The rated line voltage (p0210) must be parameterized during commissioning.
For the 20 kW and 40 kW Basic Line Modules booksize, the temperature switch of the
external braking resistor must be connected to X21 on the Basic Line Module.
If a braking resistor has not been connected for 20 kW and 40 kW Basic Line Modules
booksize, the Braking Module must be deactivated via p3680 = 1.
An optional Braking Module can be externally mounted on the Basic Line Module chassis. A
braking resistor must then be connected to the Braking Module.
If several Motor Modules are supplied from a non-regenerative infeed unit (e.g. a Basic Line
Module), or for power failure or overload (for SLM/ALM), the V
dc_max
control may only be
activated for a Motor Module whose drive should have a high moment of inertia.
For the other Motor Modules this function must be disabled or monitoring must be set.
If the V
dc_max
control is active for several Motor Modules, then for an unfavorable
parameterization, the controllers can mutually influence one another negatively. The drives
can become unstable, individual drives can unintentionally accelerate.
