Display Error
Description
Zero speed stop Set frequency is <0.1Hz Increase set frequency
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 the Run switch is ON when
applying power (see descriptions of C09).
2.
Direct start is possible when C09=000.
Keypad
emergency stop
1.
If the inverter is set to external control mode (F04=001), the
inverter will stop according to the setting of F9 when the
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 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
signal loss
PID feedback signal circuit error detection
REMOTE
KEYPAD cable
broken
1. When REMOTE KEYPAD does not connect with inverter,
this signal will be displayed on the Remote keypad.
2. When REMOTE KEYPAD connects with inverter, this
signal will be displayed on the main keypad.
3. When both REMOTE KEYPAD and main KEYPAD display
this signal means communication errors.
