Frequency reference loss is detected when the frequency reference drops below
10% of the reference within 400 ms.
177
D Braking resistor fault DB Overheat Closed: Braking resistor or transistor is overheated or faulted out. 177
E Fault Fault Closed: Fault occurred. 177
F Through mode Not Used Set this value when using the terminal in the pass-through mode. 177
10 Minor fault Minor Fault
Closed: An alarm has been triggered, or the IGBTs have reached 90% of their
expected life span.

1E Restart enabled Dur Flt Restart Closed: Automatic restart is performed 180
1F
Motor overload alarm
(oL1)
Overload (OL1)
Closed: oL1 is at 90% of its trip point or greater. An oH3 situation also triggers
this alarm.
180

During frequency
output
During RUN 2
Open: Either the drive has stopped or baseblock, DC Injection Braking, or Initial
Excitation is being performed.
Closed: Drive is running the motor (not in a baseblock state and DC Injection is
not being performed).

38 Drive enabled Drive Enable
Closed: Multi-function input set for “Drive enable” is closed (H1-oo = 6A)
180
39 Watt hour pulse output Watt-hour Pulse
Output units are determined by H2-06. Outputs a pulse every 200 ms to indicate
the kWh count.
