Brake detection input
For starting Brake detection macro of tower crane, conducting Brake detection
automatically. The inspection process takes 30 seconds.
Xi=27~50
Not apply to hoisting
Xi=51
External device fault input
After the terminal receives external device fault signal in operation, inverter stops and
enters fault status. The default is NO input of external fault, and it can be set as NC input by
terminal positive/negative logic of FE-01.
No.

EM330D provides 3 programmable output terminals including 2 multi-function output
terminals and 1 relay output terminal. There are 0
～
32 program codes, user can define
output variables of terminals.
2 multi-function output terminals are in OC output mode, output common port is connected
to COM. When selected program code is enabled, the electronic switch is ON, and when it
is disabled, the electronic switch is OFF. OC can be powered either internally or externally,
as shown in Figure 7-6(a) and 7-6(b) respectively. If it is externally powered, the voltage
range is required to be within 8~24V.
