0to 100% (0 to +VDC/0 to 100%)
Used for PID control reference signal or feedback signal
4 to 20mA DC/0 to 100%
Used for PID control feedback signal or reference signal
Common for analog signals
FWD – ON ........ The motor runs in the forward direction
FWD – OFF ...... The motor decelerates and stops
REV – ON ........ The motor runs in the reverse direction
REV – OFF ...... The motor decelerates and stops
These terminals can be preset as follows
(SS1):
0, 1 different frequencies can be selectable
(SS1, SS2): 0 to 3 different frequencies can be selectable
(BX) – ON ...... Motor will coast-to-stop
(No alarm signal will be output)
(RST) – ON ...... Faults are reset
(This signal should be held for more than 0.1s)
(THR) – OFF ...... "0H2 trip" occur and motor will coast-to-stop
(WE-KP) – ON ...... The data will be changed by KEYPAD panel
(Hz/PID) – ON ...... The PID control is cancelled and KEYPAD panel frequency
setting (
or
(LE) – ON ...... The link operation is effective
DC voltage supply (+24V, max 100mA)
Common for digital signal
• Output voltage (0 to 10VDC) is proportional to selected function's value as follows
. Output frequency (0 to max. frequency)
. Output current (0 to 200%)
. PID feedback value (0 to 100%)
. DC link circuit voltage
• Bias value can be preset

Remarks
Allowable maximum output currrent: 10mA
• Input impedance: 22kΩ
• Allowable maximum input voltage: 50mA
• If input voltage is 10 to 15VDC, then the inverter
clamps it at 10VDC
• Input impedance: 250Ω
• Allowable maximum input current: 30mA DC
• If input voltage is 20 to 30mA DC, then the
inverter clamps it at 20mA DC
Same potential as CM – 0V
When FWD and REV are simultaneously ON, the
motor decelerates and stops
When FWD and REV are simultaneously ON, the
motor decelerates and stops
• Sink type terminal specifications
• ON state maximum input voltage: 2V
(maximum source current: 6mA)
• OFF state maximum terminal voltage: 24 to 27V
(allowable maximum leakage current: 0.5mA)
0 frequency (All (SS1) and (SS2) signals are OFF)
is set by "F01"
• The motor restarts from 0Hz by turning off BX
with the operation command (FWD or REV) ON
• Assigned to terminal X2 at factory setting
• During normal operating, this signal is ignored
• Assigned to terminal X3 at factory setting
This alarm signal is held internally
For switch link operation to communication
DIPSW select: SW7
Same potential as 11
Allowable maximum output currrent: 2mA
Contact rating:
• 250V AC, 0.3A, cos ø=0.3
• 48VDC, 0.5A, non-inductive
