Stop/Reset
Stop/Reset
When the command given channel is keyboard control, press
this key to stop the inverter; the parameter [F04.08] can be used
to define whether other command channels are valid; the
inverter resets when pressing the key in fault status.
G
Digital potentiometer: clockwise to increase the operating value,
counterclockwise to decrease the operating value
Set key: After modifying the value, press this key to confirm the
modified value.
Left/Right Shift
Move left and right operation bits
H
Jog/Reverse
Select the function of the key by parameter [F04.07], 0: reverse
1: jog

Chapter 5 Fault Diagnoses and Processing
This chapter explains the display content and processing of the inverter fault, alarm and operation fault. It also simply
explains the bad situation caused by inverter or motor fault and how to solve it. For the adjustment guide in trial run,
please refer this chapter too.
5.1
Fault Types
Type
Inverter action while fault happens
External fault
In certain application occasions, external related equipments fault signals are considered in
the inverter control system as usage of monitoring, protection or switch control. At this time,
if one multi function terminal is defied as “external fault”, the inverter stops output alarm
signal.
