Page 9: External Brake Resistor
3.3 External brake resistor With KU inverters without regenerative braking, excess brake energy has to be converted to heat with an external brake resistor. The brake transistor is integrated in the KU inverter. The external brake resistor has to be connected via terminal X04 (RBP/RBN) with shielded cable. The shield must be grounded to PE at both ends. -

Page 13: Functional Description
5.2 Functional description The central module AZ contains the following functional groups: Rectifier for generating the DC-Bus voltage respectively controlled rectifier bridge for inverters with regenerative braking. Charging device for the DC-Bus Brake transistor Braking energy from the motor is first fed into the DC-Bus. If the DC-Bus voltage exceeds its limit value, the brake transistor is activated and the surplus braking energy is converted into heat through the brake resistor. -

5.3 KU 25-1 / KU 40-1 / KU 50-1 KU inverters with regenerative braking The regenerative braking is activated by the KU system software. Through bit 17 of ID32773 the initialization of this function can be selected depending on: Regenerative braking is initiated after „Inverter On“ handshake QRF (default setting) ID32773, Bit 17 = 0: Regenerative braking is initiated already after „DC BUS Enable“... - Page 15 Error condition for regenerative braking because of regenerative overcurrent. The LED state is maintained until „Error reset“ (FL) was activated or power was turned off. Possible causes: Regenerative overcurrent. Supply voltage dip. Missing of a line half-wave or phase failure. Line undervoltage.

Page 24: Information For Motor Exchange
Pay attention to the correct phase-sequence! Incorrect phase-sequence reverses motor direction! By this false control direction! Switching on with false phase sequence results in an uncontrolled rotation of the motor shaft with possible damages in the installation! Warning 16. If used: Securely connect brake resistor (X04). 17. - Page 25 AMK Arnold Müller GmbH & Co.
