E6*. (OP1-*) appears when the option board is mounted on option port 1 (Digital Operator connecter
side), and E7*. (OP2-*) appears when it is mounted on option port 2 (control circuit terminal block
side).
 Function List for the DIP Switches on PG Board (Model: 3G3AX-PG01)
Use the DIP switches on the PG Board to enable/disable the encoder disconnection detection
function and terminating resistor.

Name Description
Alarm code on
Digital Operator
Encoder disconnection
The inverter shuts off its output and displays an alarm if the
encoder wiring disconnection or connection failure is detected,
when the encoder is damaged, or when an encoder except for
line driver output is used.
E60., E70.
Overspeed
The inverter shuts off its output and displays an alarm if the
motor rotation speed reaches or exceeds the 1st Maximum
Frequency (A004) × the Overspeed Error Detection Level (P026).
E61., E71.
Positioning error
The inverter shuts off its the output and displays an alarm if the
current position deviation from the position reference value
reaches or exceeds 1,000,000 pulses during position control.
E62., E72.
Position control range
trip
The inverter shuts off its output and displays an alarm if the
current position exceeds the value set in the Position Limit
Setting (Forward Side) (P072) Position Limit Setting (Reverse
Side) (P073) during absolute position control.
E63., E73.
3G3AX-PG01
connection error
The inverter shuts off its output and displays an alarm if a PG
board connection (mounting) failure is detected.
E69., E79.
