ER0-04
Tolerance alarm
1)
Mechanical choked to death
2)
Input pulse frequency is too high
3)
Encoder zero change in
4)
Encoder wiring error
5)
P16 position loop gain is too small
6)
Less torque
7)
P15 parameter setting is too small
8)
P15 = 0 shields this feature, resulted in no alarm

ER0-07
CW Motor Forward
limit
Hit the forward limit switch, you can set the parameter
P7 = 0 to shield this feature or reversely rotate motors.
ER0-08
CCW
Motor
Reverse limit
Hit the reverse limit switch, you can set the parameter
P7 = 0 to shield this feature or reversely rotate motor.
ER0-09
&
ER0-19
Encoder fault
1)
Encoder damage
2)
Encoder wiring is damaged or broken
3)
P33 = 1 shields this feature, resulted in no alarm
4)
Encoder cable is too long, resulting in low encoder
supply voltage
ER0-10
Motor
overload
alarm
Overload excesses the parameters of motor rated
torque:
More than 150% rated overload: over 10000 ms;
More than 300% rated overload: over 1000ms;
More than 500% rated overload: over 10ms
The machine is stuck for rigidity is adjusted too strong;
Speed increase and decrease are too fast.
