Item no. Description
1 Supply L1, L2 L3, PE, input supply voltage U
LN
= Ue at 50/60 Hz:
D_1-32: 230 V class, three-phase input connection (3 AC 230 V/240 V)
D_1-34: 400 V class, three-phase input connection (3 AC 400 V/480 V)
D_1-35: 600 V class, three-phase input connection (3 AC 600 V)
2 Internal interference suppression filter, category C2 to IEC/EN 61800-3
EMC-connection of internal interference suppression filter to PE
3 Rectifier bridge, converts the AC voltage of the electrical network into DC voltage
4 DC link with charging resistor, capacitor and switching mode power supply unit
(SMPS = Switching Mode Power Supply):
DC link voltage UDC with three-phase input connection (3 AC): U
DC
= 1.41 x U
LN
5 Inverter. The IGBT based inverter converts the DC voltage of the DC link (UDC) into a three-phase AC voltage (U2) with variable amplitude
andfrequency (f2). Sinusoidal pulse width modulation (PWM) with V/f control can be switched to speed control with slip compensation
6 Motor connection U/T1, V/T2, W/T3 with output voltage U2 (0–100% Ue) and output frequency f2 (0–400 Hz) output current (I2):
D_1-32: 3.7 A to 248 A
D_1-34: 2.2 A to 245 A
D_1-35: 3.3 A to 208 A
100% at an ambient temperature of 122°F (50 °C) with an overload capacity of 150% for 60 s every 600 s and a starting current
of 200% for 2 s every 20 s
7 Keypad with control buttons, graphic display, control voltage, control signal terminals, micro-switches, and interface for the
PC interface module (option)
8 Three-phase asynchronous motor, variable speed control of three-phase asynchronous motor for assigned motor shaft power values (P2):
D_1-32: 0.55 kW to 75 kW (230 V, 50 Hz) or 0.75 hp to 100 hp (240 V, 60 Hz)
D_1-34: 0.75 kW to 132 kW (400 V, 50 Hz) or 1 hp to 200 hp (460 V, 60 Hz)
D_1-35: 1.5 kW to 132 kW (600 V, 50 Hz) or 2 hp to 200 hp (600 V, 60 Hz)
9 DC link—chokes, to minimize current harmonics
