From the DC voltage at terminals C/L+ and D/L-, inverters generate a
three-phase system of variable output frequency with the method of
pulse width modulation (PWM) for feeding three-phase motors at
terminals U2/T1, V2/T2, W2/T3.
When the DC link is charged the control board is supplied with voltage
by an integral power supply unit. If the DC link is discharged, the control
board can be fed via an external 24 V supply at terminal X9.
The unit functions are controlled by the software on the control board.
The unit can be operated via the PMU operator control panel, the user-
friendly OP1S operator control panel, the terminal strip or via a bus
system. Option boards can be used to expand the unit's functions.
Pulse encoders and analog tachometers can be used as motor
encoders.
The power section and the electronics of the inverter are cooled by a
fan. The customer must connect up 230 V AC (50/60 Hz) to the
terminals X18/1...5 to supply the fan.
