IS200EPSMG2ADC Electrical module

There is an enable input and a relay output on the chopper control board. The input can be connected to a temperature sensitive switch mounted in the resistor assembly to protect the resistor against overtemperature (see Chapter 4 – Electrical Installation for more information). The relay output indicates chopper faults. The chopper can be controlled from an external control location via a fibre optic link. Using the link it is possible to synchronise several braking choppers. In standard applications the fibre optic link is not used. Accessories It is highly recommended to equip the ACS 600 with a main contactor controlled by the chopper relay output. This configuration also requires a manual start/stop switch for system start-up. For more information, see Chapter 4 – Electrical Installation. Delivery Check The package contains: • Braking chopper type NBRA-6xx (check the correct type with Table 2-1) • Installation and Start-up Guide for NBRA-6xx (this document). Warranty See the Installation and Start-up Manual delivered with the frequency converter for warranty information.

Braking Resistors

Standard resistors are available for each ACS 600 / NBRA-6xx combination. These resistors are specified in Table 2-1, and their dimensions given in Appendix A. (Some combinations require the use of two parallel-connected resistors.) Other resistors with a resistance not below the minimum allowed resistance value (R) may also be used. WARNING! Never use a braking resistor with a resistance value below the minimum allowed resistance value specified for that particular ACS 600 / braking chopper combination. The chopper and the frequency converter are not able to handle the overcurrent caused by the low resistance. If the heat dissipation capacity (ER) of the standard braking resistor is not sufficient for the application, it is possible to use a four resistor assembly in which two standard resistors are connected in parallel and two in series. This implementation does not change the total resistance of the resistor assembly
