Maintenance Operations
Encoder
disconnection
The Inverter is tripped if the motor
rotations detected by the motor are less
than the Starting Frequency (b082) for
longer than the Encoder Disconnection
Detection Time (P077, P077 ≠ 0) when
the output frequency is equal to or
higher than the Creep Speed Setting
(P015).
E80.
 The encoder wiring is
disconnected or there is a
faulty connection.
→Check the encoder
wiring.
The actual motor rotations is
less than the Starting
Frequency (b082) for longer
than the Encoder
Disconnection Detection
Time (P077).
→Adjust the parameters.
Increase the setting in P077
and P015.
This error also occurs if the
number of motor rotations is
less than the starting
frequency during simple
position control.
→Adjust the parameters.
Increase the setting in P077
and P015.

Excess speed The Inverter is tripped when the motor
rotations equal or exceed the maximum
frequency times the Overspeed Error
Detection Level (P026 ≠ 0).
E81.
 This is determined via speed
detection with the encoder.
The encoder wiring is
disconnected or there is a
faulty connection.
→Check the encoder
wiring.
The number of encoder
pulses is not correct.
→Check the Number of
Encoder Pulses (P011).
The actual motor rotations
exceeded the error detection
level.
→Adjust the Overspeed
Error Detection Level (P026)

Position control
range trip
A trip will occur if the current position
exceeds the Position Range Setting
(P072, P073) during simple position
control.
E83.
 Check the current position.
→Check parameters P072
and P073.
→Check the zero point.
