LED display Description Cause Possible solutions
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 pa-
rameter 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 communication
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.
CE
FB
PID feedback
loss
PID feedback signal falls below
level specified in 10-12 (PID feed-
back 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
Run Permissive
Run permissive input open (F1,
F2).
•Terminal board Input F1 and F2 are not
connected
•Check F1 and F2 connection
SS1
Digital input Stop
command
