MAIN
CIRCUIT:
L3
AC Supply Line
Input Terminals
Connection for commercial power VAC 60 Hz) or
(380-460 VAC 50 Hz).
lnverter Output
Terminals
Connection for induction motor.
Brake
Unit Terminals Connection for brake unit (optional). (Brake resistor must be
connected through brake unit.)
To be connected when power factor improving DC Reactor
(optional on 75 HP and below) is used. (Provided and required on
100 HP and above.)
P, DC Reactor
Connection Terminals
Ground Terminal Connection for ground.
CONTROL
POWER:
RO, TO Control Power
Auxiliary Input Connection for single-phase AC power for backing up the
control circuit power when input starter is used (460 VAC).
FREQ. SET
MONITOR
11 Frequency Setting
Common Common terminal for frequency setting signals (terminals
12, 13, and Cl). (Speed Pot Common)
12 Frequency Setting
Voltage Input
When 0 to + VDC is input, the maximum frequency is
reached at 0 VDC. The output frequency is proportional
down to 0 VDC. Input impedance is 22K ohm. (Speed Pot Wiper)
13 Frequency Setting
Voltage Output Term.
+ VDC power supply for Speed Pot (1 maximum).
(Speed Pot Power)
Cl Frequency Setting
Current Input When 4 to 20mA DC is input, the maximum frequency is reached at
20mA. The output frequency is proportional down to 4mA.
Vi Voltage Input
Auxiliary Terminal Reaches maximum output frequency at 0 VDC (the output
freq. is proportional down to 0 VDC). Input impedance is 22K ohms.
FM1
FM2 Frequency Meter
Connection Points Provides an output of 0 to VDC VDC at max. frequency).
Available for connection of a voltmeter (with internal resistance of
1 OK ohms). FM1 = Pos., FM2 = Neg. To output a digital signal,
SW2 must be changed to 2-3 position. (See Figure 4-9 and
Function Codes 40 and 50.)
