4.2 Power element
4 Function description
4.2 Power element 4200 Power element 4- ][Funktion_Leistungsteil
The power element of the servo amplifier converts the fixed voltage and
frequency of the mains into a variable voltage and frequency for driving
the motor This means that the rotational speed and torque are infinitely
variable. The power element consists of:
 Filter A
 Rectifier B
 Charging circuit with intermediate circuit C
 Brake chopper D
 Inverted rectifier E

4.2.1 Mains voltage
Mains voltage 4- ][Funktion_Netzspannung_DD5
The servo amplifier is suitable for connection to TT and TN networks.
Depending on the device type, the voltage range of the servo amplifier is
 3 x 110 VAC – 3 x 230 VAC or
 3 x 208 VAC - 3 x 480 VAC.
Please note the maximum permitted voltages between the external con-
ductors (L1, L2, L3) and the servo amplifier housing:
 Periodic overvoltages between the external conductors and the hous-
ing: Max. 1000 V (amplitude)
 Voltage spikes (< 50 μ s) between the external conductors in accord-
ance with EN 61800: Max. 1000 V
 Voltage spikes (< 50 μ s) between the external conductors and the
housing: Max. 2000 V
Direct connection to PMCtendo DD5
 110 – 230 V mains supplies without earthed star point (asymmetrically
earthed or unearthed mains supplies), see Fig. (1) – (5)
 400 – 480 V mains supplies with earthed star point, see Figure (6)
