Basic Line Modules in booksize format

Basic Line Modules are used for applications in which no energy is returned to the supply or where the energy exchange between motor and generator axes takes place in the DC link. Basic Line Modules can only feed energy from the supply system into the DC link, energy cannot be fed back into the supply system. The DC link voltage is directly derived from the 3‑phase line voltage via a 6‑pulse bridge circuit. Basic Line Modules are designed for connection to grounded, star TN/TT systems and non-grounded, symmetrical IT systems. The connected Motor Modules are pre-charged over the integrated pre-charging resistors (20 kW and 40 kW) or through activation of the thyristors (100 kW).

The 20 kW and 40 kW Basic Line Modules are equipped with an integrated brake chopper. With the addition of an external braking resistor, they can be used for applications with intermittent regenerative operation such as stopping. A Braking Module is required with a 100 kW Basic Line Module in addition to an external braking resistor for regenerative operation.

Braking power with external brake resistance

The following load cycles are defined for the braking modules of the 20 kW and 40 kW Basic Line Modules:

The maximum possible braking power P_max is calculated using the following formula:

P_max = U²/R

U = Activation threshold

R = Resistance value of the external braking resistor

The maximum braking power is achieved with the smallest permissible resistance value. The maximum possible braking power falls at larger resistance values.

Braking power of the 20 kW Basic Line Modules depending on the connected braking resistor

When the recommended braking resistor is used, the following values result for the maximum braking power or continuous braking power:

Braking resistor 6SE7023‑2ES87‑2DC0
Resistance value = 20 Ω → max. braking power = 30 kW;
continuous braking power = 5 kW

Braking power of the 40 kW Basic Line Modules depending on the connected braking resistor

When the recommended braking resistor is used, the following values result for the maximum braking power or continuous braking power:

Braking resistor 6SE7028‑0ES87‑2DC0
Resistance value = 8 Ω → max. braking power = 75 kW;
continuous braking power = 10 kW (limited by braking module)

Интеграция

The Basic Line Module communicates with a CU320‑2 or SIMOTION D4x5 2 Control Unit or Controller Extension CX32‑2 via DRIVE‑CLiQ.

Connection example for 20 kW and 40 kW Basic Line Modules in booksize format

Note: The thermostatic switch built into the braking resistor must be looped into the shutdown chain of the drive to prevent thermal overloading of the system in the event of a fault. If a braking resistor is not connected, a jumper must be connected between X21.1 and X21.2.

Технические данные

¹⁾ The DC link voltage is unregulated and load-dependent. For further information see chapter System description – Dimensioning.

¹⁾ Power loss of Basic Line Module at rated output including losses of 24 V DC electronics power supply.

²⁾ Nominal HP ratings are provided for ease of assigning components only. The Line Module outputs are dependent on the Motor Module loading and are to be dimensioned accordingly.
