Encoder
disconnection The inverter trips, when the output fre-
quency is at the Creep Speed Setting
(P015) or higher, if the motor rotation
speed detected by the encoder
remains lower than the Starting Fre-
quency (b082) for the duration set in
the Encoder Disconnection Detection
Time (P077
≠ 0) or longer.
E80.
The encoder wiring is discon-
nected or connected improperly.
• Check the encoder wiring.
The actual motor rotation speed
remains lower than the Starting
Frequency (b082) for the duration
set in the Encoder Disconnection
Detection Time (P077) or longer.
• Adjust the parameter values.
Set a slightly longer time in
P077 and a slightly higher
value in P015.
This alarm also occurs if the
motor rotation speed drops to
lower than the Starting Frequency
under simple position control.
• Adjust the parameter values.
Set a slightly longer time in
P077 and a slightly higher
value in P015.

Overspeed The inverter trips if the motor rotation
speed exceeds the value set in Maxi-
mum Frequency
×
Overspeed Error
Detection Level (P026 ≠ 0).
E81.
This alarm is displayed based on
the speed detected by the
encoder.
The encoder wiring is discon-
nected or connected improperly.
• Check the encoder wiring.
The Number of Encoder Pulses
does not match.
• Check the number of
encoder pulses. (P011)
The actual motor speed is higher
than the error detection level.
• Adjust the Overspeed Error
Detection Level (P026) set-
ting.

Position
control range
trip The inverter trips if the current posi-
tion is out of the range set in the Posi-
tion Limit Setting (P072, P073) during
simple position control.
E83.
Check the current position.
• Check the parameter settings
(P072, P073).
• Check the origin.
