Brake resistor connection data
The brake resistor output is conditionally short-circuit proof by
IEC/EN 61800-5-1 and UL 61800-5-1.
Short-circuit protec-
tion
(IEC 61800-5-1,
IEC 60439-1,
UL 61800-5-1)
Rated conditional short-circuit current is as defined in IEC 60439-1.
Control connection data
The data is valid for the standard drive variant (base unit equipped with the I/O & EIA-485
module (RIIO-01)).
