Description
Cause
Possible solutions
PGO
PG
Open circuit
PG pulses are not received
by the inverter for the time
specified in 20-26 (PG
open circuit detection time).
This fault is active V/F +
PG and SV control mode
(00-00 = 1 or 3 or 4).
PG cable disconnected.
PG has no power.
Mechanical brake active preventing
motor from turning.
Check PG wiring.
Check PG power-supply.
Make sure brake is
released.
DEV
Speed
deviation
Motor speed rises above
20-23 level (PG speed
deviation level) for the time
specified in 20-24 (PG
deviation time)...Active
when parameter 20-22(=0
or 1). This fault is active
V/F + PG and SV control
mode (00-00 = 1 or 3 or 4).
Load too heavy
Mechanical brake active preventing
motor from turning.
PG wiring error.
PG parameters (group 20) set
incorrectly.
Acceleration / deceleration time set
to short.
Check load
Make sure brake is
released.
Check PG wiring.
Check PG parameters
20-23/20-24.
Increase Acceleration /
deceleration time.
CE
communicati
on error
No Modbus communication
received in for the time
specified in 09-06
(communication error
detection time).
Active when 09-07(= 0 to
2).
Connection lost or wire broken.
Host stopped communicating.
Check connection
Check host computer /
software.
FB
PID feedback
loss
PID feedback signal falls
below level specified in
10-12 (PID feedback loss
detection level) for the time
specified in 10-13
(Feedback loss detection
time). Active when
parameter (10-11 = 2).
Feedback signal wire broken
Feedback sensor broken.
Check feedback wiring
Replace feedback
sensor.
STO
Safety
switch
Inverter safety switches
open.
Terminal board Input F1 and F2 are
not connected
Check F1 and F2
connection
SS1
Safety
switch
Inverter safety switches
open.
08-30 =0 and 03-00~03-07=58
Check if 08-30 =0 and
03-00~03-07=58
