⚫ Check the safety conditions surrounding the motor and load machineries before
autotuning as physical injury may occur due to sudden start of motor during autotuning.
⚫ Although the motor does not run during static autotuning, the motor is stilled supplied
with power, do not touch the motor during autotuning; otherwise electric shock may
occur.
If the motor has been connected to load, do not carry out rotary autotuning; otherwise
malfunction or damage may occur to the VFD. If rotary autotuning is carried out on a motor
which has been connected to load, wrong motor parameters and motor misacts may occur.
Disconnect the load to carry out autotuning if necessary.
The ST600 Series VFD can drive asynchronous motors and synchronous motors, and it supports two
sets of motor parameters, which can be switched over by multi-function digital input terminals or
communication modes.

The control performance of the VFD is based on accurate motor model, therefore, users need to carry
out motor parameter autotuning before running the motor for the first time (take motor 1 as an example)
