5-2 Cause and Countermeasure of
Option Errors
The Inverter stops and displays an error in the following cases.
*1
Appears when the PG Board is connected to Board port 2.
*2
Upper limit value is applied when the frequency upper limit (A061) is set.
*3
This error could occur again even if the trip is reset during free running. Reset the trip after
stopping motor operation.

Description
Remedy
Encoder
disconnection
Detects encoder disconnection and
connection failure.
Check the connection and con-
ductive wire of encoder line.
Detects if the encoder has broken or
the encoder is not the one that spec-
ifies the line driver output.
Use the specified encoder instead.
Detects if an encoder without phase
Z has been used
Turn OFF the SWENC-2 on the
PG Board.
Overspeed
Detects if the motor rotation has ex-
ceeded (Maximum frequen-
cy
*2
)
×
(Overspeed error detection
level [P026]).
*3
Adjust the parameters of Kp and J
relating to the speed control and
reduce overshooting.
Positioning
error
Detects if the current position devia-
tion against the position command
value exceeds 1,000,000 pulses
during position control.
Set the larger value for position
loop gain of position control.
Reduce the pulse per unit time of
the pulse train position command
input.
Position con-
trol range trip
Shuts off the output and displays an
error when the current position ex-
ceeds the set values for the position-
ing range specifications for both
Forward (P072) and Reverse (P073)
during absolute position control.
Correct the position command.
3G3AX-PG
connection

Detects PG Board connection
failure.
Check the PG Board connection.
