Display Error
Description
Zero speed stop
It happens as set frequency <0.1Hz
Fail to start
directly
1. If the inverter is set to external control mode (F04=001), and
direct start is disabled (C09=001), the inverter cannot be
started and will flash STP1 when Run switch is in ON
position when applying power (see descriptions of C09).
2. Direct start is possible when C09=000.
Keypad
emergency stop
1. If the inverter is set as external control mode (F04=001)
,
the inverter will stop according to the setting of F9 when
stop key is pressed. STP2 flashes after stop. Turn the Run
switch to OFF and then ON again to restart the inverter.
2. If the inverter is in communication mode and Stop key is
enabled, the inverter will stop in the way set by F9 when
Stop key is pressed during operation and then flashes STP2.
The PC has to send a Stop command then a Run command
to the inverter for it to be restarted.
External
emergency stop
The inverter will decelerate to stop and then flashes E.S. when
there is an external emergency stop signal via the
multi-function input terminals(see descriptions of F11~F14).
External base
block
The inverter stops immediately and then flashes b.b. when
external base block is input through the multi-functional input
terminal (see descriptions of F11~F14).
PID feedback
broken
PID feedback signal circuit error detection
REMOTE
KEYPAD cable
broken
1. REMOTE KEYPAD does not connect with REMOTE
KEYPAD, such signal will be displayed.
2. REMOTE KEYPAD connects with main KEYPAD, such
signal will be displayed.
3. REMOTE KEYPAD and main KEYPAD both display such
signal means communication errors.
