This input can be used to drain the drive system’s DC bus down.
Closing a contact across this input will force the IGBT to go full on
and stay until the input is removed.
Use this input with care
. If the DC Bus still has incoming power
enabled, the braking resistor will go full on, and will stay on as long
as this input is closed. This can cause resistor overheating as well
as stress to the DC Bus rectifier section.
DO NOT use this input as a clamp for maintenance purposes.
Always ensure that voltage levels are safe and the equipment power
source is properly locked out before attempting maintenance of any
kind.
The Bus Discharge function is useful to quickly drain the DC Bus to allow
for safe working voltages in the drive systems with large capacitor banks.

Interface Standard:
3-wire RS-485 multi-drop, half-duplex (D, D-
bar, and Common), asynchronous.
Command/Response Protocol:
Standard PROFIBUS DP (Master/
Slave) protocol per European Norm EN50170.
Baud Rate:
Supported baud rates are 9600, 19.2K, 45.45K, 93.75K,
187.5K, 500K, 1.5M, 3M, 6M, and 12M bits per second, auto-
detected. Maximum transmission length is dependent on baud rate
selection (range is up to 1200M at 9600bps, or up to 100M at
12Mbps). Refer to the following table for maximum transmission
distances at supported baud rates using recommended type A
(<30pF/M), or alternately type B (<60pF/M) bus wire (see EN50170):

Parity:
Even parity.
Stop Bits:
One.
Address:
Set via two rotary hexadecimal switches adjacent to the
power terminals, or alternately via the Set Slave Address command.
Valid setting is 0-125 (7 bits).
Address 126 (7Eh) is a default factory address reserved for
commissioning purposes only. Address 127 (7Fh) is reserved by the
software as a global address for broadcast messages.
If the address switches are set to 126 upon power-up (or 126 to 254),
then the unit will retrieve its address from its internal EEPROM rather
