(3)Resetting System after Error Codes
There are 2 methods of releasing error codes.
・Push Error Reset Switch ⑰
RESET on the front panel.
・Switch the signal on PIN4(RESET) of Input/Output Connector A OFF(Open)-ON(Closed)-
OFF(Open).
(4)Torque Overload
When the Load Monitor LED (Load) ⑱ lights 4 or more LEDs (3 green LEDs and 1or more yellow
LEDs) an overload condition exists. During overload operation the follow occurs.
・WARNING LED (Warning) ⑳
flashes
・WARNING Code A3 is displayed on the Digital Speed Indicator ⑪
・WARNING Signal is output to the WARNING Signal PIN20 (Warning) of Input/Output Connector A
Overload operation is considered short term operation mode. The allowable operation time depends
on the number of lighted LEDs on the Load Monitor LED (Load) ⑱. The allowable time is detailed
below.
・Load Monitor LED 4 LEDs: 40 Seconds
・Load Monitor LED 5 LEDs: 20 Seconds
・Load Monitor LED 6 LEDs: 10 Seconds
When the allowable time is exceeded the motor will stop and the following occurs.
・Error LED (Error) ⑲ flashes
・Error Code E8 is displayed in the Digital Speed Indicator ⑪.
・Error Signal is output to the error signal PIN8(ERR) of Input/Output Connector A.

Trouble
Motor Current beyond safe limits.
Motor Voltage beyond safe limits.
Trouble with the sensor signal in the motor.
Internal Temperature of the Control Unit too High.
Trouble with the motor brake circuit.
Motor stalled for more than 3 seconds.
Inadequate air supplied for more than 4 seconds during rotation
or inadequate air supply when motor start commanded.
Torque limits exceeded for too long a period of time.See (4) on Page 24.
Trouble with the power source inside the control unit.
External control sequencing problem.
Trouble with memory (EEPROM) .
Rotating speed is beyond the set speed for too long.
Note: ・When using the Input/Output Connector and external monitoring, please check and resolve
the source of the trouble anytime a WARNING Code is displayed.
・The following Error Codes cannot be released: E4(Control Unit Overheat), E5(Brake Circuit
Trouble), E9(Trouble with Power Source), EC(Internal Memory Error). Once the source of
the error is corrected, turn the system off and the Error Code will be released when the
system is turned on.
