Err15
Output
abnormal
● Braking (resistor) short
occurs on the output side.
● The RUN contactor is
abnormal.
● Check wiring of the regen. resistor and
braking unit is correct, without short
circuit.
● Check whether the main contactor works
properly and whether there is arch or
stuck problem.
● Contact us or directly our agent.

Err16
Current control
fault
● Subcodes 1, 2: The
current deviation is too
large.
● Subcode 3: The speed
deviation is too large.
Subcodes 1, 2:
● Check whether the input voltage is low
(often in temporary power supply).
● Check whether cable connection
between the controller and the motor is
secure.
● Check whether the RUN contactor works
properly.
Subcode 3:
● Check the circuit of the encoder:
Check whether encoder pulses per revolution
(PPR) is set correctly.
Check whether the encoder signal is
interfered with, whether the encoder cable
runs through the duct independently, whether
the cable is too long, and whether the shield
is grounded at one end.
Check whether the encoder is installed
reliably, whether the rotating shaft is
connected to the motor shaft reliably by
observing whether the encoder is stable
during normal-speed running.
● Check whether the motor parameters are
correct, and perform motor auto-tuning
again.
● Increase the torque upper limit in F2-08.
