Maintenance Operations
Option Board Protection Function List
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).
•Protection function list when the PG board (3G3AX-PG01) is mounted
Note: Check the DIP switch settings on the PG board for any abnormal operation.
Function List of the DIP Switches on the PG Board (3G3AX-PG01)
•Protection function display when the digital command board (3G3AX-DI01) is mounted
Note: Input mode is determined by the combination of DIP and rotary switches. Check the settings of the DIP and
rotary switches on the digital command board for any abnormal operation.
Name Description Error Code
Encoder
disconnection
Shuts off the output and displays an error when the encoder wiring
disconnection or connection failure is detected, the encoder is
damaged, or an encoder except for line driver output is used.
E60.0 E70.0
Excess speed
Shuts off the output and displays an error when the motor rotation
exceeds the maximum frequency (A004) × the overspeed error
detection level (P026).
E61.0 E71.0
Positioning error
Shuts off the output and displays an error when the current position
deviation against the position reference value exceeds 1,000,000
pulses during position control.
E62.0 E72.0
Position control
range trip
Shuts off the output and displays an error when the current position
exceeds the setting values of the position limit range specification for
Forward (P072) and Reverse (P073) during absolute position control.
E63.0 E73.0
3G3AX-PG01
connection error
Shuts off the output and displays an error if a connection (mounting)
failure of the PG board is detected.
E69.0 E79.0
DIP switch Switch No. Description
SWENC
1
ON
Disconnection detection enabled when the encoder A/B-phase is not
connected
OFF
Disconnection detection disabled when the encoder A/B-phase is not
connected
2
ON
Disconnection detection enabled when the encoder Z-phase is not
connected
OFF
Disconnection detection disabled when the encoder Z-phase is not
connected
SWR
1
ON With the termination resistor between SAP and SAN (150 )
OFF Without the termination resistor between SAP and SAN
2
ON With the termination resistor between SBP and SBN (150 )
OFF Without the termination resistor between SBP and SBN
Name Description Error Code
3G3AX-DI01
error
Shuts off the output and displays an error if a timeout occurs in
communication between the Inverter and digital command board.
