Alarm code numbers flash at the panel when the controller generates an alarm.
If you need more detailed information about errors and error history, please connect the
controller to the PC via RS232 and refer to chapter 5.7.
Table 8-1: Alarm codes of Error_State1
The current motor type is different from
the motor type which is saved in the
controller.
Method 1: Access EA01 via the KEY, and
confirm motor type, then access EA00, set
2. Method2: Access EASY_MT_TYPE
(0x304101) via PC software, confirm the
value, then save the parameter.
Errors occurs
in Error_State2
Press the SET key to enter Error_State2
(d1.16), read the error bit, check the error
meaning in table 8-2.
The encoder wiring is incorrect or
disconnected.
Use a multimeter to check connection of
the encoder signal cable
Internal encoder erroror the encoder is
damaged.
1. Access panel address d3.51 Encoder_OP
by KEY and set 1.
2. Try to reset the controller error. If
error persists, replace the motor.
Make sure the equipment is well grounded
The temperature of controller’s power
module has reached the alarm value.
Improve the cooling environment of
the controller.
Supply power voltage exceeds the
allowable input voltage range
In case of emergency stop, there is no
external braking resistor or braking.
Check to see if supply power voltage is
unstable and if a suitable braking resistor
is connected.
The power voltage input is lower than
the low voltage protection alarm value.
Check to see if supply power voltage is
unstable.
Instantaneous current exceeds
the overcurrent protection
value.
Check the motor cable for short circuits.
Replace the controller.
The braking resistor is overloaded or it’s
parameters are not set correctly.
Set the resistance and power of the
external braking resistor through d5.04
and d5.05.
