The external braking resistor must be parameterized via the firm‐
ware to protect the drive controller and the braking resistor
against overload.
See also Parameter Description of the firmware used:
"P-0-0860, Converter configuration"
and
"P-0-0858, Data of external braking resistor"
The drive controller monitors the operating data of the external
braking resistor against the data in "P‑0‑0858, Data of external
braking resistor". Select braking resistors with a performance that
corresponds to the parameterized values or more powerful brak‐
ing resistors.
X9, External Braking Resistor HCS02.1E-W0054 and -W0070
Function, Pin Assignment
X9 is used to connect an external braking resistor which is controlled via the
internal switch.
For HCS02 devices, the connection X9 is contained in all designs,
except for ‑W0012 and ‑W0028.
