Function:
The output is high when the frequency
converter is in Hand on mode (as
indicated by the LED light above [Hand
on].
The output is high when the frequency
converter is in Hand on mode (as
indicated by the LED light above [Auto
on].
The frequency converter/system has
turned into sleep mode. See par. 22-4*.
A Broken Belt condition has been
detected. This function must be enabled
in 22-60 Broken Belt Function.
The frequency converter is operating in
Fire Mode. See parameter group24-0* Fire
Mode.
To be used as signal for activating an
external electromechanical bypass
switching the motor direct on line.
See 24-1* Drive Bypass.
Function:
digital outputs and relays that is
controlled by bus.
A logical '1' indicates that the output is
high or active.
A logical '0' indicates that the output is
low or inactive.
